Dual Xeon Silver 4210 Server

The Dell PowerEdge R640 is a 1U rack server equipped with two Intel Xeon Silver 4210 processors running at 2.2GHz. Each CPU provides ten cores and 13.75 MB of cache, delivering twenty threads for parallel workloads. It targets organisations that need dense compute in a standard rack footprint. The system ships with 1TB of DDR4 ECC registered memory installed.

Eight-Bay SAS Chassis Limits

The 8SFF chassis accepts up to eight 2.5-inch drives connected through the Dell PERC H740P RAID controller over a SAS interface. No drives are installed, so storage capacity and redundancy depend entirely on the drives added. Network connectivity is provided by a dual-port 10GbE 562T adapter. Remote management uses iDRAC9 with an Enterprise licence for out-of-band control.

Memory Headroom to 7.68TB

The installed 1TB of DDR4 memory occupies a portion of the 7.68TB maximum supported capacity, leaving substantial room for expansion as workloads grow. Two 750W power supplies provide redundancy for the configured components. Buyers who need internal storage must add drives separately, and those requiring GPU acceleration will find only integrated graphics available.

Questions about this item

Which storage capacity should I select for the eight 2.5" bays?

The server ships without drives; choose SAS HDDs or SSDs that match the PERC H740P controller and the 2.5-inch bay count.

What does the 2.2 GHz Xeon Silver 4210 rating mean when both 10-core CPUs are installed?

You get twenty total cores at 2.2 GHz base frequency with 13.75 MB cache per processor for parallel workloads.

How does the PERC H740P SAS controller limit the drive array?

It manages up to eight SAS drives in hardware RAID 0, 1, 5, 6, 10, 50 or 60 with onboard cache.
