HPE Microsvr G11 6315P 1X16G NHP NA SVR - P86811-005

HPE P86811-005 ProLiant MicroServer Gen11 Ultra Micro Tower Server

Overview

The HPE ProLiant MicroServer Gen11 P86811-005 is a compact, ultra micro tower server built for small offices, remote sites, and edge deployments where rack space is a luxury but enterprise-grade reliability is still a requirement. Powered by an Intel Xeon 6315P processor at 2.80 GHz with four cores and backed by 16GB of DDR5 memory, this unit delivers enough headroom for general-purpose server workloads — file sharing, lightweight virtualization, local NVR duties, or branch-office compute — without the footprint or power draw of a full rack system. If you're evaluating the HPE ProLiant line for a space-constrained environment, the P86811-005 (often searched as P86811 005) belongs on your shortlist.

Key Features

• Intel Xeon 6315P @ 2.80 GHz, Quad-Core, 12MB L3 Cache: The Xeon 6 architecture brings server-class error handling and platform stability that consumer processors don't — relevant when this box is running 24/7 unattended at a remote site. Four cores at 2.80 GHz handle concurrent workloads like simultaneous video recording plus management-plane tasks without bottlenecking either.
• 16GB DDR5 UDIMM at 4800 MT/s: DDR5 at 4800 MT/s delivers roughly 50% more memory bandwidth than DDR4-3200 — meaningful when streaming multiple high-resolution video feeds or running in-memory databases. The single 16GB UDIMM leaves memory slots open for future expansion without replacing the installed module.
• 4 Large Form Factor Non-Hot-Plug Bays: Four LFF drive bays give you room for high-capacity HDDs — think 4x 8TB or 4x 16TB configurations for on-premises storage-heavy workloads like video retention or local backup. Non-hot-plug means drive swaps require a planned maintenance window, so factor that into your availability requirements.
• Embedded Intel VROC SATA for HPE ProLiant Gen11: The onboard SATA controller handles local storage without consuming a PCIe slot, and VROC support means you can configure RAID for data protection directly in firmware — no add-in card required for basic redundancy.
• Embedded 4-Port 1GbE Ethernet: Four onboard Gigabit ports give you enough interface density to segment traffic — management, data, iSCSI storage, and a spare — without adding a NIC. For network switch planning, each port draws standard 1GbE; no 10GbE here unless you add a PCIe NIC.
• 2 PCIe Expansion Slots: Two PCIe slots let you extend the platform — add a 10GbE NIC, an HBA for direct-attached storage expansion, or a GPU for lightweight inference workloads. For surveillance use cases, this is where you'd drop a capture or analytics accelerator card.
• 180W Slim External Power Supply: The 180W external power brick keeps the chassis small and fanless (from the PSU side), but it also means power delivery is capped — plan your drive and PCIe card TDPs accordingly. The Xeon 6315P itself is rated at 55W, leaving roughly 125W for drives and expansion.
• iLO Management Kit Included: HPE iLO (Integrated Lights-Out) enables out-of-band remote management — power cycling, BIOS access, hardware health monitoring, and remote console — without needing physical access to the unit. Critical for remote or unmanned deployments where sending a technician on-site is expensive.

Integration and Compatibility

The P86811-005 fits naturally into environments already running HPE infrastructure, where iLO integrates with HPE OneView or Agentless Management for centralized monitoring. The four embedded 1GbE ports support standard LACP bonding for increased throughput or active-passive failover. For network video recorder deployments, the four LFF bays combined with the embedded SATA controller support common NVR software stacks that manage local storage directly. PCIe slot availability means the platform can be extended with capture cards or GPU-based analytics engines as workloads grow. DDR5 memory uses a different socket than DDR4, so any future memory upgrades must be HPE-qualified DDR5 UDIMMs compatible with the Gen11 platform — mixing is not supported.

Frequently Asked Questions

Q: What processor does the P86811-005 use, and what is its TDP?

A: The P86811-005 ships with an Intel Xeon 6315P running at 2.80 GHz with four cores, 12MB L3 cache, and a 55W TDP. This is a server-class processor with ECC memory support.

Q: How many drives can the MicroServer Gen11 P86811-005 support?

A: The unit provides four Large Form Factor (LFF) non-hot-plug bays. These accommodate standard 3.5-inch HDDs or 2.5-inch drives with an adapter. Drive swaps require powering down the unit — there is no hot-swap capability on this model.

Q: Can the P86811-005 be used as a network video recorder (NVR) for IP camera systems?

A: Yes. The combination of four LFF storage bays for high-capacity HDDs, embedded 4-port 1GbE networking, and PCIe expansion for capture or analytics cards makes it a viable on-premises NVR platform. Confirm your chosen NVR software is compatible with Windows Server or Linux on HPE Gen11 hardware before deploying.

Q: What is the memory configuration, and can it be expanded?

A: The server ships with 1x 16GB HPE DDR5 UDIMM at 4800 MT/s. Additional memory can be installed in the remaining DIMM slots using HPE-qualified DDR5 UDIMMs compatible with the Gen11 platform.

Q: Does the P86811-005 include remote management capability?

A: Yes. The listing indicates an iLO Kit is included, which enables HPE Integrated Lights-Out remote management — covering power control, health monitoring, remote console, and BIOS access without physical presence at the unit.

Q: What are the power requirements for the P86811-005?

A: The unit ships with a 180W slim external power supply. The Xeon 6315P CPU is rated at 55W, leaving headroom for drives and PCIe add-in cards, but the 180W ceiling should be factored into configurations with multiple high-capacity HDDs and expansion cards.

The P86811-005 is a server I'd recommend specifically for integrators who need a convincing edge-compute story without the conversation about rack space or three-phase power. The 55W Xeon 6315P keeps heat output manageable in a closet or under-desk deployment, and the four LFF bays give you real storage capacity — not the token M.2-only configurations you see on some small-form-factor competitors.

Technical Highlights:

• DDR5 at 4800 MT/s: Substantially higher memory bandwidth than the DDR4 platforms this generation replaces — worth noting when the workload involves concurrent high-bitrate video ingest and database queries against the same memory bus.
• 4-Port Embedded 1GbE: Four discrete Gigabit interfaces on a system this size is unusual. You can assign dedicated ports for management (iLO), data, storage fabric, and a spare without touching either PCIe slot.
• Xeon 6315P 12MB L3 Cache: Larger L3 cache than comparable desktop or workstation processors at this core count — reduces memory round-trips on latency-sensitive workloads like real-time video analytics or authentication lookups.

Deployment Considerations:

• The 180W external power supply is the platform's hard ceiling — budget your drive TDPs carefully if you fill all four bays with high-RPM or high-capacity HDDs alongside a PCIe add-in card. A four-drive configuration with a NIC could push close to that limit under sustained load.
• Non-hot-plug storage means any drive failure on a solo unit requires a maintenance window and physical access — plan your RAID level and spare strategy before commissioning, especially on unmanned remote sites.

This unit is well-suited for a branch-office or remote-site NVR anchor — small enough to fit on a shelf, capable enough to run a 16–24 camera NVR workload locally, and manageable remotely via iLO without dispatching a technician every time a reboot or BIOS change is needed.
