Rack Server for Virtualisation Workloads

The Dell PowerEdge R640 is a 1U rack server equipped with two Intel Xeon Silver 4214 processors running at 2.2GHz, providing 24 cores total. It ships with 256GB of DDR4 ECC registered memory and a PERC H740P RAID controller. The 4LFF chassis supports up to four 3.5-inch SATA drives, though no drives are installed. Remote management is handled by iDRAC9 Enterprise.

Suited for Memory-Intensive Applications

This configuration suits environments that need high core counts and large memory capacity, such as virtualisation hosts, database servers, or compute clusters. The dual 750W power supplies provide redundancy. Buyers who need GPU acceleration, front-access high-speed bays, or a tower form factor should evaluate other platforms.

256GB DDR4 Memory Installed

The system arrives with 256GB of DDR4 memory installed across the available DIMM slots. Maximum supported capacity reaches 7.68TB when fully populated with compatible modules. This installed amount determines whether the server can immediately run your intended workloads or requires additional memory investment before deployment.

Questions about this item

How many 3.5-inch drive bays can I populate later, and which controller manages them?

The chassis accepts up to four 3.5-inch drives and the PERC H740P controller handles RAID for those bays.

What thermal or power ceiling will the dual Xeon Silver 4214 CPUs hit first during continuous workloads?

Two 750 W supplies power the pair of 2.2 GHz 12-core processors, so the platform power budget is the first limit under sustained load.

How loud are the fans when the R640 runs 24/7 with 256 GB DDR4 and the 10 GbE 562T adapter active?

The 1U rack design uses high-speed fans that produce noticeable airflow noise in a quiet room during all-day operation.
