HPE DL360 Gen9 vs Gen10: The 1U Workhorse Compared

The DL360 Gen9 and DL360 Gen10 fill the same role: a 1U, two-socket ProLiant bought in quantity and racked in rows. From the cold aisle they are hard to tell apart. What separates them is the socket, the memory controller, the backplane options and the management silicon, and those four things decide which one belongs in your rack.

Two platforms under a similar lid

Gen9 is built around Intel Xeon E5-2600 v3 (Haswell-EP) and v4 (Broadwell-EP) processors in socket LGA 2011-3. That gives up to 22 cores per socket with the largest v4 parts, four memory channels per CPU, PCIe 3.0 throughout, and a supported processor ceiling of 145 W.

Gen10 moves to first- and second-generation Xeon Scalable processors in Socket P (LGA 3647): up to 28 cores per socket, six memory channels per CPU, still PCIe 3.0, and support for processors up to 205 W when the server is configured with the high-performance heatsink and fan kit. AVX-512 arrives with Scalable as well, which matters for encoding, HPC and some analytics work and does nothing at all for a typical hypervisor or file node.

Almost nothing crosses over between them. Processors, heatsinks, system boards, drive carriers and the qualified DIMM lists are all generation specific. HPE's Flexible Slot power supply family spans both generations, so common Flex Slot units often carry forward, but check the individual part against the QuickSpecs for the generation you are building.

Memory is where the generations separate

Both servers carry 24 DIMM slots, but they get there differently. Gen9 uses four channels per CPU with three DIMMs per channel; Gen10 uses six channels per CPU with two DIMMs per channel. Six channels against four is roughly fifty percent more theoretical bandwidth per socket before clock speed enters the picture, and clock speed favors Gen10 too.

The third DIMM per channel on Gen9 carries a penalty: populating it drops the memory clock, so a fully loaded Gen9 does not run at its headline speed. Gen10 is not immune, since 2933 generally requires one DIMM per channel, but the drop is smaller and the starting point higher. Gen10 also accepts Intel Optane persistent memory alongside second-generation Scalable processors, which is occasionally the entire reason a team specifies one. If your workload is memory-bandwidth bound, that gap is the argument. If it is bound by the network, the array or software licensing, it barely shows up.

Storage and expansion inside 1U

Both generations ship in 4LFF, 8SFF and 10SFF chassis, and both offer up to three PCIe 3.0 slots through a two-slot primary riser and a single-slot secondary riser, with the secondary riser dependent on the second processor being installed. Networking sits on a FlexibleLOM connector on both, so a 10GbE adapter does not consume one of those slots.

NVMe is the split. On Gen9 it arrived as an add-on, with express bay kits converting a small number of front bays while the rest stayed SAS or SATA. Gen10 has backplane options designed around it, up to ten NVMe bays in the right build. If the plan is an all-flash 1U node on PCIe-attached drives, that decision is made for you.

Controllers follow the generation: the Smart Array P440ar in a dedicated slot on Gen9, the modular E208i-a and P408i-a on Gen10, with S100i software RAID on the board for light duty. For software-defined storage, specify the HBA-mode controller rather than a RAID card presenting single-disk volumes.

Management and support runway

Gen9 runs iLO 4 and Gen10 runs iLO 5. Day to day they feel similar: remote console, virtual media, inventory, Redfish, syslog and SNMP, with console and virtual media behind the Advanced license tier on both. iLO 5 adds the silicon root of trust and firmware validation and recovery features that some security reviews now ask about by name.

Two practical points outweigh the feature lists. HPE requires an active warranty or support agreement to download Service Pack for ProLiant and most component firmware, so decide how you will patch before the server lands, whichever generation you buy. And hypervisor and OS vendors trim older processor generations from their compatibility lists with each major release; Gen9's Haswell and Broadwell cores sit closer to that line than Gen10's Scalable parts. Check the HCL for the exact release you intend to run.

Which one belongs in your rack

A Gen9 makes sense for lab and dev/test capacity, edge and branch sites, disaster recovery targets, backup proxies, and general virtualization hosts limited by the network or the array rather than the CPU. It fits especially well into estates that are already Gen9, where spare risers, caddies, rails and power supplies are on the shelf.

A Gen10 earns its place when the workload wants memory bandwidth, when NVMe front bays are part of the design, when per-socket licensing rewards higher core counts on fewer sockets, or when firmware integrity features are a requirement rather than a preference.

Where to go from here

Browse the DL360 Gen9 inventory if you are matching an existing fleet or filling out lab and edge capacity, and the DL360 Gen10 inventory if bandwidth, NVMe or support lifetime drives the decision.
