HPE DL380a Gen12 vs Lenovo SR860 V4

A specification-by-specification comparison of the HPE ProLiant Compute DL380a Gen12 and the Lenovo ThinkSystem SR860 V4, built from HPE’s and Lenovo’s own documents. 1 headline measure favours the DL380a Gen12, 4 favour the SR860 V4, and 7 processors appear in both lists.

Bottom line. DL380a Gen12 leads on AI and acceleration. SR860 V4 leads on virtualisation, databases and in-memory work, storage density. 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 Gen12 if…

  • Accelerators: Up to 10 against Up to 8 on the SR860 V4
  • Ten double-wide GPU positions in 4U, with the H200 NVL, RTX PRO 6000 Blackwell, RTX PRO 6000D, L40S, L20 and L4 in HPE’s accelerator list.

Choose the SR860 V4 if…

  • Processor sockets: 4 against 2 on the DL380a Gen12
  • Cores, fully populated: 344 against 288 on the DL380a Gen12
  • Memory ceiling: 16 TB against 8 TB on the DL380a Gen12
  • Fifty-six front drives in one chassis: 32 E3.S 1T NVMe bays over 24 × 2.5-inch SAS/SATA bays, or 48 × 2.5-inch with up to 24 of them NVMe.

07 — Questions

DL380a Gen12 vs SR860 V4, answered

Is the DL380a Gen12 or the SR860 V4 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The DL380a Gen12 lists 32 processors up to 144 cores at 350 W; the SR860 V4 lists 7 up to 86 cores at 350 W. Fully populated that is 288 cores against 344.

Which holds more memory?

The DL380a Gen12 has 32 DIMM slots and a stated ceiling of 8.0 TB. The SR860 V4 has 64 and 16 TB.

Which takes more drives?

DL380a Gen12: 16 bays across 2 documented layouts. SR860 V4: 56 across 4. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

DL380a Gen12: up to 10 accelerators, 0 double-wide cards listed. SR860 V4: up to 8, 1 double-wide listed.

Do they share any processors?

Yes — 7 processors appear in both documents, including the Intel Xeon 6788P. That makes a like-for-like build possible on either server.

Where these figures come from. DL380a Gen12: HPE ProLiant Compute DL380a Gen12 QuickSpecs (Version 20 - 08-Sep-2026) (HPE document). SR860 V4: Lenovo ThinkSystem SR860 V4 Server (September 7, 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.
