1U Dual-Socket Server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data center computing. It ships with two Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores. The system includes 512 GB of DDR4 2666 MHz registered ECC memory across 16 modules. Two 400 GB SATA SSDs and a PERC H730P RAID controller provide the initial storage foundation.

Target Workloads and Limits

This server suits organisations running virtualisation clusters, database instances or high-performance computing tasks that benefit from 32 total cores and large memory capacity. The quad-port network daughter card delivers two 1 GbE and two 10 GbE SFP+ connections for flexible fabric integration. Buyers needing more than two processors, GPU acceleration or additional drive bays beyond the eight 2.5-inch slots should evaluate larger platforms.

Memory Capacity Decides Fit

The installed 512 GB of DDR4 memory occupies 16 of the 24 available DIMM slots, leaving room to expand toward the 3 TB maximum supported by the Intel C620 chipset. Confirm that your application licensing and workload footprint align with this starting capacity before deployment.

Questions about this item

Will the LGA 3647 Xeon Gold 6142 CPUs work with my existing DDR4 2666 MHz registered ECC modules?

Yes, the server uses DDR4 2666 MHz registered ECC memory and has 24 slots supporting up to 3 TB, so your compatible modules can be installed alongside the 512 GB already fitted.

How can I verify the PERC H730P controller and both 400 GB SSDs are operating correctly after installation?

During boot, open the H730P BIOS utility (Ctrl+R) to confirm the controller sees both 400 GB SATA SSDs, then check iDRAC9 Enterprise storage health for optimal RAID status and drive SMART data.

Does the shipment include SFP+ transceivers for the X520 10 GbE ports, or must I purchase them separately?

The box contains the server, X520/I350 quad-port network daughter card, iDRAC9 Enterprise, two 750 W PSUs, rails and bezel; SFP+ transceivers for the 10 GbE ports are not included and must be bought separately.
