The MR (MegaRAID) and SR (SmartRAID) controller families use different management tools and cannot be installed together in the same server. When paired with a tri-mode U.3 backplane, both series support SAS, SATA, and NVMe drives, allowing mixed drive types in one system. This server has no built-in software RAID. Direct-attached SATA drives run in AHCI mode only, so a hardware RAID controller is required for any RAID functionality.
SR Series (SmartRAID)
SR Series
Installation Service Manual
The SR series is the high-end controller line, only available in type-p PCIe form factor.
This is the go-to choice for high drive count configurations or maximum storage throughput. Like the cached MR controllers it requires a battery or capacitor for cache protection.
MR Series (MegaRAID) - View PDF
MR Series
Installation Service Manual
The MR series is the broader, more flexible controller line available in both type-o and type-p form factors.
The cached models (MR408i-o, MR416i-o, MR416i-p) add a Flash-Backed Write Cache (FBWC)
Choosing Between MR and SR
- All HPE MRxxx RAID controllers support SAS, SATA, and NVMe drives
- Need OCP slot deployment → MR type-o only
- Simple RAID, no cache needed → MR216i-o or MR216i-p
- Need cache, moderate drive count → MR408i-o or MR416i-o/p
- Maximum drive count or throughput → MR932i-p
- External SAS/SATA storage → E208e-p (Gen10, type-p, external only)
Every DL345 Gen12 starts with rear OCP 3.0 Slot A (x16). Use the kits below for Slot B bandwidth or front OCP on SFF/EDSFF and GPU CTO servers:
- P81908-B21 — OCP Slot B x8 Enablement: enables rear OCP Slot B (select one or two kits depending on required Slot B bandwidth).
- P77277-B21 — Front Primary OCP: Front GPU / Primary Front OCP enablement path for SFF/EDSFF and GPU CTO (QuickSpecs).
- P81903-B21 — Front Secondary OCP: select only after Front Primary; SFF/EDSFF and GPU CTO only.
- Shared NIC / Wake-on-LAN: rear OCP A/B and front Primary support shared-NIC and WOL; front Secondary supports WOL only. Keep at least one supported OCP Ethernet if shared-NIC/WOL through iLO is required.

Front Primary OCPP77277-B21
Front Secondary OCPP81903-B21
- Slot 6 PCIe 5.0 x16 is default on CTO servers; primary/secondary riser cages add Slots 1–5.
- P81904-B21 Slot 3 riser kit — select first when expanding primary riser.
- P81905-B21 Slot 1/2 riser kit — select after Slot 3 riser (P81904-B21).
- P81906-B21 Slot 4/5 riser kit — secondary riser cage.
- GPU CTO P81949-B21 adds front PCIe Slots 10/12 (default) and optional 15/17 for front GPUs.
- OCP B bandwidth depends on how many P81908-B21 enablement kits are selected (QuickSpecs Expansion Options).
Slot 3 RiserP81904-B21
Slot 1/2 RiserP81905-B21
Slot 4/5 RiserP81906-B21
- Up to 6 single-width or 4 double-width GPUs (card and thermal limits apply).
- 8LFF / SFF·EDSFF CTO: rear PCIe GPU installs; follow QS thermal table for fan / heatsink / ambient.
- GPU CTO P81949-B21: front GPU cage; use Front 4xGPU Enablement Kit P84160-B21 for four-GPU front layouts.
- High-power front GPUs (e.g. L40S / RTX PRO 4500) need the matching GPU power cable kits (QuickSpecs Graphics Options).
- High-TDP CPU + multi-GPU configs may require Direct Liquid Cooling — see QS GPU / DLC notes.
