Purpose-built rack server

The Dell PowerEdge R640 is a 1U rackmount server system designed for business workloads such as virtualization, databases, file storage, backups and application hosting. It ships new with two Intel Xeon Gold 6138 processors installed, delivering 40 total cores at 2.00GHz. The system includes 128GB of DDR4 memory and an H730 storage controller. Ten 2.5-inch drive bays provide high-density storage capacity, with eight bays supporting NVMe drives.

Fit for virtualization and mixed workloads

This configuration suits IT teams consolidating multiple virtual machines, running business applications or hosting databases that benefit from high core counts and large memory capacity. The NVMe-capable bays accelerate storage-heavy tasks. Buyers who need GPU acceleration for AI, rendering or high-performance computing should look elsewhere, as only integrated graphics are present. Organisations requiring more than two processor sockets or memory beyond the 3TB maximum will need a different platform.

Ten 2.5-inch bays with eight NVMe slots

The chassis provides ten front-accessible 2.5-inch drive bays, and eight of those bays are NVMe-capable. This layout determines how many high-speed solid-state drives can be installed directly without additional enclosures or adapters. Drive selection is left to the buyer, as no storage drives are included. The H730 controller manages RAID configuration for the installed drives.

Questions about this item

How can I verify the server is operating correctly after initial setup?

Check the front-panel Power, Ethernet and USB LEDs for normal activity and confirm the system BIOS reports both Xeon Gold 6138 processors running at 2.00GHz with 40 total cores and 128GB DDR4 memory.

What components are included and what must be purchased separately?

The chassis, dual Xeon Gold 6138 CPUs, 128GB DDR4 RAM, H730 storage controller and ten 2.5-inch drive trays (eight NVMe-capable) are included; storage drives and an operating system are not supplied.

Which configuration should I choose for virtualization workloads needing fast storage?

Select the 10-bay version with eight NVMe-capable trays to maximise high-speed drive density for virtual machines and databases.
