Dual Xeon Gold 6150 virtualization server

The Dell PowerEdge R640 is a 1U rackmount server equipped with two Intel Xeon Gold 6150 processors running at 2.70GHz, delivering 36 total cores for compute-intensive workloads. It ships with 64GB of DDR4 ECC registered memory and includes the PERC H740P RAID controller for storage management. This configuration targets businesses running virtualization, databases, file storage, and application hosting in space-constrained environments.

Upgrade from single-socket

Moving to this dual 18-core design adds significant parallel throughput for hypervisors and multi-threaded databases compared to single-processor servers or earlier generation dual-socket systems. The jump is worthwhile when your workloads consistently saturate available threads or when memory capacity per host becomes a bottleneck. The H740P controller also simplifies migration from software RAID or basic hardware controllers.

64GB DDR4 with room to scale to 3TB

The installed 64GB supports multiple virtual machines and data-heavy applications out of the box, while the platform supports up to 3TB of DDR4 ECC registered memory for future growth. Eight 2.5-inch hot-swap drive bays accept your choice of SSDs or HDDs, though drives are not included. Dual 10GbE X540 and dual 1GbE I350 ports handle network traffic for storage replication and client connectivity.

Questions about this item

What rack width and drive-bay size does the R640 require for installation?

The server is a rackmount chassis with eight 2.5-inch hot-swap drive bays included, so it fits standard-width racks and accepts 2.5-inch drives only.

What is the correct order for seating the dual Xeon Gold 6150 CPUs and the H740P controller during setup?

Install both Xeon Gold 6150 processors into the two sockets first, then insert the PERC H740P RAID controller into its dedicated slot before adding memory or drives.

Which memory specification must be matched when expanding the 64 GB DDR4 configuration later?

Add DDR4 ECC registered modules only; the system supports up to 3 TB total capacity across the available DIMM slots.
