DELL PowerEdge R650xs 1U rack server 2x Xeon Silver 4314 2.4GHz 16C 256GB DDR4 10x 600GB SAS H745 2x 1400W

Server identity

The Dell PowerEdge R650xs is a 1U rack server built on the 15th Generation PowerEdge platform. It ships with dual Intel Xeon Silver 4314 processors, 256GB of DDR4 2666MHz registered ECC memory and a PERC H745 RAID controller with 4GB NV cache. Ten 600GB 10K SAS drives and a dual-port 10GbE SFP+ OCP 3.0 network card are installed. Dual 1400W platinum power supplies, iDRAC9 Enterprise, rails and bezel complete the unit.

Fit and limits

This configuration suits virtualisation hosts, dense cloud nodes and analytics clusters that need high core counts and fast local storage in a single rack unit. The fixed 10-bay 2.5-inch chassis and pre-populated drive set leave no room for additional spinners or larger 3.5-inch media. Buyers who need more storage bays, GPU acceleration or a different drive interface should evaluate other platforms.

Deciding specification

The PERC H745 controller with 4GB non-volatile cache and battery backs RAID 0, 1, 5, 6, 10, 50 and 60 across the ten 600GB SAS drives. This combination of controller cache, RAID breadth and drive speed determines whether the array meets the write-throughput and redundancy demands of the target workload.
