Dell PowerEdge R650xs 1U Rack Server

The Dell PowerEdge R650xs is a 1U rack server built for dense data centre deployments. It ships with two Intel Xeon Silver 4316 processors running at 2.3GHz with a 3.4GHz turbo frequency. The system includes 64GB of DDR4 2666MHz registered ECC memory and a PERC H745 RAID controller with 4GB NV cache. Dual 1400W platinum power supplies provide redundant hot-swap power.

Who this suits and who should look elsewhere

This server fits virtualisation clusters, cloud infrastructure and high-performance computing workloads that need dual-socket compute in a single rack unit. The eight 2.5-inch SAS/SATA trays support mixed drive populations. Buyers who require GPU acceleration or more than 1TB of memory should consider other platforms. The 10GbE SFP+ OCP card handles high-throughput networking.

Single specification that decides fit

The LGA 4189 socket and Intel Xeon Silver 4316 20-core processors define the compute ceiling. Memory scales to 1TB across 16 DDR4 slots at 3200 MT/s. Storage uses the H745 controller for RAID 0, 1, 5, 6, 10, 50 and 60. iDRAC9 Enterprise enables full remote lifecycle management.

Questions about this item

Does the R650xs ship with drive trays and rails, or must I order them separately?

The server includes eight 2.5" SAS/SATA trays, ready rails and a front bezel, so no extra trays or rails are needed for the supported bays.

Which Xeon Silver 4316 configuration matches my workload — the 2.3 GHz base or 3.4 GHz turbo figure?

Each of the two installed Silver 4316 processors runs at 2.3 GHz base with a 3.4 GHz turbo across its 20 cores, giving 40 cores total for multi-threaded tasks.

What real throughput can I expect from the dual-port 10GbE OCP 3.0 card in a live rack?

The Broadcom 57412 provides two 10 GbE SFP+ ports on an OCP 3.0 module, delivering up to 10 Gbit/s per port for east-west traffic or storage links.
