2U Rack Server for Virtualisation

This Dell PowerEdge R640 is a 2U rackmount server built for business workloads such as virtualisation, databases, file storage and application hosting. Two Intel Xeon Gold 6148 processors deliver 40 cores in total, running at 2.4 GHz each. The system includes 512 GB of DDR4 memory and eight 600 GB 10K SAS drives managed by an H730P controller.

Suited for Multi-VM Environments, Not GPU Compute

Organisations running multiple virtual machines, heavy database instances or large backup sets will benefit from the high core count, large memory capacity and fast SAS storage. The integrated GPU and lack of dedicated graphics expansion make it unsuitable for workloads that require GPU acceleration or visual rendering. Buyers needing more than eight 2.5-inch drive bays or a different drive interface will also need a different chassis.

512 GB DDR4 Installed, Expandable to 3 TB

The server ships with 512 GB of DDR4 memory installed across its DIMM slots. Maximum supported capacity is 3 TB, allowing substantial growth for memory-intensive applications. The LGA3647 socket platform is fully populated with two processors, so no further CPU upgrades are possible.

Questions about this item

Do I need to add any extra DDR4 modules for the 512GB configuration to run, or is it complete as shipped?

The server ships with 512GB of DDR4 already installed, so no additional memory is required for it to operate.

Can I keep using my existing SAS drives alongside the eight 600GB SAS drives that come installed?

Yes, the 8-bay 2.5-inch chassis and H730P controller support additional SAS drives in any empty bays you populate.

How can I confirm both Xeon Gold 6148 processors are detected and all 40 cores are active after first boot?

Enter the BIOS or iDRAC interface; the processor information screen will show two CPUs with a combined 40 cores running at 2.4GHz.
