Built for Virtualization and Databases

The Dell PowerEdge R640 is a 1U rackmount server equipped with dual Intel Xeon Silver 4114 processors running at 2.20GHz, providing 20 physical cores total. It ships with 256GB of DDR4 ECC Registered memory and a PERC H740P RAID controller supporting SAS drives. Eight 2.5-inch hot-swap drive bays are included without drives, allowing flexible storage configuration. Networking comprises two 10GbE and two 1GbE ports.

Suits Consolidation; Not GPU or High-Core Workloads

This server fits organisations consolidating virtual machines, hosting SQL or Oracle databases, or building private cloud infrastructure on a dense platform. Buyers who require GPU acceleration, larger memory footprints beyond 3TB, or higher core counts per socket should look at other platforms. The integrated graphics and maximum two-socket design limit visual compute and vertical scaling.

8-Bay 2.5-Inch Chassis Defines Storage Limits

The 8-bay 2.5-inch front chassis is the single specification that decides fit: it caps the number of hot-swap drives at eight and excludes 3.5-inch drives. If your deployment needs more drive slots or larger form-factor disks, this chassis will not work. The PERC H740P controller manages RAID 0, 1, 5, 6, 10, 50 and 60 across those bays.

Questions about this item

What drive trays come with the R640 so I can add storage?

The server includes ten 2.5" hot-swap trays for the eight-bay chassis.

Will my existing 12Gb/s SAS cables and backplanes work with the PERC H740P controller?

Yes, the H740P is a 12Gb/s SAS RAID controller compatible with standard SAS infrastructure.

How do I confirm the dual Xeon Silver 4114 CPUs and 256GB DDR4 are recognised after first boot?

Check the system BIOS or iDRAC interface; both should show 20 total cores at 2.2GHz and 256GB DDR4 ECC Registered memory.
