1U rack server with dual Xeon Silver 4210

The Dell PowerEdge R640 is a 1U rack-mount server populated with two Intel Xeon Silver 4210 processors running at 2.2 GHz. It ships with 256 GB of DDR4 ECC registered memory and a PERC H740P RAID controller. The 10 SFF chassis accepts up to ten 2.5-inch SATA drives, though no drives are installed. Remote management is provided by iDRAC9 Enterprise.

Suits virtualisation hosts needing dense CPU cores

This configuration fits buyers who want a ready-to-run virtualisation host with twenty physical cores and room for 7.68 TB of RAM. It is not for buyers who need GPU acceleration, Fibre Channel connectivity, or a tower form factor. The integrated graphics and dual 10 GbE ports cover basic display and network needs without extra cards.

Ten 2.5-inch drive bays with PERC H740P RAID

The single specification that decides fit is the ten-bay 2.5-inch backplane paired with the H740P controller. If your deployment requires more than ten drives, 3.5-inch bays, or a different RAID engine, this chassis will not meet the requirement.

Questions about this item

What does the 2.2 GHz clock on the Xeon Silver 4210 mean for real workloads?

The base frequency of 2.2 GHz runs across all 10 cores per processor, giving predictable throughput for virtualisation and database tasks.

How does the PERC H740P controller limit the SATA drives?

The PERC H740P manages up to ten 2.5-inch SATA bays with hardware RAID 0, 1, 5, 6, 10, 50, 60 and a 2 GB cache.

What clearance does the 36 x 24 x 10 inch chassis need for installation?

The 1U high, 36-inch deep chassis requires a four-post rack with at least 36 inches of usable depth and front-to-rear airflow.
