10-Bay Rack Server

The Dell PowerEdge R640 is a 1U rackmount server built for business workloads such as virtualization, databases and application hosting. It ships with dual Intel Xeon Gold 6148 processors running at 2.40 GHz, 40 total cores and 128 GB of DDR4 memory. Ten 2.5-inch bays are populated with 600 GB 10K SAS drives. The unit weighs 60 kg and uses an LGA3647 socket platform.

Virtualization-Focused Teams

This configuration suits IT teams running multiple virtual machines, heavy database instances or backup services that benefit from high core counts and fast SAS storage. Buyers who need more drive bays, larger drive capacities or a different storage interface must choose a different chassis. Workloads that rely on GPU acceleration or require operating-system licensing included will not be met by this unit.

Dual Xeon Gold 6148 CPUs

The two Gold 6148 processors deliver 40 cores at 2.40 GHz, setting the performance ceiling for compute-heavy tasks. Memory can be expanded to 3 TB of DDR4 across the available slots. The ten-bay 2.5-inch SAS backplane fixes the storage topology for this model.

Questions about this item

How do I install the 10x 2.5" SAS drives into the 10B front bays, and what step is often missed?

Slide each 600GB drive into a bay until the latch clicks; the step often missed is fully engaging the release lever so the drive seats on the backplane.

What maintenance will the 128GB DDR4 memory need later?

DDR4 modules rarely fail; plan to reseat or replace sticks only if ECC errors appear in the system log after years of operation.

What limit appears first when the 2x Xeon Gold 6148 CPUs run sustained loads?

Thermal throttling activates once the 24-core processors hit their temperature ceiling, reducing the 2.40GHz clock to protect the LGA3647 sockets.
