HPE DL380a Gen11 vs Lenovo SR650a V4

A specification-by-specification comparison of the HPE ProLiant DL380a Gen11 and the Lenovo ThinkSystem SR650a V4, built from HPE’s and Lenovo’s own documents. None of the headline measures favour the DL380a Gen11; 4 favour the SR650a V4, and they share no processors.

Bottom line. SR650a V4 leads on virtualisation, databases and in-memory work, network throughput. Neither vendor publishes benchmarks for these machines, so every call here is made on what their documents state.

The measures that decide it

Each row is a figure both vendors publish. Bars show the split between the two; a badge marks the larger figure, which is not always the better buy — a shallower chassis or a lower power ceiling can matter more.

02 — Verdict

Which one, and why

Drawn from the measures above and each model’s own data sheet. Neither vendor publishes benchmark results for these servers, so nothing here claims one is “faster”.

Choose the DL380a Gen11 if…

  • Four double-wide or eight single-wide accelerators in a 2U chassis, with six NVIDIA and Intel cards in HPE’s GPU table spanning the 72 W L4 to the 400 W H100 NVL.

Choose the SR650a V4 if…

  • Cores, fully populated: 172 against 128 on the DL380a Gen11
  • Memory ceiling: 8 TB against 3 TB on the DL380a Gen11
  • Largest power supply: 3,200 W against 2,200 W on the DL380a Gen11
  • One 2U chassis spans eight low-profile L4 cards, four double-wide cards of up to 450 W, or a pair of 600 W H200 NVL or RTX PRO 6000 Blackwell GPUs, all in PCIe 5.0 front slots.

07 — Questions

DL380a Gen11 vs SR650a V4, answered

Is the DL380a Gen11 or the SR650a V4 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The DL380a Gen11 lists 41 processors up to 64 cores at 350 W; the SR650a V4 lists 27 up to 86 cores at 350 W. Fully populated that is 128 cores against 172.

Which holds more memory?

The DL380a Gen11 has 24 DIMM slots and a stated ceiling of 3.0 TB. The SR650a V4 has 32 and 8 TB.

Which takes more drives?

DL380a Gen11: 8 bays across 2 documented layouts. SR650a V4: 8 across 4. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

DL380a Gen11: up to 8 accelerators, 0 double-wide cards listed. SR650a V4: up to 8, 4 double-wide listed.

Do they share any processors?

No. The two documents list different processors, so a like-for-like processor build is not possible across these two.

Where these figures come from. DL380a Gen11: HPE ProLiant DL380a Gen11 QuickSpecs (Version 34 - August 3, 2026) (HPE document). SR650a V4: Lenovo ThinkSystem SR650a V4 and SR650i V4 Servers (August 27, 2026) (Lenovo document). Each claim on this page is derived from those documents, checked page by page on the two data sheets, and carries no pricing.
