40-Core Rack Server for Virtualization

The Dell PowerEdge R640 is a 1U rackmount server built for business workloads such as virtualization, databases, file storage and application hosting. Two Intel Xeon Gold 6138 processors deliver 40 total cores at 2.00GHz for dependable multi-threaded performance. It targets IT teams needing dense compute in a standard rack form factor. Buyers who require GPU acceleration or workstation-class single-thread speed should look elsewhere.

H730 Controller and NVMe Bays

An integrated H730 storage controller simplifies RAID setup and daily management of the internal drive array. The chassis provides ten 2.5-inch bays, eight of which are NVMe capable, allowing high-speed flash configurations without extra adapters. Drives are not included, so you select capacity and endurance ratings that match your workload. Systems needing 3.5-inch drive support or external JBOD connectivity are not addressed by this configuration.

512GB DDR4 with 3TB Headroom

The server ships with 512GB of DDR4 memory installed across two processors, supporting multiple virtual machines and data-heavy applications immediately. Maximum memory capacity reaches 3TB when all DIMM slots are populated, giving ample headroom for future growth. Workloads exceeding 3TB of RAM or requiring persistent memory modules cannot be accommodated by this platform.

Preguntas sobre este artículo

When will the H730 controller or the 10 NVMe-capable 2.5" bays need replacement?

The H730 controller and the 10 NVMe-capable 2.5" bays are built-in components with no user-replaceable schedule; plan to replace individual drives as they age and keep the controller firmware current for compatibility.

What limit appears first when the two Xeon Gold 6138 CPUs run sustained workloads across all 40 cores?

Sustained full-core load on the two Xeon Gold 6138 processors will hit the thermal design envelope first, causing the firmware to throttle clock speeds to stay within the platform power budget.

How much heat and fan noise does the R640 produce when it runs all day with all 10 NVMe bays populated?

With all 10 NVMe bays populated and both Xeon Gold 6138 CPUs active, the R640 exhausts significant heat through its rear fans, which ramp to high RPM under load, producing noticeable datacentre-level noise.
