Dell PowerEdge R640 8-Bay SFF Server

The Dell PowerEdge R640 is a 1U rackmount server system designed for business workloads such as virtualization, databases, file storage, and application hosting. It arrives in new condition with dual Intel Xeon Gold 6154 processors and 256GB of DDR4 memory installed. An integrated H730P storage controller manages the eight drive bays populated with new 1TB SATA SSDs.

Suited for virtualization hosts

This configuration suits IT teams building virtualization clusters, database nodes, or consolidated application hosts that need 36 total cores and 256GB of RAM in a single rack unit. Buyers who need GPU acceleration, Fibre Channel connectivity, or more than eight 2.5-inch drive bays should consider other platforms.

Dual Xeon Gold 6154 at 3.0GHz with 36 cores

Two Intel Xeon Gold 6154 CPUs run at 3.0GHz, each providing 14 cores for 36 total threads across the system. The LGA3647 sockets are fully populated, reaching the chassis maximum of two processors. This core count and clock speed define the compute ceiling for the workloads this server can handle.
