About the R750

The Dell PowerEdge R750 is an enterprise 2U rack server engineered for computing and virtualization workloads. Powered by 2 Intel Xeon Scalable 3rd Gen (Ice Lake across 32 memory slots supporting up to 8192GB DDR4-3200 RDIMM / LRDIMM, the R750 balances throughput and memory capacity. In Dell's server catalog, the R750 succeeded the POWEREDGE-R740 and was followed by the POWEREDGE-R760, positioned alongside rival systems including PROLIANT-DL380-GEN10-PLUS, THINKSYSTEM-SR650-V2.

Options and compatibility

Processor support on the R750 utilizes 2 LGA4189 (Socket P+) sockets with thermal heatsinks matching CPU power envelopes. System memory slots on the R750 require DDR4-3200 RDIMM / LRDIMM modules, and mixing RDIMM with LRDIMM memory is not supported. Front backplanes on the R750 accommodate either DXD9H (2.5-inch SFF) or X7K8W (3.5-inch LFF) trays based on chassis option. Networking on the R750 uses OCP 3.0 mezzanine slot, and expansion cards install into Up to 8 PCIe Gen4 slots risers.

How to identify it

Physical identification of the R750 is verified by the 15th-generation high-airflow front security bezel with the R750 badge on the front chassis ear. The pull-out information tag on the R750 control panel displays the 7-character Dell Service Tag and default login credentials. In iDRAC9 Gen15, the server identifies as R750 with active firmware, slot mapping, and power telemetry.

Buying used

When evaluating a pre-owned R750, inspect the LGA4189 (Socket P+) CPU socket pins for damage and ensure retention clips are intact. Run Dell ePSA diagnostics across all 32 memory slots of the R750 to verify zero uncorrectable ECC faults under load. Verify that redundant power supplies in the R750 match in wattage and that iDRAC9 Gen15 Enterprise remote console is enabled. Ensure required R750 drive caddies and bracket accessories are present.

Works together

How the Dell PowerEdge R750 connects to servers, storage and the network: 4 ways, with the parts and products on each path.

Fibre Channel SANiSCSI and NVMe/TCP over EthernetDirect-attached SASFile storage (NFS and SMB)

Fibre Channel SAN

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).

Fibre Channel SAN: how it fits together

iSCSI and NVMe/TCP over Ethernet

Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

iSCSI and NVMe/TCP over Ethernet: how it fits together

Direct-attached SAS

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.

File storage (NFS and SMB)

Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.
