Head-to-head · every figure from the vendor documents

Dell R740 vs HPE DL380a Gen11

A specification-by-specification comparison of the Dell PowerEdge R740 and the HPE ProLiant DL380a Gen11, built from Dell’s and HPE’s own documents. 2 headline measures favour the R740, 3 favour the DL380a Gen11, and they share no processors.

Bottom line. R740 leads on storage density. DL380a Gen11 leads on virtualisation, AI and acceleration, network throughput. Neither vendor publishes benchmarks for these machines, so every call here is made on what their documents state.

Dell PowerEdge R740 rear: three PCIe risers carrying slots 1 to 8, the iDRAC, serial, VGA and USB ports, four rNDC ports and two 1100 W supplies

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 R740 if…

  • Drive bays: 16 against 8 on the DL380a Gen11
  • Largest power supply: 2,600 W against 2,200 W on the DL380a Gen11
  • Keeping every drive at the front is the trade that buys room inside: Dell allows this model three double-width 300 W accelerators or six single-width 150 W ones, plus three double-width or four single-width FPGAs, with no drive-chassis condition attached. The R740xd’s equivalent row stops at two cards and ties them to its 24-bay build.

Choose the DL380a Gen11 if…

  • Cores, fully populated: 128 against 56 on the R740
  • Accelerators: Up to 8 against Up to 6 on the R740
  • Fastest network option: 400 GbE class against 25 GbE class on the R740
  • 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.

07 — Questions

R740 vs DL380a Gen11, answered

Is the R740 or the DL380a Gen11 the faster server?

Neither document publishes benchmark results, so this page compares what they do state. The R740 lists 111 processors up to 28 cores at 205 W; the DL380a Gen11 lists 41 up to 64 cores at 350 W. Fully populated that is 56 cores against 128.

Which holds more memory?

The R740 has 24 DIMM slots and a stated ceiling of 3 TB with RDIMM/LRDIMM. The DL380a Gen11 has 24 and 3.0 TB.

Which takes more drives?

R740: 16 bays across 3 documented layouts. DL380a Gen11: 8 across 2. Counts include rear and mid-chassis positions where the vendor documents them.

Can either take GPUs?

R740: up to 6 accelerators, 2 double-wide cards listed. DL380a Gen11: up to 8, 0 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. R740: Dell EMC PowerEdge R740 and R740xd Technical Guide (Rev. A12, August 2022) (Dell document). DL380a Gen11: HPE ProLiant DL380a Gen11 QuickSpecs (Version 34 - August 3, 2026) (HPE document). Each claim on this page is derived from those documents, checked page by page on the two data sheets, and carries no pricing.
