HPE DL560 Gen11 vs Lenovo SR850 V4
A specification-by-specification comparison of the HPE ProLiant DL560 Gen11 and the Lenovo ThinkSystem SR850 V4, built from HPE’s and Lenovo’s own documents. None of the headline measures favour the DL560 Gen11; 5 favour the SR850 V4, and they share no processors.
Bottom line. SR850 V4 leads on virtualisation, storage density, AI and acceleration, 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.
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 DL560 Gen11 if…
- 240 cores from four 60-core Platinum 8490H processors, with sixteen DIMM slots per socket, in a 2U chassis.
Choose the SR850 V4 if…
- Cores, fully populated: 344 against 240 on the DL560 Gen11
- Drive bays: 32 against 24 on the DL560 Gen11
- Accelerators: Up to 4 against Up to 2 on the DL560 Gen11
- Four sockets and 64 DIMM slots in 2U: filled with 256 GB 3DS RDIMMs the server reaches 16 TB, the same ceiling Lenovo quotes for the 4U SR860 V4.

DL560 Gen11 vs SR850 V4, answered
Is the DL560 Gen11 or the SR850 V4 the faster server?
Neither document publishes benchmark results, so this page compares what they do state. The DL560 Gen11 lists 9 processors up to 60 cores at 350 W; the SR850 V4 lists 7 up to 86 cores at 350 W. Fully populated that is 240 cores against 344.
Which holds more memory?
The DL560 Gen11 has 64 DIMM slots and a stated ceiling of 16.0 TB. The SR850 V4 has 64 and 16 TB.
Which takes more drives?
DL560 Gen11: 24 bays across 4 documented layouts. SR850 V4: 32 across 4. Counts include rear and mid-chassis positions where the vendor documents them.
Can either take GPUs?
DL560 Gen11: up to 2 accelerators, 1 double-wide cards listed. SR850 V4: up to 4, 1 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. DL560 Gen11: HPE ProLiant DL560 Gen11 QuickSpecs (Version 33 - 03-Aug-2026) (HPE document). SR850 V4: Lenovo ThinkSystem SR850 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.
