Dell PowerEdge R640 40-Core Server

The Dell PowerEdge R640 is a 1U rackmount server system 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, delivering 40 cores in total and 128 GB of DDR4 memory installed. The chassis provides ten 2.5-inch drive bays, eight of which are NVMe capable, and includes an H730P storage controller. No operating system or drives are included.

Suited for virtualization

This configuration suits IT teams consolidating multiple virtual machines, hosting business applications or running database workloads that benefit from high core counts and large memory headroom. The maximum memory capacity of 3 TB allows significant future expansion. Buyers who need GPU acceleration for compute-intensive tasks should look elsewhere, as only integrated graphics are present. Organisations requiring pre-installed drives or an operating system will need to source those separately.

128 GB DDR4 with room to grow

The installed 128 GB DDR4 comfortably handles dozens of virtual machines, container clusters and memory-heavy databases. With a 3 TB ceiling across the available slots, headroom remains generous for future scaling. Storage performance scales with the chosen drives; the ten 2.5-inch bays and H730P controller support mixed SSD and HDD configurations. The system reaches its compute limit at the dual-socket maximum of 40 cores, so workloads demanding higher thread counts will require a different platform.
