About the R740xd

The Dell PowerEdge R740xd is an enterprise 2U rack server engineered for computing and virtualization workloads. Powered by 2 Intel Xeon Scalable 1st Gen (Skylake) and 2nd Gen (Cascade Lake) across 24 memory slots supporting up to 3072GB DDR4-2666 / DDR4-2933 RDIMM / LRDIMM, the R740xd balances throughput and memory capacity. In Dell's server catalog, the R740xd succeeded the POWEREDGE-R730XD and was followed by the POWEREDGE-R750, positioned alongside rival systems including PROLIANT-DL380-GEN10.

Options and compatibility

Processor support on the R740xd utilizes 2 LGA3647 (Socket P0) sockets with thermal heatsinks matching CPU power envelopes. System memory slots on the R740xd require DDR4-2666 / DDR4-2933 RDIMM / LRDIMM modules, and mixing RDIMM with LRDIMM memory is not supported. Front backplanes on the R740xd accommodate either DXD9H (2.5-inch SFF) or X7K8W (3.5-inch LFF) trays based on chassis option. Networking on the R740xd uses Network Daughter Card (NDC), and expansion cards install into Up to 8 PCIe Gen3 slots risers.

How to identify it

Physical identification of the R740xd is verified by the 14th-generation silver-gray brushed aluminum honeycomb bezel with the R740xd badge on the front chassis ear. The pull-out information tag on the R740xd control panel displays the 7-character Dell Service Tag and default login credentials. In iDRAC9, the server identifies as R740xd with active firmware, slot mapping, and power telemetry.

Buying used

When evaluating a pre-owned R740xd, inspect the LGA3647 (Socket P0) CPU socket pins for damage and ensure retention clips are intact. Run Dell ePSA diagnostics across all 24 memory slots of the R740xd to verify zero uncorrectable ECC faults under load. Verify that redundant power supplies in the R740xd match in wattage and that iDRAC9 Enterprise remote console is enabled. Ensure required R740xd drive caddies and bracket accessories are present.

Works together

How the Dell PowerEdge R740xd 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.
