HPE P87788-005 ProLiant ML350 Gen12 Tower Server
The HPE ProLiant ML350 Gen12 — ordered as P87788-005 — is a mid-range enterprise tower server built around AMD's EPYC 6515P 16-core processor. At 88 lb and 39.50 × 24.00 × 13.20 inches, this is a full-depth tower platform engineered for on-premises workloads where rack space is limited but compute density still matters. It ships configured with 1×64GB DDR5 RDIMM, 8 small form-factor drive bays, an HPE MR408i-O storage controller, and 2×480GB SATA SSDs — a ready-to-expand baseline for storage-intensive applications like network video recording, database hosting, or edge compute.
Key Features
- AMD EPYC 6515P 16-Core Processor: A single-socket EPYC 9004-series die delivers high per-core throughput with broad PCIe 5.0 lane availability — meaning you can add GPU accelerators or high-bandwidth NIC cards without PCIe bottlenecking becoming a constraint, which matters for analytics-heavy workloads running alongside recording or database engines.
- 1×64GB DDR5 RDIMM (1P baseline): Ships with one 64GB registered DIMM across a multi-channel DDR5 memory subsystem. The ML350 Gen12 platform supports additional DIMM population — so this unit is a starting point, not a ceiling, for memory-intensive applications requiring in-memory data processing.
- 8 Small Form Factor Drive Bays: Eight SFF bays support SAS/SATA/NVMe drives (verify backplane variant before ordering NVMe). Combined with the MR408i-O controller, you have a direct path to hardware RAID for data protection without adding an external controller card — relevant for any 24/7 recording or transactional database environment where drive failure tolerance is non-negotiable.
- HPE MR408i-O Storage Controller: An onboard RAID controller with its own cache and battery-backup capability (verify cache/battery options for this specific configuration) — separating storage logic from the host CPU so RAID rebuild events don't degrade compute throughput during active workloads.
- 2×480GB SATA SSD (Base Storage): Factory-installed SSDs provide OS and application storage out of the box. For surveillance NVR deployments or data-intensive workflows, the remaining SFF bays can be populated post-delivery with high-capacity spinning media or additional SSDs. Refer to HPE server compatible drive lists before specifying media.
- Tower Form Factor — 88 lb, Full Depth: At 39.50 inches deep and 88 lb, this platform requires a stable surface and adequate floor/shelf load rating. It is NOT a rack unit — plan accordingly if your environment is a standard 19-inch equipment rack. If rack mounting is required, HPE offers a tower-to-rack conversion kit for the ML350 line.
Integration and Compatibility
The ML350 Gen12 is supported under HPE's ProLiant management ecosystem including iLO (Integrated Lights-Out) for remote server management — relevant for IT teams managing servers in remote or unstaffed locations. For video surveillance infrastructure, pair this platform with a Windows Server OS and a compatible VMS such as Milestone XProtect, Genetec Security Center, or Exacq — verify VMS vendor hardware compatibility lists for Gen12 EPYC platform support before commissioning. For network integration, budget for a 10GbE or 25GbE NIC if the workload requires high-bandwidth storage or camera-feed ingestion beyond the built-in 1GbE ports.
Frequently Asked Questions
Q: What processor does the P87788-005 ship with?
A: The P87788-005 is configured with a single AMD EPYC 6515P 16-core processor — a 1P (single-processor socket) configuration based on the SKU descriptor.
Q: How much memory does the P87788-005 include, and can it be expanded?
A: It ships with 1×64GB DDR5 RDIMM. The ML350 Gen12 platform supports additional DIMM population; consult HPE's memory configurator or a pre-sales specialist for validated expansion options before ordering additional DIMMs.
Q: Is this a rack server or tower server?
A: The ML350 Gen12 is a tower server. At 39.50 inches deep and 88 lb, it requires floor or shelf placement. An optional HPE tower-to-rack conversion kit exists for the ML350 line if rack mounting is needed.
Q: What storage controller is included, and what RAID levels does it support?
A: The P87788-005 includes the HPE MR408i-O controller. Supported RAID levels depend on controller firmware and any installed cache/battery options — verify with HPE's QuickSpecs document for this configuration.
Q: Can additional drives be added to the P87788-005?
A: Yes. The server ships with 8 SFF drive bays and 2×480GB SSDs installed, leaving 6 bays available for expansion. Backplane type (SAS/SATA vs. NVMe) determines compatible drive options — confirm the backplane variant before specifying NVMe media.
The P87788-005 is a configuration I'd recommend for organizations running on-premises VMS or database workloads where rack space isn't available but per-core compute performance matters. The EPYC 6515P's 16-core count at a single socket is a meaningful specification here — it means you're not paying for a second-socket platform you don't need, while still getting PCIe 5.0 lane density that supports add-in accelerators or 25GbE NICs without bandwidth starvation.
Technical Highlights:
- 8 SFF Drive Bay Capacity: Six bays open for expansion beyond the factory 2×480GB SSDs — at current high-capacity SAS pricing, you can build meaningful raw storage tiers without touching external JBODs for moderate channel counts.
- 88 lb Tower Footprint (39.50 × 24.00 × 13.20 in): This is a substantial physical platform. Floor load rating and physical access clearance at 39.50 inches depth are real installation variables — measure your deployment space before delivery, not after.
- MR408i-O Onboard RAID Controller: Offloads RAID processing from the EPYC host CPUs, which keeps compute headroom available for application threads during rebuild events — a material concern on 24/7 recording platforms where a drive failure mid-shift cannot be allowed to degrade stream ingestion.
Deployment Considerations:
- Single-socket configuration means memory bandwidth is limited to one EPYC memory domain — if your workload is heavily memory-bandwidth-bound (e.g., high-channel-count analytics), benchmark with your VMS vendor before committing to 1P vs. considering a 2P alternative in the ML350 line.
- Tower form factor requires physical access for drive swaps; confirm hot-swap backplane support for this specific bay configuration if you expect to replace drives during production hours without a service window.
For a medium-density physical security operations center or a distributed enterprise branch server room where rack infrastructure doesn't exist, the P87788-005 is a deployable, expandable compute platform — specifically suited to environments running 20–60 camera channels on a single VMS instance with local storage retention.
