HPE ProLiant DL365 Gen11 Server Specifications and Compatible Hardware

The HPE ProLiant DL365 Gen11 is a 1U, two-socket rack server built around 4th Generation AMD EPYC processors and DDR5 registered memory. Its factory configurations include an 8SFF chassis, an EDSFF NVMe chassis and a GPU-oriented chassis. This guide summarizes supported hardware, the configuration rules that govern upgrades, and links to detailed component reference pages.

The QuickSpecs identifies compute-intensive workloads such as VDI, electronic design automation (EDA) and computer-aided design (CAD). This reference follows the attached HPE QuickSpecs, including its model-specific restrictions and discrepancies.

DL365 Gen11 specifications at a glance

The values below describe the platform; some maximums depend on the exact chassis and processor/cooling configuration.

Server chassis and front storage configurations

The three CTO chassis families are not interchangeable product descriptions. The 8SFF CTO starts with an 8SFF cage but does not include its backplane. The EDSFF and GPU CTO configurations have separate mandatory processor, thermal and backplane choices. The GPU CTO entry on page 18 lists a 20 EDSFF included cage, while the GPU-specific backplane options on page 22 require a 4SFF NVMe or 8EDSFF front backplane; this discrepancy needs verification for exact orders.

8SFF front-bay layouts and backplanes

The optional media position can house a 2SFF U.3 cage for a maximum of 10 front SFF drives or an optical drive. HPE lists x1 and x4 8SFF U.3 backplanes, a 2SFF x4 backplane, and an NVMe trigger kit. The required storage cables and controller/direct-attach path depend on the chosen backplane. A maximum drive count does not mean every CPU/cooling combination supports that maximum.

Processors and DDR5 memory

The two-socket platform lists 4th Generation AMD EPYC processor kits including standard, F-series, Bergamo and X-series options. A second CPU must match the first processor model, and processor kits do not automatically include heatsinks and fans. While the front overview mentions 96 cores, the option-kit list includes 112-core EPYC 9734 and 128-core EPYC 9754 parts. Check the selected CPU kit and thermal configuration rather than relying on the introductory core count.

The platform has 12 memory channels per processor and 24 DIMM sockets only when two processors are installed. Registered DDR5-4800 DIMMs include 16GB through 256GB choices. HPE prohibits mixing x4 and x8 DIMMs and mixing 3DS with non-3DS modules. The 128GB/256GB options require performance heatsinks and seven performance fans; 256GB memory may have additional constraints.

Storage technologies and capacity planning

HPE lists SAS and SATA hard drives, SAS and SATA SSDs, NVMe Gen4 U.3 SFF SSDs, and NVMe Gen5 E3.S EDSFF SSDs. The standard-feature maximum-storage examples are based on 8+2 SFF configurations, not universal capacity guarantees. In addition to media type and capacity, the backplane, controller, cables, CPU wattage and cooling configuration govern usable drive combinations.

The source does not present an equivalent consolidated EDSFF capacity table. On the 8SFF CTO without direct liquid cooling, processors at or above 320W limit the configuration to eight drives. On the EDSFF CTO, the same CPU wattage threshold limits EDSFF drive count to 12, unless a DLC module is selected. For GPU CTO, the 4SFF or 8EDSFF GPU backplanes specified on page 22 are motherboard-attached and do not allow internal controllers.

The optional NS204i-u provides externally accessible hot-plug mirrored boot media with two embedded 480GB NVMe SSDs, and requires the documented low-profile secondary riser arrangement.

Networking, OCP and PCIe expansion

The chassis does not include a standard Ethernet data port in its CTO baseline. It offers network adapter selection through PCIe cards and OCP 3.0, while the dedicated 1Gb HPE iLO management port remains separate. The QuickSpecs lists Ethernet, Fibre Channel and HDR/NDR InfiniBand choices; adapter thermal rules and OCP upgrade cabling must be checked per configuration.

PCIe Gen5 x16 expansion is available through a standard primary riser and an optional second riser. Secondary riser forms cannot occupy the same physical position simultaneously. GPU CTO adds front GPU riser positions and GPU-specific bandwidth/space limitations.

Power, fans and thermal configurations

Flex Slot power-supply selections include 800W Platinum, 1000W Titanium, 1600W Platinum, 1800W-2200W Titanium, and 1600W -48VDC. Power supply SKUs cannot be mixed in a two-PSU configuration. The 1800W-2200W selection requires 200-240VAC high-line power, while the -48VDC PSU requires its documented lug or cable accessory. HPE recommends sizing with Power Advisor.

Cooling selections are configuration-dependent. The QuickSpecs requires performance cooling for processor, NVMe, EDSFF, GPU and high-density configurations. Performance heatsinks or DLC may be needed for high-power CPUs, and DLC includes additional module and tube-kit requirements. Detailed thresholds are described in the processor and cooling guides.

Important configuration checks before ordering

These are source-specific restrictions, not general assumptions about every HPE Gen11 server. Factory CTO eligibility and field upgrades can differ, and HPE recommends verifying final combinations in an approved configurator.
