Target workload

This Dell PowerEdge R640 rack server arrives with two Xeon Silver 4210 processors running at 2.2GHz and 768GB of DDR4 memory, delivering 20 cores and 40 threads for virtualization, database or compute clusters that need dense memory capacity in a 1U form factor.

Buyer fit

The four 3.5-inch drive bays and PERC H740P RAID controller suit teams building local storage arrays on SATA drives, while the integrated iDRAC9 Enterprise licence provides full remote lifecycle management. Buyers who require more than four drive bays or a different drive form factor need a different chassis.

Deciding specification

Maximum supported memory reaches 7.68TB across the platform, so the installed 768GB represents ten percent of the ceiling and leaves headroom for future DIMM upgrades without replacing the server.

Questions sur cet article

How many DDR4 memory slots remain free for future upgrades?

The system supports up to 7.68 TB of DDR4 memory, so additional capacity can be added beyond the installed 768 GB.

Will the dual Xeon Silver 4210 processors hit their thermal limit before the 750 W power supplies do?

Each CPU has a 10-core design at 2.2 GHz, and the dual 750 W supplies provide headroom for sustained loads.

How loud are the fans when the R640 runs 24/7 with the PERC H740P controller active?

The 1U chassis uses high-speed fans to cool the dual processors and RAID controller, so expect noticeable airflow noise in a quiet room.
