Built for Virtualisation and Data Workloads

The Dell PowerEdge R640 8B is a rackmount server equipped with two Intel Xeon Gold 5122 processors running at 3.60GHz with four cores each. It ships with 256GB of DDR4 ECC Registered memory and supports up to 3TB total capacity. Eight 2.5-inch hot-swap drive bays with trays are included, while storage drives must be supplied separately. A PERC H740P controller provides 12Gb/s SAS connectivity for the chosen drives.

Sustained Performance with H740P and 10GbE

Dual 10GbE X540 and 1GbE I350 network interfaces maintain throughput for virtual desktop infrastructure, SQL Server and analytics workloads. The H740P RAID controller manages sustained I/O across the eight-bay chassis without relying on a short burst. Integrated graphics handle console output while the CPUs focus on compute tasks. The platform is designed for consistent speed in high-availability environments.

Check Rack Space and Drive Selection

Verify that your rack can accommodate a 1U form factor and that power and cooling provisions match the unit's requirements. Because no drives are included, confirm the SAS SSD or HDD models you intend to install are compatible with the H740P controller. Ensure your networking infrastructure supports 10GbE or 1GbE cabling to use the onboard dual interfaces. Operating system installation media must be provided separately.

Questions about this item

How much power do the dual Xeon Gold 5122 CPUs draw under full load in this R640?

The two Intel Xeon Gold 5122 processors each run at 3.6GHz with four cores, and the R640 chassis is designed to cool that thermal profile continuously in a rack.

Which drive trays and controller are included so I can add storage myself?

Eight 2.5-inch hot-swap trays ship with the server and the PERC H740P RAID controller supports 12Gb/s SAS drives you install.

Can the onboard X540 10GbE and I350 1GbE ports connect to my existing network gear?

The X540 and I350 controllers provide standard Ethernet interfaces compatible with common switches and cabling used in rack environments.
