Compact general-purpose server

The HPE ProLiant MicroServer Gen11 P86811-005 is an ultra micro tower system built around an Intel Xeon 6315P quad-core processor running at 2.80 GHz. It ships with 16 GB of HPE DDR5 standard memory on a single 4800 MT/s UDIMM and includes an embedded Intel VROC SATA controller. Four 1 GbE ports and two PCIe expansion slots provide baseline connectivity for small-office workloads.

Sustained-load behaviour

The 55 W processor and single standard fan are designed for continuous operation within the external 180 W slim power supply envelope. Memory runs at 4800 MT/s without overclocking, so bandwidth remains stable during extended file-serving or virtualisation tasks. The embedded SATA controller handles steady I/O to non-hot-plug drives without a dedicated RAID battery.

Pre-order checks

Verify that your rack or shelf accommodates an ultra micro tower form factor and that the 180 W external power supply can reach a suitable outlet. Confirm the two PCIe slots match the add-in cards you plan to install and that the four 1 GbE ports satisfy your network topology. Ensure the single 16 GB UDIMM leaves room for future memory expansion within the platform limits.

Questions about this item

How much power does the Xeon 6315P 2.8GHz 4-core CPU draw under sustained load?

The processor is rated at 55W, so continuous operation will stay within that thermal envelope.

Which drives and memory modules must I supply to use the four 3.5-inch bays and the single DDR5 slot?

The system accepts SATA drives in its four non-hot-plug bays and uses one 16GB DDR5 UDIMM at 4800 MT/s.

Will my existing PCIe 3.0 add-in cards work in the two expansion slots?

Yes, the two PCIe slots are backward compatible with PCIe 3.0 cards.
