Dell PowerEdge R640 10SFF 40-Core Server

The Dell PowerEdge R640 is a 1U rackmount server built for virtualization, databases, and application hosting. It ships with two Intel Xeon Gold 6138 processors delivering 40 cores total at 2.00GHz. The system includes 64GB of DDR4 memory and an H730P storage controller. Ten 2.5-inch drive bays support up to eight NVMe drives for high-speed storage.

Suited for dense virtualization and data workloads

This server fits environments that need maximum compute density in a single rack unit with flexible NVMe storage options. The dual-socket design and 3TB maximum memory capacity support heavy multi-VM deployments. Buyers who require GPU acceleration or larger 3.5-inch drive bays should evaluate alternative platforms. The unit arrives without an operating system or drives installed.

10-bay 2.5-inch chassis with 8 NVMe slots

The front panel provides ten hot-swap bays, eight of which are NVMe-capable, connected through the integrated H730P RAID controller. This layout determines how many high-performance drives can be added without extra cabling or backplanes. Storage capacity and drive type remain entirely configurable at deployment. Network connectivity uses onboard X540 and I350 controllers.

Questions about this item

Will the H730P RAID controller or the NVMe drives I add need replacement later?

The H730P controller manages the 10 drive bays; NVMe drives you install are consumable media that will eventually wear out and require replacement.

What limits sustained performance first — the 2.00 GHz Xeon Gold 6138 CPUs or the 64 GB DDR4 memory?

With only 64 GB fitted against a 3 TB maximum, memory capacity is the practical ceiling for virtualization density long before the 40 cores saturate.

How loud and hot does the 1U chassis run when all 40 cores and 10 drive bays are active all day?

The 1U rackmount form factor uses high-speed fans to cool two Xeon Gold 6138 CPUs and ten 2.5" drives, so expect noticeable airflow noise and steady heat output under continuous load.
