Rack server for virtualization workloads

The Dell PowerEdge R640 is a 1U rackmount server system designed for business applications, virtualization and data-intensive tasks. It ships new with two Intel Xeon Gold 6150 processors providing 36 total cores at 2.70GHz and 128GB of DDR4 ECC Registered memory. Eight 1.2TB 10K RPM SAS drives are installed in the 2.5-inch hot-swap bays.

Suited for compute-heavy services.

This configuration fits organizations running large-scale virtualization, container hosting, ERP or analytics workloads that benefit from high core counts and fast SAS storage. The integrated graphics and lack of discrete GPU support make it unsuitable for buyers who need hardware-accelerated rendering, AI training or visual computing.

Storage controller and drive interface decide

The PERC H740P RAID controller manages the eight 1.2TB SAS drives, so the server is ready for RAID configurations without additional hardware. Buyers requiring a different drive protocol or a controller not listed should verify compatibility before purchase.

Questions about this item

Should I choose the 128 GB DDR4 configuration or add more memory later?

The system ships with 128 GB DDR4 ECC Registered installed and supports up to 3 TB, so you can start with the factory configuration and expand using the remaining DIMM slots when workloads grow.

What does the combined 36 cores and 72 threads at 2.70 GHz mean for my virtualization hosts?

Two Xeon Gold 6150 processors deliver 18 cores each at 2.70 GHz base, giving 36 cores and 72 threads total to schedule heavy VM workloads across the host.

How fast can the dual X540 and dual I350 network ports actually move data?

Dual X540 ports provide 10 GbE connectivity and dual I350 ports provide 1 GbE connectivity for separate management or backup traffic lanes.
