DELL PowerEdge R650xs 1U Rack Server 2x Xeon Silver 4316 2.3GHz 20 Core 128GB DDR4 H745 8 Bay 2.5" 2x 1400W

Compact 1U rack server for dense compute

The Dell PowerEdge R650xs is a 1U rack server built for space-constrained data centres. It ships with two Intel Xeon Silver 4316 processors running at 2.3 GHz with a 3.4 GHz turbo frequency. Each CPU provides 20 cores for a total of 40 threads across the dual-socket platform. The system includes 128 GB of DDR4 2666 MHz registered ECC memory across eight DIMM slots. Redundant hot-swap 1400 W platinum power supplies and a front bezel with ready rails complete the package.

Virtualisation hosts and cloud nodes.

This configuration suits organisations deploying virtualisation clusters, cloud infrastructure or high-performance computing workloads that benefit from high core counts in a 1U form factor. The PERC H745 controller with 4 GB NV cache supports RAID 0, 1, 5, 6, 10, 50 and 60 across eight 2.5-inch SAS or SATA drive bays. Dual-port 10 GbE SFP+ networking and iDRAC9 Enterprise simplify remote management. Buyers who need GPU acceleration for AI or machine learning tasks should look at alternative platforms that provide PCIe expansion for graphics cards.

Eight 2.5-inch SAS/SATA bays define storage limits

The single specification that decides fit is the eight-bay 2.5-inch chassis limited to SAS and SATA interfaces. NVMe drives are not supported on this backplane, so all-flash arrays requiring NVMe throughput cannot be deployed here. Maximum memory capacity reaches 1 TB across 16 DDR4 slots, but only 128 GB is installed today. The LGA 4189 sockets accept a second processor of the same generation if the single-CPU configuration is ordered elsewhere.
