1U 10-Bay Rack Server

The Dell PowerEdge R650xs is a 1U rack server fitted with two Intel Xeon Silver 4316 processors running at 2.3 GHz with 3.4 GHz turbo. It provides 20 cores per CPU and ships with 64 GB of DDR4 2666 MHz registered ECC memory across four 16 GB modules.

Suits dense virtualisation and cloud workloads

This configuration targets environments that need high core counts and fast local storage in a single rack unit. Buyers who require GPU acceleration for AI training or larger memory footprints beyond 1 TB should evaluate alternative platforms.

PERC H745 RAID controller with 4 GB NV cache

The integrated Dell PERC H745 supports RAID 0, 1, 5, 6, 10, 50 and 60 and includes a battery-backed 4 GB non-volatile cache. Ten 600 GB 10K SAS drives are pre-installed, delivering 12 Gb/s throughput for the storage array.

Questions about this item

Should I pick the 10-bay 2.5" model or a different bay count for this R650xs?

This unit ships with 10 bays populated by 600 GB 10K SAS drives on a PERC H745 controller, giving you 6 TB raw in RAID 5 or 6 with 4 GB NV cache and battery backup.

How does the 2.3 GHz base clock with 3.4 GHz turbo on the Xeon Silver 4316 translate to real-world throughput?

Each of the two 20-core CPUs runs at 2.3 GHz base and boosts to 3.4 GHz, so heavily threaded workloads such as virtualization or database services can sustain high frequencies across all 40 cores.

What does the OCP 3.0 quad-port 1 GbE card cap at in practice?

The Broadcom 5720 OCP 3.0 adapter provides four 1 GbE ports, limiting each link to 1 Gbps full-duplex; aggregate throughput depends on switch configuration and teaming mode.
