Dual Xeon Gold 6148 Server

The Dell PowerEdge R640 is a 1U rackmount server system built for business workloads such as virtualization, databases, and application hosting. It ships with two Intel Xeon Gold 6148 processors running at 2.40GHz, delivering a total of 40 cores for multi-threaded performance. The system includes 256GB of DDR4 memory and supports a maximum capacity of 3TB. This new unit is configured without installed drives, leaving the 10-bay chassis ready for your storage selection.

Virtualization and Database Focus

This configuration suits IT teams deploying virtualized environments, file storage, or backup infrastructure in a data centre or server room. The 10-bay front panel supports eight NVMe-capable 2.5-inch bays for high-speed storage arrays. Buyers who require pre-installed operating systems or drives should look elsewhere, as the server arrives without an OS or storage media. Workloads needing GPU acceleration are not supported by the integrated graphics controller.

Rackmount Installation Notes

The 60-unit weight requires two people or a mechanical lift for safe rack mounting on standard square-hole or threaded rails. Cable management arms and rail kits are not confirmed in the supplied specification, so verify inclusion before installation day. The LGA3647 sockets are fully populated, preventing future CPU upgrades without removing an existing processor. Memory expansion uses DDR4 RDIMM or LRDIMM modules only; other generations will not fit the slots.

Questions about this item

What drive form factor and interface does the 10-bay backplane accept?

The backplane holds ten 2.5-inch drives and eight of those bays are NVMe-capable.

Will the dual Xeon Gold 6148 CPUs work with my existing LGA3647 socket motherboard?

Yes, both processors use the LGA3647 socket, matching the motherboard already in the R640.

How can I confirm the 40 cores and 256 GB DDR4 are recognised after installation?

Check the BIOS POST screen or iDRAC inventory; both will list 40 logical cores and 256 GB of DDR4 memory.
