3rd Gen Intel Xeon Scalable — Up to 2 × 24 Cores on PCIe Gen 4
Platform Overview — Dual LGA4189 sockets with Intel C621A chipset; supports one or two 3rd Generation Intel Xeon Scalable processors simultaneously; Intel Ultra Path Interconnect (UPI) provides up to 3 × UPIs per socket at 11.2 GT/s for Gold and Platinum class CPUs — maximum inter-socket bandwidth for dual-NUMA workloads
Top Processor — Xeon Silver 5318Y — 24 cores / 48 threads, 2.1 GHz base, Turbo enabled, 36 MB L3 cache, 11.2 GT/s UPI, 165 W TDP, 2933 MT/s DDR4; maximum available on R450 for highest core density in data warehouse, ERP, and large virtualization deployments
Xeon Silver 5317 — 12 cores / 24 threads, 3.0 GHz base, Turbo enabled, 18 MB L3 cache, 11.2 GT/s UPI, 150 W TDP; balances high per-thread clock speed with moderate core count for latency-sensitive database and application server workloads
Xeon Silver 5315Y — 8 cores / 16 threads, 3.2 GHz base, Turbo enabled, 12 MB L3 cache, 11.2 GT/s UPI, 140 W TDP; highest base clock in the Silver lineup — optimal for single-threaded application performance within a dual-socket deployment
Xeon Gold 4316 — 20 cores / 40 threads, 2.3 GHz base, Turbo enabled, 30 MB L3 cache, 10.4 GT/s UPI, 150 W TDP; supports DDR4 up to 2666 MT/s; best value high-core-count option for mixed virtualization and database environments that can tolerate 10.4 GT/s UPI
Xeon Gold 4314 — 16 cores / 32 threads, 2.4 GHz base, Turbo enabled, 24 MB L3 cache, 10.4 GT/s UPI, 135 W TDP; DDR4 up to 2666 MT/s; strong mid-range compute density for general enterprise application tiers and mid-scale virtualization clusters
Xeon Gold 4310 and 4309Y — 4310: 12 cores / 24 threads, 2.1 GHz base, 18 MB cache, 120 W; 4309Y: 8 cores / 16 threads, 2.8 GHz base, 12 MB cache, 105 W; both at 10.4 GT/s UPI and 2666 MT/s DDR4 — entry Gold options balancing cost and power budget for lighter workloads
PCIe Gen 4 Lanes — 64 PCIe 4.0 lanes per socket at 16 GT/s; each x16 slot delivers 32 GB/s bidirectional bandwidth; dual-socket configuration provides 128 total PCIe Gen 4 lanes — future-ready for high-speed NVMe drives and 25 GbE NICs without bandwidth contention
DDR4 ECC RDIMM — Up to 1 TB Across 16 Slots at 2933 MT/s
Memory Type — DDR4 Registered ECC (RDIMM) only; UDIMMs are not supported; the register buffer in RDIMMs reduces memory bus loading, enabling higher slot counts and larger DIMM capacities essential for the R450's 16-slot, dual-socket memory platform; ECC corrects single-bit errors in real time protecting database and VM workloads
DIMM Slots & Channels — 16 total DIMM slots: 8 per processor in a multi-channel configuration; each processor supports 4 memory channels with 2 DIMMs per channel (2 DPC); populate in matched pairs per channel for maximum bandwidth — dual-socket deployments should mirror DIMM population across both processors for uniform NUMA memory capacity
Maximum Capacity — 1 TB total (1024 GB) when all 16 slots are populated with 64 GB DDR4 RDIMMs; 512 GB with 32 GB DIMMs; 256 GB with 16 GB DIMMs — scale capacity to match the in-memory footprint of the target database, hypervisor, or analytics workload
Supported DIMM Sizes — 8 GB (SR×8), 16 GB (SR×4 or DR×8), 32 GB (DR×8 or DR×4), and 64 GB (DR×4) DDR4 RDIMMs at 1.2 V; 3200 MT/s DIMMs are supported but the maximum operating speed on R450 is 2933 MT/s with Silver processors — processor selection determines actual operating frequency
Memory Speed by Processor — Xeon Silver 5315Y, 5317, and 5318Y processors support DDR4 at 2933 MT/s; Xeon Gold 4309Y, 4310, 4314, and 4316 processors are limited to 2666 MT/s because of their 10.4 GT/s UPI — select a Silver processor when maximizing memory bandwidth for database and analytics workloads
NUMA Architecture — In dual-socket configurations, each processor controls its own 8 DIMM slots forming a local NUMA node; OS and hypervisor memory controllers route threads to local-node memory first; configure VM affinity pinning in VMware or Hyper-V to keep virtual machines on a single NUMA node for predictable latency
Upgrade from R440 — R450's RDIMMs support 64 GB DIMMs for 1 TB total; the R440 also supported RDIMMs but the R450's 3rd Gen Xeon platform offers 2933 MT/s peak versus the R440's 2nd Gen memory ceiling, and the R450 drops NVDIMM support while increasing conventional RDIMM density
4 × LFF or 8 × SFF — Hot-Swap SAS and SATA Up to 64 TB
4 × 3.5-inch LFF Hot-Plug — Four Large Form Factor bays support hot-swap SAS or SATA HDDs and SSDs; maximum raw capacity with four 16 TB SATA HDDs reaches 64 TB; ideal for file storage, backup targets, and capacity-oriented applications where large sequential throughput matters more than drive bay density
8 × 2.5-inch SFF Hot-Plug — Eight Small Form Factor bays support hot-swap SAS/SATA HDDs and SSDs; maximum raw capacity 61.44 TB with SAS SSDs; IOPS-optimized for databases, ERP, and virtualization workloads requiring low-latency random I/O — combine 15K RPM SAS HDDs with SAS SSDs across bays for tiered storage
3.5-inch LFF Drive Options — SATA 6 Gb/s HDDs at 7.2K RPM in 2 TB, 4 TB, 8 TB, 12 TB, and 16 TB capacities; SAS 12 Gb/s HDDs at 7.2K RPM in 2 TB, 4 TB, 8 TB, 12 TB, and 16 TB; choose SAS for dual-path redundancy from the backplane and higher sustained transfer rates on sequential workloads
2.5-inch SFF Drive Options — SAS 10K RPM HDDs (600 GB, 1.2 TB, 2.4 TB); SAS 15K RPM HDDs (900 GB); SAS SSDs at 12 Gb/s (480 GB, 800 GB, 960 GB, 1.6 TB, 1.92 TB, 3.84 TB, 6.4 TB, 7.68 TB); SATA SSDs at 6 Gb/s (480 GB, 960 GB, 1.92 TB, 3.84 TB) — match drive endurance rating to workload write intensity
M.2 SATA Boot Storage — 240 GB and 480 GB M.2 SATA SSDs available for the BOSS-S1 boot module; microSD cards (16 GB, 32 GB, 64 GB) for IDSDM; neither BOSS nor IDSDM competes with data drive bays — OS storage is fully independent of application data storage
External JBOD Expansion — HBA355e external SAS 12 Gb/s host bus adapter connects to MD-Series and ME-Series JBODs for scale-out capacity beyond the internal bays; supports up to 240 drives per HBA through SAS expanders — enables petabyte-scale NAS and archive configurations from a single R450 head node
PERC H755 to S150 — Full RAID Stack with Front PERC Option
PERC H755 (Premium Hardware RAID) — 12 Gb/s SAS controller with NV Flash-Backed write cache on PCIe Gen 4; supports RAID 0, 1, 5, 6, 10, 50, and 60; the NV cache absorbs burst writes and persists data across power failure — essential for database transaction logs, OLTP writes, and write-intensive analytics workloads requiring RAID 6 protection
PERC H745 (Value Performance RAID) — 12 Gb/s SAS controller with write cache on PCIe; supports RAID 0, 1, 5, 6, 10, 50, and 60; mid-tier option between H755 and entry RAID — appropriate for virtualization and database deployments that need RAID 5/6 parity protection with write caching but at a lower cost than H755
PERC H355 Front PERC (Dedicated Front Module) — 12 Gb/s SAS controller in a small form factor installed in the dedicated front PERC slot on the system board; does not consume a PCIe expansion slot; supports RAID 0, 1, and 10 — keeps both PCIe expansion slots free for NIC and other add-in cards in slot-constrained configurations
PERC H345 (Entry Hardware RAID) — 12 Gb/s SAS entry controller on PCIe Gen 4; supports RAID 0, 1, and 10 without write cache; lower-cost alternative to H355/H745/H755 for read-intensive workloads, test and development environments, and configurations where write-back caching is not required
HBA355i (Internal SAS Pass-Through) — 12 Gb/s SAS HBA on PCIe Gen 4 with no RAID; passes drives directly to OS for software RAID, ZFS, or hypervisor-managed storage; up to 16 drives per controller — use when storage virtualization or software-defined storage manages data protection at the hypervisor or OS level
PERC H840 & HBA355e (External) — PERC H840 external RAID connects to MD/ME-Series JBOD enclosures with full RAID 0–60 support; HBA355e provides 12 Gb/s external SAS pass-through to JBODs for OS-managed external storage pools; both options expand capacity beyond internal bay limits without changing the server configuration
PERC S150 (Software RAID) — SATA-only software RAID in firmware supporting RAID 0, 1, 5, and 10; no additional PCIe consumption; lowest-cost storage controller option for non-critical data or test environments where hardware RAID investment is not justified; RAID rebuild I/O runs on the Xeon Scalable processor — avoid on fully loaded systems
BOSS-S1 Mirrored M.2 Boot — Independent of Data Drive Bays
BOSS-S1 Module (Primary Boot Option) — Boot Optimized Storage Solution using dual M.2 SATA SSDs in hardware RAID 1 (mirrored) configuration; the integrated RAID controller maintains a real-time mirror of the OS partition — a single M.2 SSD failure does not interrupt server operation; BOSS mounts in a dedicated integrated slot that does not consume PCIe expansion slots
BOSS-S1 Drive Capacities — M.2 SATA SSDs available in 240 GB and 480 GB; both sizes are rated Read-Intensive (low DWPD) — appropriate for OS boot, hypervisor images, and small application installations with minimal sustained write activity; OS I/O is fully isolated from SAS/SATA data drive traffic
BOSS Riser Integration — The BOSS-S1 module installs via a dedicated riser on the system board; the rear-accessible hot-plug design allows M.2 SSD replacement from the back of the chassis; iDRAC monitors BOSS RAID status and raises alerts on RAID degradation before a second drive failure can cause data loss
IDSDM (Internal Dual SD Module) — Alternative boot option using dual microSD cards in hardware RAID 1 mirror; microSD sizes of 16 GB, 32 GB, and 64 GB; intended for hypervisor boot images (VMware ESXi, Citrix Hypervisor) where the hypervisor vendor supports SD-based deployment and write activity is minimal; I2C monitoring provides individual card health status to iDRAC
Internal USB (Optional) — Optional internal USB 3.0 card (40 × 16 × 8 mm dongle) adds one internal USB 3.0 port inside the chassis; provides persistent in-chassis USB storage, hardware security key, or supplemental boot media without occupying external USB ports or PCIe expansion slots
Boot Device Recommendation — BOSS-S1 is the preferred production boot device for OS and hypervisor deployments; its dedicated M.2 SATA bandwidth is never competing with data drive workloads; IDSDM is suitable for ESXi and Citrix setups where hypervisor write activity to the boot device is minimal — do not use SD cards for guest VM boot or data storage
2 × PCIe Gen 4 Slots — Riser 1 + Riser 2C with Integrated OCP 3.0
Config 0 — Single Riser (R1) — One low-profile half-length PCIe Gen 4 x16 slot via Riser 1 (Slot 1), controlled by Processor 1; single-socket configurations use Config 0 — the single slot accommodates one full-bandwidth NIC, HBA, or PCIe SSD AIC adapter; this configuration keeps the BOSS-S1 integrated boot slot independent
Config 1 — Dual Riser (R1 + R2C) — Two low-profile half-length PCIe Gen 4 x16 slots: Slot 1 via Riser 1 (Processor 1) and Slot 3 via Riser 2C (Processor 2); dual-socket dual-riser configuration enables two independent PCIe devices such as a 25 GbE NIC in Slot 1 and an external SAS HBA in Slot 3 — or two NIC cards for high-throughput network configurations
OCP 3.0 Integrated Slot — One integrated OCP 3.0 NIC slot (PCIe Gen 4 x16) on the system board; supports OCP Small Form Factor cards from Intel, Broadcom, QLogic, and Mellanox at speeds from 1 GbE to 25 GbE; the OCP slot is in addition to the Riser 1 and Riser 2C expansion slots — providing up to 3 high-bandwidth slots total in Config 1
Slot Width — LP HL Only — All expansion slots accommodate low-profile half-length cards only; the 1U chassis depth does not accommodate full-height or half-height full-length cards; verify add-in card dimensions before ordering — this is a 1U constraint that applies to both riser slots
Supported Add-in Cards — 1GbE and 10GbE NIC cards (Broadcom, Intel, QLogic) in Slots 1 and 3; 25 GbE NIC cards (Broadcom, Intel, Mellanox, QLogic, SolarFlare) in Slots 1 and 3; PCIe SSD AICs (Intel, Samsung) in Slots 1 and 3; external PERC adapters in Slots 1 and 3; Dell serial port module in Slot 1
BOSS + Front PERC Slots — The BOSS-S1 module occupies a dedicated integrated BOSS slot independent of riser expansion; the front PERC (H355 fPERC) occupies a dedicated front PERC integrated slot independent of riser expansion — neither boot nor RAID storage controller consumes the Slot 1 or Slot 3 user expansion slots
Dual 1 GbE LOM + OCP 3.0 Up to 25 GbE — PCIe Gen 4 Bandwidth
Embedded Dual-Port 1 GbE LOM — Broadcom BCM5720 integrated dual-port 1 GbE NIC (10/100/1000BASE-T); both ports appear on the rear panel and support Wake-on-LAN, PXE network boot for OS provisioning, and iDRAC Shared LOM — allowing the dedicated iDRAC management port to share one physical 1 GbE port with host OS traffic when a separate management network is not available
Dedicated iDRAC Network Port — A dedicated RJ-45 iDRAC9 management port on the rear panel provides isolated out-of-band connectivity for full remote management independent of LOM data ports; use the dedicated port in Enterprise and Datacenter license tiers to segregate iDRAC traffic from production data traffic on separate management VLANs
OCP 3.0 Slot — Up to 25 GbE — One integrated OCP 3.0 NIC slot on PCIe Gen 4 x16; supports Small Form Factor OCP cards from Intel, Broadcom, QLogic, and Mellanox; available speeds: 1 GbE (BT, 4-port), 10 GbE (BT or SFP+, 2–4 port), and 25 GbE (SFP28, 2–4 port); OCP 3.0 Gen 4 doubles available per-lane bandwidth versus OCP 2.0 Gen 3 on the predecessor R440
10 GbE PCIe Add-in NICs — Additional 10 GbE cards (Intel, Broadcom, QLogic) supported in PCIe Slot 1 and Slot 3 (Config 1 dual riser); with Config 1 and an OCP 10 GbE card, the R450 can run three simultaneous 10 GbE connections — separating iSCSI, NFS, and management traffic across dedicated interfaces
25 GbE Options via OCP and PCIe — Broadcom (SFP28, 2-port and 4-port), Intel (SFP28, 2-port), Mellanox (SFP28, 2-port), QLogic (SFP28, 2-port), and SolarFlare (SFP28) in both OCP 3.0 and PCIe expansion formats; 25 GbE eliminates bandwidth bottlenecks for container overlay networks, iSCSI SANs, and large virtualization clusters
Quick Sync 2 Wireless Module — Optional integrated wireless management module using BLE (Bluetooth Low Energy); enables iDRAC configuration, inventory review, and basic server management from a smartphone running OpenManage Mobile — useful for ROBO and edge deployments where iDRAC network access is not yet established during initial provisioning
600 W to 1100 W — Platinum and Titanium Hot-Swap Redundant PSUs
600 W AC 80 PLUS Platinum — Dual hot-swap PSU bays; 600 W per unit; 80 PLUS Platinum efficiency at 92% (20% load), 94% (50%), 90% (100%); auto-ranging 100–240 V AC / 240 VDC input; suitable for single-socket, light-storage, standard LFF configurations where total system load stays within 600 W per PSU
700 W Mixed Mode 80 PLUS Titanium — Dual hot-swap PSU bays; 700 W per unit at high-line (200–240 V AC / 240 VDC); 80 PLUS Titanium efficiency at 90% (10% load), 94% (20%), 96% (50%), 91% (100%) — highest efficiency available; requires 200 V or higher AC input; not available at 100 V low-line — verify site power before ordering Titanium PSU
800 W AC 80 PLUS Platinum — Dual hot-swap PSU bays; 800 W per unit at both high-line and low-line; Platinum efficiency; recommended for dual-socket medium-configuration deployments with 4–8 drives and OCP NIC add-in cards installed under full load
1100 W Mixed Mode 80 PLUS Titanium — Dual hot-swap PSU bays; 1100 W at high-line, 1050 W at low-line; Titanium efficiency; maximum headroom for dual-socket 185 W TDP processors with fully populated 16 DIMM slots, 8 × 2.5-inch SAS drives, and dual 25 GbE add-in cards simultaneously — ensures PSU does not limit server configuration
1100 W DC (−48 V to −60 V) — Dedicated DC input PSU for data centers using DC power distribution; 1100 W at DC rail; same hot-swap form factor as AC units — enables PSU standardization in mixed AC/DC rack environments without changing the chassis hardware
Redundant Hot-Swap Design — Both PSU bays active simultaneously in 1+1 redundant configuration; the surviving PSU assumes full load instantly on failure; failed unit can be replaced while the server runs; Dell's power monitoring accuracy is 1% versus the 5% industry standard — enabling tighter power capping configurations
Upgrade from R440 — R450 adds 700 W Titanium and 1100 W Titanium PSU options; the R440's maximum was 550 W Platinum — the R450's expanded PSU options provide headroom for dual-socket 165 W TDP CPUs, fully populated memory, and high-bandwidth NIC configurations that exceeded the R440's power budget ceiling
N+1 Fan Redundancy — ASHRAE A2/A3/A4 with STD and HPR Silver Fans
Fan Configuration — Up to seven cold-swap fans in both LFF and SFF chassis configurations; N+1 fan redundancy means the server continues operating if one fan fails — remaining fans increase speed automatically to compensate; fan blanks required in empty slots 1 and 2 (for single-processor configurations) to maintain proper airflow direction through the chassis
Standard vs. High Performance Silver Fans — Standard (STD) fans support configurations up to 165 W TDP per processor; High Performance (HPR) Silver fans are required when installing processors between 165 W and 220 W TDP; the system ships with the fan tier appropriate for the processor ordered — HPR fans replace STD fans as the customer upgrades to higher-TDP processors
Dynamic Thermal Control — Open and closed loop thermal control operates simultaneously; closed loop monitors real-time sensor data from processors, DIMMs, chipset, inlet air, HDDs, OCP NIC temperatures, and individual drive temperatures; open loop uses configuration inventory to pre-determine minimum fan speed; the more aggressive of the two controls actual fan speed at any moment
ASHRAE A2 Standard Operation — Standard operating envelope: 10–35°C (50–95°F) at altitudes below 900 m; maximum operational altitude 3,048 m (10,000 ft) with derating of −1°C per 300 m above 900 m; all CPU options, all drive configurations, and OCP NIC cards supported in A2 environments
ASHRAE A3 Extended Operation (5–40°C) — Extended operating envelope for equipment rooms without precision air conditioning; CPU TDP limited to 150 W maximum; BOSS-S1 M.2 module not supported; PCIe NIC cards drawing ≥25 W not supported in A3 — verify configuration compatibility against Dell thermal restriction tables before A3 deployment
ASHRAE A4 Extended Operation (5–45°C) — High ambient envelope for colocation and telco environments; same restrictions as A3 apply; not all drive and NIC configurations are validated for A4 — consult Dell EMC PowerEdge R450 Technical Specifications for current A4 component compatibility list
Air Cooling Only — The R450 does not support direct liquid cooling or rear-door heat exchanger options; all thermal management is forced-air convection; the 1U chassis design optimizes airflow for standard data center front-to-rear airflow patterns
iDRAC Direct Front Access + Dual VGA + USB 3.0 Rear Panel
Front Panel — iDRAC Direct (Micro-AB USB) — Dedicated iDRAC Direct micro-USB port on the front panel; connect a laptop for direct browser-based iDRAC management at 169.254.0.1 without network access; the iDRAC Direct LED indicates active session state — simplifies on-site BIOS configuration and troubleshooting without needing rear panel access
Front Panel — USB 3.0 — One USB 3.0 Type-A port on the front panel; supports high-speed peripherals, deployment drives, and OS installation media at up to 5 Gb/s; maximum output current 0.9 A — suitable for storage devices but not for high-power USB peripherals
Front Panel — VGA — One VGA display port on the front panel for direct console access; available at the front of the chassis for local keyboard-video-mouse access during provisioning without reaching to the rear panel — a practical advantage for rack-dense deployments where rear access requires rail slide-out
Rear Panel — USB 2.0 and USB 3.0 — One USB 2.0 Type-A and one USB 3.0 Type-A on the rear panel; USB 2.0 (0.5 A max) for KVM dongles and management tools; USB 3.0 (0.9 A max) for external storage, deployment tools, and OS media requiring sustained throughput
Rear Panel — Dual LOM Ethernet + Dedicated iDRAC — Two RJ-45 1 GbE LOM ports for production data traffic; one dedicated RJ-45 iDRAC9 management port for out-of-band management; three rear Ethernet ports total — enables management network isolation from production VLAN without an OCP NIC installed
Rear Panel — VGA + Optional Serial — One VGA port on the rear panel for standard console access; one optional DB-9 serial port for serial console logging, BIOS terminal access, and out-of-band management over serial concentrators — both operate independently of iDRAC and function without network connectivity
Internal USB (Optional) — Optional internal USB 3.0 dongle (40 × 16 × 8 mm) installs inside the chassis; suitable for persistent boot media, hardware security keys, or TPM-adjacent USB devices that must remain physically secured inside the server — does not consume any expansion slot or external port allocation
Silicon Root of Trust — Hardware-Anchored Cyber Resilient Architecture
Silicon Root of Trust — Cryptographic trust anchored in hardware at the silicon level; the iDRAC9 firmware validation chain is tied to immutable keys in the processor silicon before any firmware code executes; tampering with any firmware in the boot chain halts the boot sequence and raises a security alert — a compromised firmware cannot silently persist or disable the security chain
Secured Component Verification — Factory-time cryptographic fingerprinting of components; at first boot iDRAC9 verifies that every installed component matches the factory manifest; unauthorized component substitutions during shipping or storage are detected and logged — provides supply chain integrity assurance before the server enters production
Cryptographically Signed Firmware — Every firmware update package (BIOS, iDRAC, PERC, OCP NIC, and peripheral components) carries a cryptographic digital signature; the system verifies the signature before applying any update; unsigned or tampered firmware packages are rejected regardless of how they were delivered to the system
UEFI Secure Boot — Validates OS bootloader and driver signatures against an authorized database at startup; prevents unsigned or unauthorized operating systems and drivers from loading; critical for environments operating under PCI-DSS, HIPAA, FedRAMP, and DISA STIG compliance frameworks that mandate bootloader integrity validation
System Lockdown — Prevents unauthorized configuration changes to BIOS, iDRAC, and firmware settings when enabled; requires iDRAC9 Enterprise or Datacenter license; all lockdown override attempts are logged in iDRAC event log; a physical system presence check can override lockdown for authorized recovery — limits attack surface for insider threats and misconfiguration
TPM 1.2 / 2.0 and TCM 2.0 — TPM 1.2 and TPM 2.0 supported; FIPS 140-2 certified and CC-TCG (Common Criteria Trusted Computing Group) certified; cryptographically bound to the system board — TPM migration to a different board is blocked by hardware design; TCM 2.0 available for markets requiring Chinese Cryptography Standards compliance
Secure Erase — iDRAC-managed secure wipe for HDDs, SSDs, and system memory in compliance with NIST 800-88 media sanitization guidelines; use before decommissioning, redeployment, or disposal to prevent data recovery from retired R450 components — available regardless of OS state via Lifecycle Controller

iDRAC9 License Tiers — iDRAC9 Express is included on every R450 and provides sensor monitoring, event alerting, and basic remote access; Enterprise adds dedicated NIC isolation, virtual console, virtual media, power capping, System Lockdown, and group management; Datacenter adds telemetry streaming, iDRAC RESTful API scripting extensions, and GPU management hooks
iDRAC Service Module (iSM) — Lightweight in-band agent running inside the OS providing additional inventory and monitoring data to iDRAC; enables in-band management commands without SSH access to iDRAC; iSM is optional and does not require additional license — extends iDRAC visibility into OS-level metrics when installed
Lifecycle Controller — Embedded OS-agnostic provisioning engine; supports bare-metal firmware updates, driver deployment, system inventory, and full OS installation without an existing OS or network-mounted install media; all actions are logged with version history for audit trail and change management purposes
Redfish RESTful API — Full DMTF-standard Redfish API on iDRAC9; enables infrastructure-as-code workflows via curl, Python, Ansible, Terraform, and PowerShell; standard endpoints for provisioning, firmware lifecycle, power management, and sensor polling — integrate with CI/CD pipelines and IaC automation frameworks without proprietary tooling
OpenManage Portfolio — Dell OpenManage Enterprise (OME) provides one-to-many server inventory, firmware management, and alerting across multiple R450 deployments; OpenManage Mobile (OMM) extends smartphone-based management; OpenManage Power Manager plugin provides group power capping and energy analytics across racks
Automation Integrations — Red Hat Ansible Modules for iDRAC enable idempotent playbook-based configuration; OpenManage Integration for VMware vCenter (OMIVV) surfaces Dell firmware management inside vCenter; OpenManage Integration with ServiceNow (OMISNOW) automates incident creation directly from iDRAC hardware alerts into ITSM workflows
Quick Sync 2 Wireless Module — Optional BLE wireless module enables iDRAC configuration and inventory review from OpenManage Mobile on a smartphone; useful for ROBO initial provisioning where LAN access to iDRAC is not yet available during rack deployment — configure IP settings, view hardware inventory, and check alerts wirelessly before cable management is complete
Broad OS Compatibility — Windows Server, Linux, and VMware
Microsoft Windows Server with Hyper-V — Certified for Windows Server production workloads with Hyper-V guest support; Windows WSSD (Windows Server Software-Defined) storage configurations supported over iSCSI and SMB traffic on 10 GbE OCP NIC; dual-socket NUMA topology in Windows Server benefits from vNUMA-aware VM placement in Hyper-V

Citrix Hypervisor — Citrix Hypervisor (formerly Citrix XenServer) certified for virtual desktop infrastructure (VDI) and application delivery workloads; IDSDM microSD boot is supported for Citrix Hypervisor deployments where the hypervisor recommends flash-based boot media
Lifecycle Controller Bare-Metal Deployment — The embedded Lifecycle Controller supports OS installation from embedded driver packs without network-mounted ISO images or PXE infrastructure; supported OS driver packs are embedded in firmware and applied automatically during the guided Lifecycle Controller deployment wizard — simplifies remote site provisioning without a local IT technician
Stab-In Sliding Rails — Tool-Less 4-Post with CMA and Strain Relief Bar
Stab-In / Drop-In Sliding Rails — Primary rack mounting option for both LFF and SFF chassis; tool-less installation in 4-post racks with square or unthreaded round mounting holes including all generations of Dell racks; tool-less support also available for threaded 4-post racks with no conversion hardware required — one rail kit covers all standard 4-post rack types
ReadyRails Static Rails — Fixed static rail option supporting both 4-post racks (tool-less in square/round holes, tooled in threaded) and 2-post relay racks (tooled); 2-post support is unique to static rails — use static rails for telco rack and branch office 2-post IDF deployments where full server slide-out is not required
Cable Management Arm (CMA) — Optional CMA compatible with sliding rails only; mounts tool-less on either the left or right side of the rails (mount opposite the PSU bays for easiest single-PSU access); large U-shaped baskets with open vent pattern and hook-and-loop straps; the CMA unfolds with the server slide-out so rear cables remain connected during drive and PSU service
Strain Relief Bar (SRB) — Optional alternative to CMA; tool-less attachment to the sliding rails; supports two depth positions to accommodate cable loads and varying rack depths; organizes cables into discrete purpose-specific bundles; reduces stress on server rear connectors during maintenance — appropriate when CMA bulk is a concern in dense rack configurations
Chassis Depth Specifications — 4 × 3.5-inch LFF chassis: 712.95 mm (28.07 in) with bezel; 8 × 2.5-inch SFF chassis: 662.19 mm (26.07 in) with bezel; height 42.8 mm (1.7 in) — 1U; width 482 mm (18.98 in); both chassis fit standard ANSI/EIA 19-inch rack enclosures with slide clearance for service access
Cross-Compatibility with R440 Rails — The R450 is compatible with R440, R6515, and R6415 rails and CMA; existing R440 customers upgrading to R450 can reuse installed rail kits without purchasing new rail hardware — verified by Dell Engineering for physical fit and cable management compatibility
R450 vs R440 — Gen 15 Upgrades Across CPU, PCIe, PSU, and Networking
Processor Platform Upgrade — R450 moves from the R440's 2nd Gen Intel Xeon Scalable (Cascade Lake, LGA3647) to 3rd Gen Intel Xeon Scalable (Ice Lake-SP, LGA4189); the new platform delivers improved IPC, PCIe Gen 4 integration, and a 3-port UPI at 11.2 GT/s for Gold/Platinum CPUs versus the R440's 3-port UPI at 10.4 GT/s
PCIe Generation — Gen 4 vs Gen 3 — R450 integrates 64 PCIe Gen 4 lanes per socket (128 total in dual-socket) at 16 GT/s versus the R440's Gen 3 lanes at 8 GT/s per lane; Gen 4 doubles per-lane bandwidth — OCP 3.0 on the R450 uses a full x16 Gen 4 interface versus the R440's OCP 2.0 on Gen 3
OCP Standard — 3.0 Gen 4 vs 2.0 Gen 3 — R450 OCP 3.0 slot supports PCIe Gen 4 x16 with max port speeds up to 100 GbE; R440 OCP 2.0 was limited to Gen 3 x16; OCP 3.0 enables 25 GbE SFP28 NICs in the integrated slot without consuming a PCIe expansion slot — critical for deployments that need 25 GbE without giving up Slot 1 and Slot 3
Storage Controllers — PERC 15G vs 14G — R450 introduces 15G PERC family (H345, H355, H745, H755) with PCIe Gen 4 interfaces; R440 used 14G PERC (H330, H730P, H740P, HBA330) on Gen 3; the R450's H755 Harpoon-based controller adds NV cache backed by flash rather than capacitor — improved cache persistence under power loss events
PSU Wattage — 1100 W Titanium vs 550 W Platinum — R450 supports PSU options from 600 W to 1100 W Titanium; the R440's maximum was 550 W Platinum; the R450's expanded PSU stack provides headroom for dual 165 W TDP processors, 16 DIMMs, 8 SAS drives, and dual 25 GbE NIC cards simultaneously under full load without approaching PSU capacity limits
Front VGA Added — R450 adds a VGA port on the front panel in addition to the existing rear VGA; the R440 had VGA only on the rear; front VGA enables local console access without sliding the server out or reaching to the rear panel — a service workflow improvement for dense rack environments
NVDIMM Removed — R440 supported NVDIMM persistent memory alongside DDR4 RDIMMs; R450 does not support NVDIMM; 3rd Gen Xeon Scalable's persistent memory strategy shifted to Optane PMem which is also not supported on R450 — workloads that required R440 NVDIMM capabilities should evaluate dedicated persistent memory platforms
