About the XE8545

The Dell PowerEdge XE8545 is an enterprise 4U rack server engineered for computing and virtualization workloads. Powered by 2 AMD EPYC 7002 and 7003 Series Processors (up to 2x 64 cores, 280W cTDP) across 32 memory slots supporting up to 4096GB DDR4-3200 RDIMM / LRDIMM, the XE8545 balances throughput and memory capacity. In Dell's server catalog, the XE8545 was followed by the POWEREDGE-XE8640, positioned alongside rival systems including NVIDIA-DGX-A100, SUPERMICRO-GPU-4U.

Options and compatibility

Processor support on the XE8545 utilizes 2 Socket SP3 sockets with thermal heatsinks matching CPU power envelopes. System memory slots on the XE8545 require DDR4-3200 RDIMM / LRDIMM modules, and mixing RDIMM with LRDIMM memory is not supported. The XE8545 chassis utilizes DXD9H (2.5-inch SFF) drive trays across its 2.5-inch drive backplane bays. Networking on the XE8545 uses OCP 3.0 mezzanine slot, and expansion cards install into Up to 4 PCIe Gen4 slots risers.

How to identify it

Physical identification of the XE8545 is verified by the 15th-generation high-airflow front security bezel with the XE8545 badge on the front chassis ear. The pull-out information tag on the XE8545 control panel displays the 7-character Dell Service Tag and default login credentials. In iDRAC9 Gen15, the server identifies as XE8545 with active firmware, slot mapping, and power telemetry.

Buying used

When evaluating a pre-owned XE8545, inspect the Socket SP3 CPU socket pins for damage and ensure retention clips are intact. Run Dell ePSA diagnostics across all 32 memory slots of the XE8545 to verify zero uncorrectable ECC faults under load. Verify that redundant power supplies in the XE8545 match in wattage and that iDRAC9 Gen15 Enterprise remote console is enabled. Ensure required XE8545 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).
