1U Dual-Socket Server for Dense Compute

The Dell PowerEdge R650xs is a 1U rack server built for data-centre workloads that need high core density in minimal rack space. It ships with two Intel Xeon Silver 4316 processors, each running at 2.3GHz with 20 cores and a 3.4GHz turbo frequency. The platform targets virtualisation, cloud infrastructure and dense analytics clusters.

512GB DDR4 Registered ECC Memory

The system includes 512GB of DDR4 2666MHz registered ECC memory across 16 slots, using 32GB modules. This capacity supports large virtual-machine densities and in-memory databases without exceeding the 1TB maximum. Buyers who need more memory than 512GB must add modules themselves, as the configuration does not leave headroom beyond the installed amount.

Dual 1400W Platinum Power Supplies

Redundant hot-swap 1400W platinum-efficiency power supplies handle the 20-core CPUs, eight 1.8TB 10K SAS drives and the PERC H745 controller under typical load. The 1U chassis uses high-speed fans to move air front-to-rear; acoustic output rises with sustained heavy utilisation. Power draw scales with CPU turbo and drive activity, so rack PDU capacity should match the dual-supply rating.

Questions about this item

What does the 2.3 GHz base clock on the Xeon Silver 4316 mean for real-world throughput?

Each of the two installed 20-core processors runs at 2.3 GHz base and can boost to 3.4 GHz, giving 40 total cores for parallel workloads such as virtualization and database serving.

How does the 12 Gb/s SAS link on the PERC H745 controller limit the eight 1.8 TB drives?

The controller connects to the backplane at 12 Gb/s per lane, so sustained throughput is capped by that SAS interface rather than by the individual 10K drive speeds.

What physical space and mounting hardware does the 1U chassis need?

The server fits a standard 1U slot and ships with ready rails and a front bezel for tool-less installation in a 4-post rack.
