Dell PowerEdge R640 8-bay rack server

The Dell PowerEdge R640 is a 1U rackmount server built for business workloads such as file storage, virtualisation, databases, backups and application hosting. It ships with two Intel Xeon Gold 6154 processors running at 3.0 GHz, providing 36 total cores for multi-threaded performance. The system includes 256 GB of DDR4 memory and eight new 1 TB SATA SSDs installed in the front bays. An integrated GPU handles basic display output.

Installation and common issues

The unit arrives with the BIOS configured, controllers set up and storage arrays built by certified technicians, so initial deployment is straightforward. The H730P storage controller simplifies ongoing management of the eight 2.5-inch drive bays. Weight of 60 kg means two-person handling or a lift is required when placing it in a rack. No operating system is included, so an OS must be installed before production use.

Capacity and headroom

With 256 GB of DDR4 memory installed and a maximum capacity of 3 TB, there is significant headroom for additional virtual machines or data-heavy applications. The eight 1 TB SATA SSDs deliver 8 TB of raw storage for operating systems, applications, virtual machines and backups. The dual Xeon Gold 6154 processors support up to two sockets, which are already fully populated, so CPU expansion is not possible beyond this configuration.

Questions about this item

How do I confirm the two Xeon Gold 6154 processors are running at 3.0GHz after setup?

Enter the BIOS or use a hardware monitoring tool; both CPUs should report 20 cores each and a 3.0GHz base clock for a total of 36 cores.

What components are included and which must be purchased separately?

The chassis includes 2× Xeon Gold 6154 CPUs, 256GB DDR4 RAM, 8× 1TB SATA SSDs, H730P controller and X710 network adapter; an operating system is not included.

Which memory capacity should I choose for heavy virtualization?

The system ships with 256GB DDR4 and supports up to 3TB; add DDR4 modules if your workloads need more than the installed amount.
