Dell PowerEdge R650xs 1U Server

The Dell PowerEdge R650xs is a 1U rack server system built for data center deployment. It ships with two Intel Xeon Silver 4310 processors running at 2.1GHz with 12 cores each. The system includes 256GB of DDR4 memory installed across eight 32GB modules. Eight 1.8TB SAS hard drives and a PERC H745 RAID controller provide the storage foundation.

Suits virtualisation and dense compute

This server suits teams running virtualisation, cloud infrastructure or dense analytics workloads in a 1U footprint. Dual 1400W power supplies and iDRAC9 Enterprise support high-availability requirements. Buyers needing GPU acceleration for AI training should look elsewhere as this configuration has no AI features. Organisations requiring NVMe boot drives or larger memory capacity than 256GB installed will need a different configuration.

PERC H745 RAID with 4GB NV cache

The storage controller is a Dell PERC H745 with 4GB non-volatile cache and battery backup. It supports RAID levels 0, 1, 5, 6, 10, 50 and 60 across the eight 2.5-inch drive bays. This controller choice determines the data protection and performance profile for the installed 1.8TB 10K SAS drives. The OCP 3.0 quad-port 1GbE network card handles connectivity.

Questions about this item

Should I choose the 256 GB DDR4 configuration or add more memory up to the 1 TB limit?

The server arrives with 256 GB of DDR4 2666 MHz registered ECC memory installed across 8 slots; the platform supports up to 1 TB when all 16 DIMM slots are populated.

What does the 2.1 GHz base and 3.3 GHz turbo on the Xeon Silver 4310 mean for sustained workloads?

Each of the two installed Silver 4310 CPUs runs at 2.1 GHz base clock and can boost to 3.3 GHz, providing 12 cores per processor for virtualization, cloud and dense analytics tasks.

How does the SAS 12 Gb/s interface on the H745 controller affect drive performance?

The PERC H745 connects the eight 1.8 TB 10K SAS drives at 12 Gb/s and supports RAID 0, 1, 5, 6, 10, 50 and 60 with 4 GB NV cache and battery backup.
