HPE DL380 Gen11 vs Lenovo SR650a V4
A specification-by-specification comparison of the HPE ProLiant DL380 Gen11 and the Lenovo ThinkSystem SR650a V4, built from HPE’s and Lenovo’s own documents. 1 headline measure favours the DL380 Gen11, 3 favour the SR650a V4, and they share no processors.
Bottom line. DL380 Gen11 leads on storage density. SR650a V4 leads on virtualisation, network throughput. Neither vendor publishes benchmarks for these machines, so every call here is made on what their documents state.
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 DL380 Gen11 if…
Drive bays: 36 against 8 on the SR650a V4
Five factory chassis — 8SFF, 24SFF, 8LFF, 12LFF and 12EDSFF — plus mid-tray and rear cages, so one model spans small SFF builds, 16 LFF bays and 36 EDSFF NVMe drives.
Choose the SR650a V4 if…
Cores, fully populated: 172 against 128 on the DL380 Gen11
Largest power supply: 3,200 W against 2,200 W on the DL380 Gen11
Fastest network option: 800 GbE class against 400 GbE class on the DL380 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
DL380 Gen11 vs SR650a V4, answered
Is the DL380 Gen11 or the SR650a V4 the faster server?
Neither document publishes benchmark results, so this page compares what they do state. The DL380 Gen11 lists 66 processors up to 64 cores at 385 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 DL380 Gen11 has 32 DIMM slots and a stated ceiling of 8.0 TB. The SR650a V4 has 32 and 8 TB.
Which takes more drives?
DL380 Gen11: 36 bays across 13 documented layouts. SR650a V4: 8 across 4. Counts include rear and mid-chassis positions where the vendor documents them.
Can either take GPUs?
DL380 Gen11: up to 8 accelerators, 3 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.
