DELL PowerEdge R660xs 1U rack server, 2×Xeon, 16 DDR5 slots, 1.5 TB max

Dense 1U rack server for virtualization and HPC

The Dell PowerEdge R660xs is a 1U rackmount chassis built for virtualization, cloud, scale-out database and HPC workloads. It accepts up to two Intel Xeon Scalable processors and provides sixteen DDR5 DIMM slots with a maximum capacity of 1.5 TB. No CPUs or memory modules are installed, so the buyer must populate both.

Flexible front and rear drive bays

The front panel supports either four 3.5-inch SAS or SATA drives up to 96 TB total, or ten 2.5-inch SAS, SATA or NVMe drives up to 153.6 TB total. An additional two 2.5-inch SAS, SATA or NVMe bays at the rear add up to 15.2 TB. No drives are included; the configuration chosen determines both capacity ceiling and interface mix.

Sixteen DDR5 slots set the memory ceiling

Registered ECC DDR5 DIMMs running at up to 5200 MT/s are the only supported memory type, and the sixteen slots cap total system memory at 1.5 TB. Buyers needing more memory capacity or a different memory generation must select another platform.
