Dell PowerEdge R640 4LFF Dual Xeon

This Dell PowerEdge R640 is a 1U rack-mount server system built for dense compute workloads. It ships with two Intel Xeon Silver 4214R processors, each running at 2.4 GHz with 12 cores and 16.5 MB cache. The chassis provides four 3.5-inch drive bays and includes a PERC H740P RAID controller for SATA storage. Remote management is handled by iDRAC9 with an Enterprise licence.

Virtualisation hosts needing high core count

The dual-socket design delivers 24 total cores and 256 GB of DDR4 ECC registered memory, expandable to 7.68 TB. Dual 750 W power supplies and a 10 GbE two-port 562T adapter support high-availability clusters. Buyers who need GPU acceleration or more than four 3.5-inch drive bays should look elsewhere. The integrated graphics only covers basic console output.

PERC H740P RAID controller for SATA arrays

The installed PERC H740P controller determines which drive types and RAID levels are supported. No drives are included, so the buyer must select compatible SATA disks to match the four-bay backplane. This single component decides whether the server can boot the intended array configuration.

Questions about this item

How do I verify the dual Xeon Silver 4214R CPUs and 256GB DDR4 are recognised after first boot?

Enter the BIOS or iDRAC9 interface; both should show two 2.4 GHz 12-core processors and 16 x 16GB DDR4 modules totalling 256GB.

What components are included and which must be sourced separately?

The chassis includes two Xeon Silver 4214R CPUs, 256GB DDR4 ECC RAM, a PERC H740P RAID controller, dual 750W supplies, a 10GbE 562T adapter and iDRAC9 Enterprise; 3.5" SATA drives and rail kit are not included.

Which drive-bay version suits a 4-bay 3.5" SATA deployment?

Choose the 4LFF chassis — it provides exactly four 3.5" bays wired to the PERC H740P for SATA drives.
