Dell PowerEdge R640 40-Core Server

The Dell PowerEdge R640 is a 1U rackmount server system built for business workloads such as virtualization, databases, file storage, backups and application hosting. It runs on two Intel Xeon Gold 6148 processors, each with 24 cores at 2.40GHz, delivering 40 total cores across dual sockets. The system includes 384GB of DDR4 memory and a PERC H730P storage controller.

Suited for virtualization

This server suits IT teams consolidating multiple virtual machines, databases or business applications onto a single dense platform with high core count and large memory. Buyers needing GPU acceleration, fibre-channel connectivity, or more than two processor sockets should evaluate alternative platforms. The integrated graphics and ten 2.5-inch bays limit specialised compute or massive local storage expansion.

Dual Xeon Gold 6148 24-core CPUs decide fit

The two Gold 6148 processors provide 48 physical cores combined, setting the ceiling for concurrent threads and licensing costs in virtualised environments. Memory scales to 3TB across DDR4 slots when workloads grow beyond the installed 384GB. The LGA3647 socket and H730P controller define compatible upgrades for storage and processing.

Questions about this item

Should I choose the 10-bay 2.5-inch chassis or a different drive-count version?

This unit ships with the 10-bay 2.5-inch chassis and ten new 2TB SATA SSDs already installed, so no other drive-count version applies to this listing.

What does the 40-core figure mean once the server is running workloads?

Two Xeon Gold 6148 processors give 40 total cores at 2.40GHz, providing the thread count needed for heavy virtualization, database and application hosting tasks.

How does the H730P controller cap storage performance with these SATA SSDs?

The H730P manages the ten SATA SSDs over 6Gb/s SATA links, so sustained throughput is limited by the SATA interface rather than the controller's PCIe bandwidth.
