Expert Analysis

AI-assisted analysis based on published specifications

These three 1U single-socket servers share a common foundation — one Intel Xeon 6300, Xeon E-2400 or Pentium processor and four DDR5 UDIMM slots holding up to 128 GB, running at up to 4400 MT/s — but diverge in their design priorities. The Dell PowerEdge R260 and HPE ProLiant DL20 Gen11 both accept the 12-core Xeon 6377P, while the Lenovo ThinkSystem SR250 V3 stops at 8 cores. Depth varies too: the DL20 Gen11 is the most compact at 37.84 cm (SFF) or 38.22 cm (LFF), the R260 is 461.14 mm deep without its bezel (426.6 mm with the cabled PSU), and the SR250 V3 is 561 mm deep.

The HPE DL20 Gen11 has the most networking out of the box, with a four-port 1GbE embedded NIC, an OCP 3.0 slot and a PCIe 5.0 x16 slot, and the widest power choice: a 290 W non-redundant supply, or 500 W, 800 W and 1000 W Flex Slot units that can be paired for 1+1 redundancy. Its storage tops out at six SFF bays with the 2SFF kit (up to two NVMe U.3 drives) or two LFF bays. The Lenovo SR250 V3 has the most drive bays — eight 2.5-inch or four 3.5-inch, up to 96 TB — plus two M.2 SATA drives on an adapter in a PCIe slot, but it has no OCP slot: two 1GbE ports are onboard and faster networking needs a PCIe adapter (the riser provides either two Gen4 x8 slots or one Gen5 x16 slot). It takes one or two 800 W hot-swap supplies, redundant when two are fitted; Lenovo has withdrawn the 300 W fixed supply. The Dell R260 has two 1GbE LOM ports, two PCIe Gen4 slots, up to six 2.5-inch or two 3.5-inch drives, and a non-redundant 450 W or 700 W supply.

The choice therefore turns on priorities. The DL20 Gen11 suits shallow racks and sites that want redundant power, four onboard 1GbE ports and an OCP slot; the SR250 V3 suits entry workloads that need more drive bays and can live with 8 cores; and the R260 suits Dell iDRAC9 estates that want the 12-core option and do not need redundant power supplies.

Dell PowerEdge R260
Best for: Dell iDRAC9-managed SMB and near-edge sites that want up to 12 cores and can run without redundant power supplies.
HPE ProLiant DL20 Gen11
