Dell PowerEdge R740xd2 — Full Specs Breakdown & Buyer's Guide
The 2U Dense-Storage Platform for Bulk Repositories, NL-SAS Arrays, Backup, and Data Ingest
Bulk Capacity Backup Repositories — Up to 24 × 3.5-inch NL-SAS or SATA drives delivering 384 TB raw in a single 2U chassis provides the lowest cost-per-terabyte footprint for Veeam, Commvault, or Veritas NetBackup on-premise backup targets without requiring external JBODs or NAS appliances that add cabling, power, and licensing overhead
Surveillance Video Retention — Long-duration multi-camera video archives at 720p, 1080p, or 4K require sustained write throughput into cost-effective spindle drives; the R740xd2's 24-bay SATA/NL-SAS front chassis provides the drive count and sequential write bandwidth per slot needed by video management software to record and retain more cameras per server
Hydrological, Seismic, and Scientific Data Ingest — Research and government environments ingesting continuous sensor streams from GPS, LIDAR, weather, or seismic arrays require sustained write throughput into low-cost spinning media with moderate compute; the dual Xeon Scalable CPU pair and triple-channel PCIe connectivity handle ingest agent compute while 24 NL-SAS drives provide the bulk landing zone
Software-Defined Object Storage Nodes — The R740xd2 pairs efficiently with MinIO, Ceph RadosGW, and OpenStack Swift object storage tiers; at 24 raw drives per node, single-erasure-coded object clusters achieve maximum density with HBA330 pass-through JBOD mode exposing all 24 drives for uniform OSD (object storage daemon) assignment without RAID overhead
Nearline SAN and NAS File Server — Running Windows Server DFS-Namespace, QNAP NAS OS, or TrueNAS as a 2U NAS head node, the R740xd2 aggregates 24 drives into RAID 6 or RAIDZ2 volumes with H740P hardware RAID for redundant nearline SAN/NAS storage serving Active Directory file shares to desktop clients at cost-efficient raw capacity tiers
HDFS Warm and Cold Storage Tiers — Hadoop Distributed File System data node deployments tier data over time from NVMe hot nodes to SAS warm nodes and then to SATA/NL-SAS cold nodes; the R740xd2 serves as the cost-optimized cold tier in a tiered HDFS cluster, delivering block-level ingest from Spark or Flink jobs into its 24 3.5-inch drive bays
Imaging, Archival, and Digital Asset Management — Hospitals, media companies, and film archives storing DICOM images, RAW photography, or digital cinema DCPs require dense local storage with straightforward RAID protection; the R740xd2's dual 12-drive backplane with H740P RAID 6 provides the storage reliability and density for multi-petabyte on-premises digital archives
Dual 2nd Generation Intel® Xeon® Scalable — Up to 22 Cores and 140 W TDP
2nd Gen Xeon Scalable (Cascade Lake-SP) — Dual LGA 3647 sockets supporting Bronze, Silver, and Gold 2nd Gen Xeon Scalable processors (max 22 cores on R740xd2) alongside validated 1st Gen Xeon Scalable SKUs; the 22-core Gold 6152 at 2.1 GHz and 140 W TDP represents the maximum CPU density SKU certified for the R740xd2 platform
Intel C621 Chipset — Platform Controller Hub provides PCIe 3.0 connectivity (including the Slot 6 PCIe x4 from PCH), 12×SATA 6 Gbps ports on the PCH (used by the dual-backplane SAS expander), Intel AMT, VT-d, Intel TXT, xHCI SuperSpeed USB 3.0, Intel Quick Assist Technology (QAT) with optional license, and Rapid Storage Technology Enterprise
Up to 44 Cores Dual-Socket — Two Gold 6152 CPUs deliver 44 cores and 88 threads for I/O-intensive storage workloads: Ceph OSD process threads consuming CPU for erasure coding, object hashing, and data placement; software RAID scrub cycles; file server SMB/NFS protocol stack; and concurrent NFS client connections across 24 spindle drives
Intel UPI Inter-CPU Interconnect — Up to 3 Intel Ultra Path Interconnect (UPI) links at 10.4 GT/s (Gold tiers) or 9.6 GT/s (Silver/Bronze tiers) between CPU sockets; NUMA-aware workloads distributing storage I/O across the dual 12-drive backplanes can route SAS expander traffic through the appropriate CPU local PCIe domain for reduced cross-socket memory latency
48 PCIe Gen 3 Lanes Per CPU — 96 total PCIe 3.0 lanes feed both internal PERC slots (serving the dual SAS backplanes), the LOM riser, and the rear general-purpose PCIe expansion slots simultaneously; the SAS expander on each 12-drive backplane connects via PCIe from the internal PERC slot, not directly to the CPU PCIe lanes
Intel AVX-512 — Advanced Vector Extensions 512-bit SIMD operations accelerate software-defined storage workloads: Ceph RADOS erasure coding performance (EC 4+2 and EC 6+2), LZ4/Zstandard compression in ZFS/Btrfs, AES-256 in-line encryption on SAS drives, and SHA-2 checksumming for data integrity verification on all 24 drive paths simultaneously
Single-Socket Supported — Single CPU (Processor 1 socket only) configuration supported with processor blank in socket 2; only the right low-profile riser (Slot 6 from PCH + Slot 5 from CPU1) is active in single-CPU mode; Internal PERC slot remains active for storage controller connectivity to both 12-drive backplanes through the SAS expander chain
16-Slot DDR4 RDIMM — Up to 1 TB at 2933 MT/s
16 DDR4 RDIMM Slots — CPU1 supports up to 10 DIMM slots and CPU2 supports up to 6 DIMM slots in the R740xd2; all 16 slots are active with dual-processor configuration; RDIMM is the only supported DIMM type — no LRDIMM, DCPMM, or NVDIMM-N variants are supported, making R740xd2 selection straightforward for storage-oriented deployments
Up to 1024 GB (1 TB) Total — Maximum memory capacity of 1024 GB (1 TB) using 64 GB RDIMMs across all 16 slots; the 64 GB RDIMM is validated with 2nd Gen Xeon Scalable processors only; entry configurations begin at 8 GB minimum using a single 8 GB RDIMM in the CPU1 primary slot position
DDR4 2933 MT/s (2nd Gen Xeon Scalable) — Achieves 2933 MT/s memory speed with 2nd Gen Xeon Scalable and 1 RDIMM per channel — maximum bandwidth configuration for storage-intensive workloads requiring high DRAM throughput for large sequential read buffers and write coalescing in HDD array scenarios
DDR4 2666 MT/s (Two DIMMs Per Channel) — Two RDIMMs per channel reduces speed to 2666 MT/s per the memory topology; still sufficient for data-centric storage workloads; also supported with 1st Gen Xeon Scalable which caps at 2666 MT/s in all configurations regardless of DIMM count per channel
Memory RAS: Mirroring and Demand/Patrol Scrubbing — Memory Mirroring creates a redundant in-socket copy of all memory writes for continuous operation on primary DIMM failure; Demand Scrubbing corrects errors back to memory on detected ECC events; Patrol Scrubbing proactively traverses all memory pages to correct multi-bit errors before they escalate to uncorrectable events
SDDC (Single Device Data Correction) — SDDC logic corrects arbitrary failures from any single DRAM chip on a DIMM — including full-chip multi-bit failures across an entire x4 SDRAM device; critical for 24-bay storage servers running RAID rebuilds where concurrent memory errors and drive rebuild operations represent the highest-risk system health event
Memory Population Order — Primary slot A1 on CPU1 must be populated first; CPU2 mirrors CPU1 population for balanced bandwidth; mixed capacities allowed (max two different capacity DIMMs per system) with the larger capacity DIMM filling the first slot; mixing ranks (single rank, dual rank) allowed up to a maximum of two different rank configurations per system
Dual Sliding-Bay Backplane — Up to 24 × 3.5-Inch Hot-Plug Drives Front-Accessible
Two Independent 12-Drive Bays — The R740xd2 chassis is built around two physically separate 12-drive SAS expander backplanes; Bay 1 holds drives 0–11 and Bay 2 holds drives 12–23; both bays slide forward together to expose all 24 front drives simultaneously — enabling full drive population service without removing the R740xd2 from the rack
Config 0 — 24 × 3.5-Inch (Single PERC, No Rear) — All 24 front drives on one PERC controller via the SAS expander daisy chain; no rear drives installed; frees all rear PCIe riser slots for maximum PCIe expansion; preferred for deployments requiring full PCIe card flexibility alongside maximum raw storage capacity in 2U
Config 1 — 24 + 2 × 3.5-Inch (Single PERC, All Drives) — All 24 front + 2 rear 3.5-inch drives under one H740P controller for a single unified 26-drive RAID pool; maximum total capacity at 26 × 16 TB = 416 TB raw; the SAS expander chain routes both front backplanes and the rear cage through the single internal PERC connector
Config 2 — 24 Front + 2 Rear SATA (PERC + Direct SATA) — Front 24 drives managed by PERC (H330/H730P/H740P) via SAS expander; rear 2 drives connect directly to PCH onboard SATA ports for independent boot volume or high-tier SSD cache; 2.5-inch SATA SSDs in 3.5-inch carriers supported in rear positions for tiered storage architectures
Config 3 — Dual PERC (12+12 Independent Domains) — Bay 1 connects to one PERC and Bay 2 connects to a second PERC adapter; each PERC controller independently manages one 12-drive RAID domain; provides data isolation between two storage tenants, simplifies independent RAID rebuild management, and allows different RAID levels optimized for each backplane's workload
Max 384 TB Raw (24 × 3.5-Inch @ 16 TB) — 24 × 16 TB SATA 7.2K NL drives deliver 384 TB raw capacity in a single 2U chassis footprint; with RAID 60 (4+2 stripe set × 2) this provides 256 TB usable at balanced redundancy; with RAID 6, a 24-drive RAID 6 yields approximately 338 TB usable with two simultaneous drive failure tolerance
Mixed 3.5-Inch and 2.5-Inch Hybrid Configuration — Up to 16 × 3.5-inch SAS/SATA front (slots 0–15) plus up to 8 × 2.5-inch SAS/SATA SSD (slots 16–23, must start from slot 23 backward) using 2.5-in-3.5-inch drive adapters; the hybrid config enables a tiered front array with NL-SAS capacity drives alongside 2.5-inch SAS or SATA SSD performance add-on slots within the same 24-bay chassis
3.5-Inch SAS/SATA Nearline, Plus 2.5-Inch SAS and SATA SSD Options
3.5-Inch SATA 7.2K NL Drives — Dell-certified 7.2K RPM SATA 7.2K drives in capacities from 1 TB to 16 TB; 16 TB 7.2K SATA NL drives achieve 384 TB raw at 24-bay full population; per-drive sequential throughput of 200–240 MB/s provides 4.8–5.7 GB/s aggregate front-backplane read bandwidth across all 24 drives simultaneously
3.5-Inch SAS 12 Gbps 7.2K NL Drives — NL-SAS 7.2K drives from 1 TB to 12 TB (native 3.5-inch); dual-port SAS provides two independent SAS paths per drive for redundant path failover when H740P JBOD or RAID with multipath is configured; SAS NL drives carry FIPS 140-2 SED variants (4 TB and 8 TB) for cryptographic at-rest protection on all 24 front bay drives
2.5-Inch SAS SSD in 3.5-Inch Carrier — 2.5-inch SAS SSDs (400 GB–7.68 TB) installed in 3.5-inch drive adapters occupy slots 16–23 (starting from slot 23 backward); mixed spindle + SSD front configuration enables application-tier fast access on SSD slots while bulk cold data resides on NL-SAS or SATA spindle drives in the same backplane
2.5-Inch SATA SSD 6 Gb and 12 Gb Options — SATA 6 Gbps SSD: 240 GB to 1.92 TB capacities; SATA 12 Gbps SSD: 400 GB to 7.68 TB including 1.92 TB SED FIPS variant; SATA SSDs in 3.5-inch adapters for hybrid array configurations where cost and capacity of SATA match requirements better than SAS SSD premium pricing
All Drives Are Hot-Plug — Every front drive bay (0–23) is hot-plug capable with slide-in carrier latches and LED activity indicators; online RAID rebuild begins automatically when a replacement drive is inserted while the remaining drives continue serving I/O; no planned downtime required for drive replacement in RAID 5/6/10 and RAID 50/60 configurations
SED FIPS Drive Options — SED FIPS 140-2 variants available for 3.5-inch SATA (4 TB, 8 TB, 12 TB) and 2.5-inch SAS (1.92 TB) and 2.5-inch SATA SSD (1.92 TB); SED drives enable instant cryptographic erase (ICE) via PERC key management — sanitizing all 24 drives in seconds instead of overwrite-based erase that could take days on multi-terabyte spindle media
Drive Adapter Compatibility — 3.5-inch drive adapters for 2.5-inch SAS/SATA drives use tool-less snap-in or screw-mount variants; carriers from previous-generation PowerEdge servers are not supported — use only Gen 14-certified carrier and adapter combinations to ensure proper backplane connector mating and thermal compliance in the R740xd2 chassis
Up to 2 × 3.5-Inch or 2 × 2.5-Inch Rear Hot-Plug Drives
2 × 3.5-Inch Rear SATA/SAS Drives (Slots 24–25) — Optional rear drive cage adds two 3.5-inch SAS or SATA drives accessible from the back of the chassis without opening the front bays; maximum 32 TB raw rear capacity at 2 × 16 TB; rear drives join the front 24-bay SAS expander domain under the primary PERC controller in Config 1 for up to 26 total drives
2 × 2.5-Inch Rear Drives (15.36 TB Max) — Alternative rear configuration with two 2.5-inch SAS/SATA drives in 3.5-inch carriers in the rear cage; maximum 15.36 TB (2 × 7.68 TB SAS SSD) for rear positions; 2.5-inch SAS SSDs in rear positions serve as a high-performance boot mirror, write journal, or application cache tier kept separate from the bulk 24-bay front storage domain
SATA PCH Direct Connection (Config 2) — The two rear drive bays optionally connect to the onboard PCH SATA ports independently of the PERC controller; in Config 2 mode, rear drives become SATA drives directly attached to the chipset outside the PERC domain, enabling software RAID (S140) or plain AHCI for OS boot volumes while the front 24 bays remain under Hardware RAID management
Dual PERC Config 3 — Independent Rear Domain — In Config 3, the rear 2 drives can be assigned to the second PERC controller as their own RAID domain separate from both front 12-drive backplanes; a second adapter PERC in a PCIe slot manages the rear drives for OS mirroring, boot volume redundancy, or a separate write-hotspot tier for high-write applications
Rear Drive Cage Riser Compatibility — The rear drive cage occupies part of the rear PCIe panel area; not compatible with the Butterfly riser or the maximum PCIe configuration (Butterfly riser + 3 LP cards) — the rear drive cage installation requires the configuration to use either Low-Profile risers only or the single Full-Height riser option to leave physical room for the rear cage hardware
Hot-Plug Accessible from Rear Panel — Both rear drives are individually hot-plug slidable from the rear of the chassis; pressing the carrier release tab allows carrier removal without disrupting the front drives, front backplane power, or active RAID I/O on the remaining 24 front drives — essential for rear RAID 1 mirror replacement during production write operations
SED FIPS Available in Rear Positions — 2.5-inch SATA SED FIPS 1.92 TB variants installable in 3.5-inch adapters in either rear slot; SED encryption at rear positions enables full-chassis drive-level crypto erase of boot and supplementary drives alongside front-bay SED drives for complete cryptographic decommissioning in a single iDRAC Secure Erase operation
PERC H740P, H730P, H330, HBA330, S140, and External H840
PERC H740P (Recommended for R740xd2) — 12 Gbps SAS/SATA hardware RAID with 8 GB NV cache for RAID 0/1/5/6/10/50/60; designed for the R740xd2's SAS expander environment spanning up to 24+2 drives across the dual backplane chain; 8 GB NV cache for write-back caching reduces latency spikes during RAID 6 write parity calculations on spindle drives
PERC H730P — 12 Gbps SAS/SATA hardware RAID with 2 GB NV cache for RAID 0/1/5/6/10/50/60; H730P mini-mono installs in the dedicated internal PERC riser slot; appropriate for single-bay front-only configurations (Config 0) where full SAS expander domain management with 8 GB cache from H740P is not required for the workload's write pattern
PERC H330 — Hardware RAID H330 (no NV cache) at 12 Gbps for RAID 0/1/5/6/10/50/60; lower cost entry parity RAID tier for batch-ingest workloads where NV cache write-back performance is less important than raw sequential write throughput across all 24 spindle drives — suitable for write-once archival storage servers
HBA330 (Non-RAID JBOD Pass-Through) — Internal 12 Gbps SAS HBA mini-mono for direct JBOD pass-through of all 24 front and 2 rear drives to the operating system; required for software-defined storage platforms (Ceph, Gluster, ZFS on Linux) that directly manage drive path access for redundancy without a hardware RAID abstraction layer
S140 Software RAID (SATA Only) — Intel chipset SATA software RAID using CPU-based parity calculation for RAID 0/1/5/10 on SATA and SATA SSD drives; S140 eliminates controller cost for entry SATA-only deployments; CPU overhead for RAID 6 parity on 24 spindle drives is manageable on dual Xeon Scalable CPUs with SATA sequential workloads at moderate queue depths
Dual-Controller Config 3 — Independent PERC Domains — Config 3 places each 12-drive bay under its own PERC controller (Bay 1 → mini PERC internal slot; Bay 2 → adapter PERC in PCIe slot); both RAID domains operate independently — a Bay 2 RAID rebuild on H730P does not impact Bay 1 RAID I/O on the primary H740P, enabling fault-isolated storage tenancy within a single chassis
External Controllers: H840 and 12Gbps SAS HBA — PERC H840 connects the R740xd2 to external 12Gbps PowerVault MD-series JBODs for capacity expansion beyond the 26 internal bays; the 12 Gbps SAS HBA connects to the same external JBOD expansion for non-RAID SAS fabrics; HBA355e provides additional external SAS HBA option for SAS tape library and SAN fabric environments
BOSS M.2 SATA HWRAID 1 and IDSDM MicroSD — Boot Without Sacrificing Drive Bays
BOSS-S1 Card — 2 × M.2 SATA HWRAID 1 — The Boot Optimized Storage Subsystem (BOSS) card is a PCIe card located at the rear of the R740xd2 supporting two 80 mm or 110 mm M.2 SATA or PCIe x1 SSDs in HWRAID 1; available in 240 GB or 480 GB M.2 SATA configurations; BOSS boot keeps the R740xd2's full 24 or 26 hot-plug front/rear bays exclusively for workload storage
BOSS for Full OS Boot — When the target OS is a full OS (Windows Server, Linux, Ceph, or Proxmox) rather than a thin hypervisor, BOSS provides a RAID 1 hardware boot volume without competing with the data RAID domains for drive slots; particularly important on the R740xd2 where every 3.5-inch front bay is valuable for the primary storage application
BOSS for HBA Pass-Through Configurations — When the data drives are managed by HBA330 in JBOD pass-through mode for Ceph or Gluster, BOSS provides the separate dedicated hardware RAID boot mirror without requiring any drive bays; BOSS + HBA330 is the recommended R740xd2 config for Ceph OSD nodes where all 24 bays must be available to Ceph as raw block devices
IDSDM — Internal Dual SD Module (MicroSD) — The combined IDSDM + vFlash card installs in a dedicated Dell-proprietary PCIe x1 slot using a USB 3.0 host interface; supports dual 16/32/64 GB microSD cards in IDSDM mirror mode (IDSDM requires iDRAC Enterprise license); provides a non-drive-bay hypervisor boot volume for VMware ESXi 7.x and 8.x using the OSA-on-SD model
vFlash Module — 16 GB — The combined vFlash and IDSDM card provides a 16 GB vFlash partition alongside IDSDM; vFlash stores iDRAC Virtual Media ISO images, diagnostic scripts, and one-time firmware update packages for use during maintenance windows without requiring network-attached storage for iDRAC Virtual Media operations
IDSDM Only Mode — IDSDM-only operation (no vFlash) is available with the combined card; requires iDRAC Enterprise license to enable the IDSDM mirroring feature; the second microSD card acts as a transparent mirror that iDRAC manages independently — if one microSD fails or shows elevated error rates, iDRAC alerts and the mirror continues from the surviving card
BOSS vs IDSDM Selection — BOSS: recommended for full OS deployments, dual M.2 SSD hardware RAID 1, no iDRAC license dependency, higher capacity than microSD, supports full OS including storage management agents; IDSDM microSD: recommended for thin hypervisor (ESXi) where OSA boot images are compact, and the iDRAC Enterprise license is already purchased for management features
Up to 5 PCIe Gen 3 Slots — Butterfly, Full-Height, Low-Profile, and No-Riser Options
Maximum Configuration — Butterfly Riser + 3 Low-Profile Slots — The Butterfly riser provides Slot 2 (full-height) and Slot 3 (low-profile) for 2 riser-connected cards; Slots 4, 5, and 6 are three fixed low-profile PCIe card slots directly on the rear panel; total of 5 PCIe slots in the maximum configuration (without rear drive cage)
Butterfly Riser — Slot 2 (x8/x16) Full-Height + Slot 3 (x8) LP — The Butterfly riser provides one full-height full-length Slot 2 (PCIe Gen3 x8 or x16 bandwidth) from CPU1 for high-bandwidth cards (25GbE HCA, HBA, PCIe SSD card) and one low-profile Slot 3 (PCIe Gen3 x8 from CPU1) for additional LP NIC, HBA, or management card — both on CPU1 PCIe lanes for direct access
Full-Height Riser — Slot 2 Only — Single full-height riser card provides one FH/FL PCIe Gen3 x8 (or x16) Slot 2 from CPU1; replaces the Butterfly riser when one large single-width PCIe card is required at FH form factor only; compatible with rear drive cage installation (rear 2 drives) unlike the Butterfly riser which requires the rear PCIe area
Low-Profile Riser Pair — Slot 2 + Slot 3 (2 × LP) — Two independent low-profile risers each provide one PCIe Gen3 LP slot from CPU1 (Slot 2) and CPU2 (Slot 3 from CPU2 via left riser); both slots are accessible with rear drive cage installation; ideal for dual LC card configurations (two LP HBAs or LP NICs)
Slots 4, 5, 6 — Fixed LP from PCH and CPU — Slot 6: PCIe Gen3 x4 from PCH (lowest bandwidth, suitable for RAID battery, iDRAC module, or LP management cards); Slot 5: PCIe Gen3 x4 from CPU1 for LP NIC or LP HBA; Slot 4: PCIe Gen3 x16 from CPU2 (highest on-board bandwidth LP slot, suitable for LP 25GbE NIC or LP InfiniBand cable)
No-Riser Configuration — 3 LP Slots Only — Without any riser installed, only Slots 4, 5, and 6 (all LP) are available on the rear panel; the Slot 2/3 riser area is empty; used for configurations requiring only built-in rNDC networking and internal PERC without any additional PCIe cards, or where the rear drive cage occupies that rear panel space
Internal PERC Slot (PCIe Gen3 x8 from CPU1) — The dedicated internal PERC riser slot connects the H740P/H730P/H330/HBA330 to the dual 12-drive backplane SAS expander chain; this slot is separate from the rear-panel expansion slots and does not consume a general-purpose PCIe slot regardless of which storage controller is installed
rNDC Up to 2 × 25GbE SFP28 — iDRAC9 Dedicated 1GbE Out-of-Band Port
2 × 1GbE LOM NDC — Two-port 1 Gigabit Ethernet LOM riser for standard management and host access; occupies LOM Slot 1 (PCIe x8 from CPU1) on the LOM riser connector without consuming a general-purpose PCIe slot; suitable for low-bandwidth management networks and basic iSCSI target configurations
2 × 10GbE NDC — Dual 10 Gigabit BaseT or SFP+ NDC card for primary data center connectivity; supports iSCSI storage access, NFS traffic, and Samba/CIFS file access over the same 10GbE physical links using VLAN tagging; sufficient for most 24-bay bulk storage node applications where aggregate sequential drive bandwidth (typically 3–6 GB/s) stays within 10GbE transport capacity
2 × 10GbE SFP+ NDC — Dedicated SFP+ form factor for twinax DAC or fiber LC connections; lower power and lower latency vs BaseT 10GbE for storage network environments where end-to-end SFP+ fabric is preferred for consistent 10GbE iperf latency profiles
2 × 25GbE SFP28 NDC — Dual 25 Gigabit SFP28 NDC for maximum built-in throughput; 25GbE ×2 = 50 Gbps combined port speed — matching or exceeding the aggregate sequential read bandwidth of a fully-populated 24-bay NL-SAS or SATA HDD array; ideal for high-throughput shared NAS gateway nodes serving multiple compute clients simultaneously
iDRAC9 Dedicated 1GbE Management NIC — Independent out-of-band management NIC on its own power rail; accessible even during OS crashes, network saturation, and power cycling; provides KVM console over IP, virtual media mount for OS recovery, RESTful API inventory, RACADM CLI access, drive health monitoring, and PSU status — all without depending on host OS or data NIC availability
PCIe Add-In NIC Options — Up to 5 PCIe card slots support add-in NICs; 25GbE LP RDMA NIC in Slot 4 (x16 from CPU2) for NVMe-oF initiator or iSCSI/FCoE with RDMA offload; 10GbE LP NIC in Slot 5 for a secondary management VLAN; InfiniBand HDR100 LP adapter for HPC storage fabric access alongside the R740xd2's bulk local storage
NIC Partitioning (NPAR) — Select 10GbE and 25GbE NDC options support NPAR to partition each physical port into up to eight logical bandwidth-guaranteed interfaces; useful for VMware ESXi hosts where storage (iSCSI, NFS), VM data, vMotion, and management traffic must be isolated on separate logical interfaces sharing the physical 25GbE port pair
Hot-Plug Redundant PSUs — 750 W and 1100 W Platinum Efficiency
1+1 Hot-Plug Redundancy — Two hot-swappable PSU bays at the rear of the R740xd2 with full 1+1 redundancy; online PSU swap replaces a failed or degraded PSU without powering down the chassis during active RAID rebuild operations — critical when the system is running a 24-drive RAID 6 rebuild that could take hours and must not be interrupted
750 W Platinum AC (115/230 V) — 80 PLUS Platinum certified at 10%/20%/50%/100% load: 82%/90%/94%/91% efficiency; auto-sensing 115 V and 230 V input for global deployment compatibility; rated for 2891 BTU/hr max heat dissipation; matched to single-CPU or low-populated dual-CPU R740xd2 configurations with spindle-only drives
750 W Mixed Mode Platinum (AC+DC) — 100–240 V AC and 240 V DC auto-ranging on the same PSU unit; intended primarily for China datacenter deployments with 240 V DC UPS infrastructure but also works in any standard 100–240 V AC facility; rated at 2902 BTU/hr; HVDC variant for China 240 V DC-only bus infrastructure
1100 W Platinum AC (115/230 V) — Required for fully-populated dual-CPU configurations with 24 front drives plus 2 rear drives simultaneously spinning; 80 PLUS Platinum certified 89%/93%/94.5%/92% at 10%/20%/50%/100%; rated 4100 BTU/hr max; provides 350 W headroom above maximum dual-CPU + 26-drive peak power for safe bursting
1100 W HVDC (380 V DC) — For 380 V DC HVDC bus data centers; eliminates the AC-to-DC rectification stage in PSU for improved total facility PUE; Platinum efficiency class; available in China/Japan high-voltage DC infrastructure environments where 380 V DC busways replace conventional UPS and AC PDU distribution for data center power chains
PSU Wattage Mismatch Protection — If two PSUs of different wattages are installed (e.g., one 750 W and one 1100 W), the larger PSU powers the system and iDRAC logs a PSU mismatch warning to BIOS event log, iDRAC alert, and optional LCD panel message; the lower-wattage PSU cannot be enabled until matched; prevents accidental degraded-redundancy operation
Energy Smart Adaptive Efficiency — Dell EMC Energy Smart PSUs dynamically optimize efficiency based on real-time load percentage to keep efficiency above 90% across common server utilization ranges (20–80%); combined with iDRAC9 Dell Active Power Controller (DAPC) fan speed management, total system power is minimized at all drive population and CPU TDP combinations
Six Hot-Plug N+1 Fans — Open and Closed Loop Thermal Control
Six Hot-Plug Cooling Fans with N+1 Redundancy — The R740xd2 chassis holds six hot-plug cooling fans; N+1 redundancy means the system continues operating under normal thermal load with one fan failed; iDRAC9 increases remaining fan speeds to maintain all component thermal margins until the failed fan is replaced during normal operation
Standard Operating Range 10–30°C — Inlet temperatures from 10°C (50°F) to 30°C (86°F) with full component support; optimized for standard data center environments with CRAC/CRAH cooling systems maintaining inlet air within this range; extended ambient temperature ranges are documented in the R740xd2 technical specifications supplement at dell.com/support
Open Loop Fan Speed Tables — BOM-based open-loop fan control sets initial fan speeds based on chassis inventory (CPU TDP, drive count, PCIe cards, PSU capacity) and inlet temperature measured at the fan intake; provides stable baseline fan RPM at system startup before sensor feedback loops converge to steady-state closed-loop control
Closed Loop Sensor-Based Control — Continuous feedback from temperature sensors across CPU packages, memory DIMMs, PCH, inlet air, HDD drive temperature data from S.M.A.R.T., and exhaust plenum drives real-time fan speed adjustments to the minimum RPM satisfying all thermal margins simultaneously across all 26 potential drive positions and both CPU sockets
HDD Thermal Throttling Protection — Memory-DDR thermal throttling and HDD over-temperature protection engage before component damage thresholds; iDRAC9 monitors drive S.M.A.R.T. temperature data for all 24+ front bays and alerts when individual drive operating temperature trends toward the manufacturer's max rating — critical for 3.5-inch NL-SAS drives with 60°C typical max operating temperature
Air Shroud Mandatory — The air shroud channels front-to-rear airflow across CPUs and memory DIMMs; never operate R740xd2 with the air shroud removed — overheating and system shutdown will occur within minutes; the R740xd2 uses a separate alternative air shroud variant for configurations with the rear drive cage installed that redirects airflow to clear the rear cage mounting bracket
Dell EMC Acoustical Design — Dell EMC engineering balances sound power level, sound pressure level, and psychoacoustical tone quality to minimize disturbing tonal components across all fan operating speed ranges; standard operating point (20–50% load, ambient 25°C) at typical data center monitoring distances falls within the 35–45 dBA equivalent range comparable to a quiet office background
Front USB 2.0, iDRAC Direct, Right Control Panel VGA — Dual USB 3.0 Rear
Front USB 2.0 — One USB 2.0 port on the right control panel at the front panel; used for OS installation USB drives, field service flash drives, and diagnostic media without accessing the chassis rear; the R740xd2 right control panel includes the USB port flush with the drive bay bezel area for direct front access in fully-racked deployments
Front iDRAC Direct (Micro USB 2.0) — Micro USB 2.0-compliant port on the right control panel for laptop-to-iDRAC9 direct connection without network infrastructure; the iDRAC LED indicator nearby illuminates blue when an active iDRAC Direct session is connected — useful for initial network configuration and field troubleshooting in front-access storage rack environments
Front VGA (Embedded in BMC) — The R740xd2 uses Matrox G200eW3 integrated graphics controller embedded in the BMC (baseboard management controller) with 16 MB video frame buffer; the front VGA port provides POST, BIOS, and OS console output supporting resolutions up to 1920 × 1200 in reduced blanking mode
Internal USB 3.0 — One internal USB 3.0-compliant port on the system board supports an optional USB key for hypervisor boot images, OS installation files, or firmware update packages stored internally without occupying a drive bay or rear panel external slot; the internal USB key persists between chassis open/close service events
Rear USB 3.0 × 2 — Two SuperSpeed USB 3.0 (5 Gbps) ports on the rear panel for external storage devices, long-term USB key mounts, KVM extender adapters, and external USB-to-serial adapters; rear USB 3.0 bandwidth sufficient for external USB 3.0 SSD backup devices during scheduled off-hours backup windows
Rear VGA, DB-9 Serial, and iDRAC9 NIC — 1 × standard 15-pin rear VGA port for alternate rear console access; 1 × DB-9 RS-232 serial connector for Serial-over-LAN relay through iDRAC9 console redirect, out-of-band serial management, and legacy serial console attachment; 1 × iDRAC9 dedicated 1GbE RJ-45 port for management network physical isolation from host data vlans
No Internal Optical Drive (External USB Only) — The R740xd2 does not include an internal optical bay; OS installation and firmware updates via optical media require an external USB DVD-ROM drive; primary recommended install paths are iDRAC virtual media, Lifecycle Controller PXE, USB boot from ISO, or Dell EMC OpenManage Deployment Toolkit to avoid dependency on any physical optical media
TPM 1.2/2.0, UEFI Secure Boot, Signed Firmware, Chassis Intrusion, and Secure Erase
TPM 1.2 and 2.0 Module Options — Plugin Trusted Platform Module (TPM) 1.2 or 2.0 provides hardware-rooted key storage for BitLocker volume encryption on all 24 data drives, platform attestation, Intel TXT Measured Launch, and vTPM for VMs running under Hyper-V or ESXi; TPM 2.0 is required for Windows Server 2022 security baseline compliance and Credential Guard
UEFI Secure Boot — Validates EFI bootloader and OS module signatures before execution, preventing rootkit persistence and unauthorized OS loading from modified boot media; mandatory for NSA CIS Level 2 and NIST SP 800-53 control implementations on R740xd2 nodes in regulated environments handling classified or PII data on its 24 storage bays
Signed Firmware Chain — BIOS, iDRAC9, PERC H740P/H730P/H330, NDC, and PSU firmware packages all carry Dell-signed certificate chains; Lifecycle Controller validates signatures at firmware update installation time and rejects any unsigned, modified, or counterfeit firmware package in any component of the server stack
iDRAC9 Secure Password and Access Control — Default secure password printed on the iDRAC MAC address and secure password label on the information tag; LDAP and Active Directory authentication integration for multi-admin iDRAC access policies; iDRAC role-based access control separates Operator, Readonly, and Administrator permissions for secure ops/admin delegation
Chassis Intrusion Detection Switch — The R740xd2 includes a hardware chassis intrusion switch that signals iDRAC9 when the system cover is removed; iDRAC logs the intrusion event with timestamp and can send an email or SNMP alert to the NOC team; critical for co-location environments where unauthorized physical access to the chassis must be detected and audited
Drive-Level SED FIPS Encryption — Self-Encrypting Drive (SED) variants across 3.5-inch SATA and 2.5-inch SAS/SATA drives provide FIPS 140-2 certified hardware-level AES-256 encryption transparent to the OS and applications; PERC H740P manages SED key authentication and provides instant cryptographic erase of individual drives or all 24 drive bays simultaneously for end-of-life chassis repurposing
Lifecycle Controller System Erase — NIST 800-88-compliant multi-pass overwrite and/or cryptographic erase for all storage media including SAS/SATA HDDs, SATA SSDs, M.2 BOSS devices, IDSDM microSD, and internal USB keys; single-command full-chassis storage sanitization from iDRAC9 reduces decommissioning time for 24-bay R740xd2 nodes from days to under an hour
iDRAC9 with Lifecycle Controller, Redfish API, Ansible Modules, and OpenManage Enterprise
iDRAC9 Embedded Controller — Reports health state for all 26 drive bays, dual backplane SAS expanders, 6 fans, dual PSUs, 16 DIMMs, both CPUs, PCH, and all PCIe slots continuously; manages all drive bay LED activity indicators and enclosure LEDs; sends proactive S.M.A.R.T.-based predictive failure alerts for spindle drive wear before RAID array integrity is compromised
iDRAC9 with Lifecycle Controller — Agent-free out-of-band provisioning and firmware lifecycle management independent of installed OS; Lifecycle Controller handles RAID volume creation across both 12-drive backplanes, firmware baseline comparison and update, OS deployment via PXE or iDRAC virtual media, and full hardware inventory for zero-touch initial R740xd2 configuration
RESTful API with DMTF Redfish — Redfish 1.0-compliant JSON REST API provides programmatic access to storage health, drive S.M.A.R.T. data, RAID volume management, firmware inventory, power metrics, and system health across all R740xd2 nodes in the fleet without installing any host-side OS agent; fully compatible with Ansible, Terraform, Python, and PowerShell management automation frameworks
OpenManage Ansible Modules — Dell EMC OpenManage Ansible Modules provide purpose-built Ansible roles for iDRAC BIOS configuration, firmware update orchestration, RAID volume provisioning, OS deployment, and lifecycle management across R740xd2 fleet clusters; available on Ansible Galaxy and GitHub for integration with existing infrastructure-as-code playbooks
OpenManage Enterprise Console — One-to-many lifecycle management dashboard for all R740xd2 nodes: unified health monitoring, automated firmware compliance baseline with policy-based deviation alerts, power consumption aggregation across rack rows, and automated alert escalation to ServiceNow or other ITSM tools via the OpenManage Integration for ServiceNow (OMISNOW)
OpenManage Integration for VMware vCenter (OMIVV) — Surfaces R740xd2 hardware health, drive status, fan alerts, and firmware compliance status directly inside the vSphere web client alongside VM and datastore performance metrics; enables single-pane VM operations and hardware health monitoring without context switching between vCenter and OpenManage Enterprise for ESXi host management
RACADM CLI and Intel QAT License — RACADM (Remote Access Controller Admin) CLI provides scripted iDRAC configuration and firmware update automation from any management station; Intel Quick Assist Technology (QAT) hardware accelerated compression and cryptography is supported via optional iDRAC license key, enabling transparent hardware crypto offload on the R740xd2 for AES-256 TLS inspection and data compression pipelines
VMware ESXi, Windows Server, RHEL, SLES, Ubuntu LTS, Oracle Linux, and Citrix
VMware ESXi — vSAN and NFSD Ready — VMware HCG certified for R740xd2 with IDSDM microSD OSA boot; OMIVV surfaces R740xd2 hardware health in vSphere; vSAN configurations using HBA330 JBOD pass-through, B160i software RAID, or H740P RAID disk groups; iDRAC Service Module ensures hardware health events propagate to vSphere HA and DRS policies for VM restart-on-host-failure decisions
Windows Server 2019 / 2016 LTSC with Hyper-V — Full Hyper-V host certification with Storage Spaces Direct (S2D) for hyper-converged Windows deployments on R740xd2 nodes; iDRAC Service Module (iSM) passes hardware health data into Windows Performance Monitor and Event Log without external plugin; Storage Replica available for synchronous replication of R740xd2 RAID volumes to a second site
Red Hat Enterprise Linux — Including Ceph — RHEL 7 and 8 certified on R740xd2 with all supported controller configurations; Red Hat Ceph Storage OSD daemon deployment on R740xd2 with HBA330 JBOD mode is a validated reference architecture; OpenShift bare-metal worker node support for containerized data pipeline workloads using R740xd2 local PVs for persistent storage
SUSE Linux Enterprise Server (SLES) — SLES certified including SLES for SAP Applications; SUSE Enterprise Storage (based on Ceph) deployment on R740xd2 nodes with HBA330 or H740P; openSUSE Leap upstream also functions but SUSE SLES with Long-Term Service Pack Support (LTSS) is recommended for production R740xd2 storage appliance deployments requiring multi-year patching continuity
Canonical Ubuntu Server LTS — Ubuntu LTS 20.04 and 22.04 certified for Ceph cluster OSD nodes, OpenStack Cinder + Swift object storage, Kubernetes bare-metal PV nodes, and NFS/SMB server gateways; canonical-upstream k8s + Ceph integration well-validated on R740xd2 hardware for cloud-native on-premises storage platform deployments
Citrix Hypervisor (XenServer) — Citrix Hypervisor certified for VDI hosting server roles; the R740xd2's large SATA/SAS storage capacity enables local persistent VDI desktop storage across up to 24 drives for cost-reduced VDI architectures that avoid all-flash shared storage arrays by using local RAID tiered storage with NL-SAS data and SSD cache drives in the hybrid front configuration
Dell Certified Driver and Firmware Integration — All supported OS versions receive Dell-certified HBA330, PERC H740P, H730P, and NDC drivers through OS vendor repositories, Windows Update, or Dell Repository Manager update packs; Lifecycle Controller PSBI ISOs include pre-integrated OS drivers for offline single-USB deployment without internet network access at installation time
ReadyRails Sliding and Static Rack Kits — 810 mm Deep Chassis in 2U
2U Standard Rack Profile — 86.8 mm (3.41") height in 2 rack units; 482.0 mm (18.9") full EIA-310 rack width; 810.264 mm (31.9") chassis depth without bezel / 844.826 mm (33.26") with bezel; rack depth requirement is notably deeper than the R740xd at 678.8 mm — verify rack internal depth (≥1000 mm recommended) before specifying for shallow-depth cabinets
ReadyRails Sliding — Drop-In Tool-Less — Tool-less drop-in sliding rail installation in 19-inch square or unthreaded round-hole racks; full extension out-of-rack for drive bay service (both 12-drive bays slide forward as a unit), chassis cover removal, DIMM replacement, PCIe card service, and PSU swap without removing the R740xd2 from the rack; OSHA two-person lift for full-drive-populated chassis
Full-Extension for Dual-Bay Service — The R740xd2's sliding rail full extension is essential for front-bay service: both 12-drive bays must slide forward completely exposing all 24 drive slots; the bay-open position locks in a service position for safe hot-plug drive carrier removal/insertion; CAUTION: bays should not remain in service position longer than 5 minutes due to thermal fan spin-up
Optional Cable Management Arm (CMA) — CMA attaches to the sliding rail rear bracket for managed rear cable routing (PSU cables, VGA, USB, NDC, iDRAC management, PCIe card externals) during full-extension service operations; minimum rack depth for CMA installation exceeds the already-deep 810 mm R740xd2 chassis — minimum 1000 mm usable depth confirmed before ordering CMA
ReadyRails Static Rails — Lower-cost stab-in static rails for 4-post racks without full-extension servicing capability; adjusted range 608–879 mm for square/round/threaded hole racks; minimum 622 mm rack depth; two-person sliding service required for drive or component access on static-railed R740xd2 chassis in active rack deployments
Drive Bay Latch Lock — A physical lock pin above the left release latch secures both front drive bays against accidental opening during transport or in secure co-location environments; the lock prevents both Bay 1 and Bay 2 from sliding forward simultaneously unless unlocked by a keyed operator — important for physical data security compliance in shared rack space
System Weight — The R740xd2 chassis is heavier than the R740xd due to the extended chassis depth and dual 12-drive backplane assembly; maximum populated chassis with 24 × 3.5-inch drives plus rear cage requires a minimum two-person lift per OSHA ergonomics guidelines; disconnect PSUs and remove all drives before single-person rack/un-rack operations where weight exceeds safe single-operator limits
R740xd2 (Gen 14) vs R730xd2 (Gen 13) — Faster Cores, More Memory, 25GbE, and iDRAC9
2nd Gen Xeon Scalable vs Xeon E5-2600 v3/v4 — Cascade Lake-SP (Gen 14) replaces Broadwell/Haswell EP (Gen 13); 50% more memory channels per socket (6 vs 4), Intel UPI replacing QPI for higher inter-CPU bandwidth, AVX-512 replacing AVX-2, and up to 22 cores in the R740xd2 vs limited Broadwell EP core counts — providing faster per-core performance for Ceph OSD, software RAID, and compression workloads
DDR4 2933 MT/s vs DDR4 2133 MT/s Max — R730xd2 maximum DDR4 speed was 2133 MT/s; R740xd2 supports 2666 MT/s default and 2933 MT/s with 2nd Gen Xeon at 1 DPC; 38% memory bandwidth improvement per channel directly benefits data-intensive storage controllers managing high-queue-depth RAID array I/O into DRAM write-back cache before committing to NV cache or spindle drives
24 Front + 2 Rear = 26 Drives vs ~24 Drives (R730xd2) — The R740xd2 targets the same 2U 24-bay front max as the R730xd2, but adds two optional rear bays for 26 total hot-plug drives in the same chassis footprint; the dual 12-drive sliding-bay backplane design is unique to the R740xd2 and was not available in the R730xd2's fixed front backplane design
25GbE NDC Option (New) — The R730xd2 maxed at 10GbE built-in NDC; R740xd2 adds 2 × 25GbE SFP28 NDC option — enabling 50 Gbps combined throughput to match the aggregate sequential read bandwidth of fully populated NL-SAS or SATA arrays serving file server or NAS gateway workloads over fast 25GbE leaf switch fabrics
BOSS M.2 Boot Module (New) — R730xd2 required boot from a front drive bay or IDSDM microSD; R740xd2 adds dedicated BOSS card with 2 × M.2 SATA HWRAID 1 (240/480 GB) preserving all 24 front drive bay slots for workload data; BOSS boot is the primary recommendation for full OS deployments on R740xd2 where every 3.5-inch bay counts
iDRAC9 vs iDRAC8 — iDRAC9 adds Redfish RESTful API, Quick Sync 2 BLE/Wi-Fi (optional), System Erase with NVMe/microSD support, SupportAssist predictive failure AI for all 26 drive bays, RACADM v7 scripting improvements, OpenManage Integration for ServiceNow (OMISNOW), Ansible Modules, and Intel QAT license key enablement — all absent from iDRAC8 in the R730xd2
Lifecycle Controller 3.x vs 2.x — Lifecycle Controller 3.x on Gen 14 adds support for firmware update from the network (no USB required), improved catalog-based firmware compliance management, OS deployment integration with Dell OpenManage Deployment Toolkit, and Redfish-enabled agent-free firmware update APIs compatible with Ansible and cloud-init automation pipelines not available in LC 2.x
