About the R250

The Dell PowerEdge R250 is an enterprise 1U rack server engineered for computing and virtualization workloads. Powered by 1 Intel Xeon E-2300 Series or Intel Pentium Processors (up to 8 cores, 95W TDP) across 4 memory slots supporting up to 128GB DDR4-3200 ECC UDIMM, the R250 balances throughput and memory capacity. In Dell's server catalog, the R250 succeeded the POWEREDGE-R240, positioned alongside rival systems including PROLIANT-DL20-GEN10-PLUS.

Options and compatibility

Processor support on the R250 utilizes 1 LGA1200 sockets with thermal heatsinks matching CPU power envelopes. System memory slots on the R250 require DDR4-3200 ECC UDIMM modules, and mixing RDIMM with LRDIMM memory is not supported. The R250 chassis utilizes X7K8W (3.5-inch LFF) drive trays across its 3.5-inch storage bays. Networking on the R250 uses OCP 3.0 mezzanine slot, and expansion cards install into Up to 2 PCIe Gen4 slots risers.

How to identify it

Physical identification of the R250 is verified by the 15th-generation high-airflow front security bezel with the R250 badge on the front chassis ear. The pull-out information tag on the R250 control panel displays the 7-character Dell Service Tag and default login credentials. In iDRAC9 Gen15, the server identifies as R250 with active firmware, slot mapping, and power telemetry.

Buying used

When evaluating a pre-owned R250, inspect the LGA1200 CPU socket pins for damage and ensure retention clips are intact. Run Dell ePSA diagnostics across all 4 memory slots of the R250 to verify zero uncorrectable ECC faults under load. Verify that redundant power supplies in the R250 match in wattage and that iDRAC9 Gen15 Enterprise remote console is enabled. Ensure required R250 drive caddies and bracket accessories are present.

Match the speed: 16Gb and 32Gb FC HBAs, switches and array ports work together, and each generation also runs one or two speeds below its own (a 32Gb port runs at 16Gb and 8Gb).

12Gb SAS uses Mini-SAS HD (SFF-8644) connectors; older 6Gb gear uses Mini-SAS (SFF-8088). Adapter cables exist, but the link runs at the slower speed.
