Purpose-Built Rack Server

The Dell PowerEdge R640 4LFF chassis houses a single Intel Xeon Silver 4216 processor running at 2.1GHz with 16 cores and 22MB cache, paired with 256GB of DDR4 ECC registered memory across sixteen 16GB modules. It includes a PERC H740P RAID controller and dual 750W power supplies in a 1U form factor measuring 36 by 24 by 10 inches and weighing 40 units. The system arrives with firmware updated and no drives installed.

Fit and Limitations

This configuration suits workloads that need up to four 3.5-inch SATA drive bays, integrated graphics, 10GbE networking via a 562T adapter, and remote management through iDRAC9 Enterprise. It also supports expansion to a second processor and up to 7.68TB of DDR4 memory. Buyers who require the second processor populated immediately or who need more than four drive bays should evaluate other platforms.

Deciding Specification

The chassis provides exactly four 3.5-inch drive bays wired for SATA through the PERC H740P controller, which determines the maximum number of internal drives and the storage interface available.

Questions about this item

Do I need to buy any 3.5" SATA drives to use the four drive bays?

Yes, the four 3.5" bays are empty and require SATA hard drives or SSDs to provide storage capacity.

Will the PERC H740P RAID controller manage drives I move from an older Dell server?

The PERC H740P supports SATA drives from earlier Dell systems, but you should verify the specific drive models are on the controller compatibility list.

How can I confirm the 256GB DDR4 memory is recognised after installation?

Check the iDRAC9 Enterprise interface or the BIOS System Information screen; both will display the total installed memory as 256GB.
