The HPE ProLiant DL320 Gen12 is designed to get more compute density out of each rack unit while reducing power and virtualization constraints. It delivers stronger expansion options than earlier generations, driven by Intel Xeon 6 processors that scale up to 144 cores, support for as much as 4 TB of memory, and PCIe Gen5 connectivity for higher performance and improved data-center efficiency.

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)
Front OCP SlotsP76982-B21 - Primary Front OCP Enablement Kit
P77261-B21 - Secondary Front OCP Enablement Kit
Rear OCP SlotsIncludes two standard rear OCP 3.0 slots (Slot 20 and Slot 21).
- 25 Gb or faster Ethernet adapter requires high performance fan selection
- If 1 or 2 Single Wide GPU is installed in front, it is advisable to install the GPUs in PCIe slots 4 and 6, with the Ethernet adapter installed in OCP slot A
- If 1 Double Wide GPU is installed in front, it is advisable to install the GPU in PCIe slots 5 and 6, with the Ethernet adapter installed in OCP slot B
- Silicon Root of Trust
- Firmware is signed with CNSA 2.0 approved algorithms
- Supports quantum-resistant (PQC) cryptography
- Continuous integrity checking and secure recovery
- Dedicated iLO network port (on the DC-SCM)
- iLO Service Port (USB) on the front for direct local access
- Remote console and virtual media
- RESTful API / Redfish support
- Integration with HPE Compute Ops Management and OneView
- Real-time server health monitoring
- Integrated Management Log (IML)
- Automatic detection of liquid cooling leaks (sends alerts and can force shutdown)
- Support for chassis intrusion detection
- iLO 7 runs on the Datacenter Secure Control Module (DC-SCM)
- Dedicated management processor separate from the main system board
