8-bay 2.5-inch rack server

The Dell PowerEdge R640 is a 1U rackmount server system built for business workloads such as virtualization, databases and application hosting. Two Intel Xeon Gold 6154 processors deliver 36 total cores at 3.0GHz, supported by 256GB of DDR4 memory. Eight new 1TB SATA SSDs and an H730P storage controller provide ready-to-use capacity for operating systems, virtual machines and backups.

Suits dense virtualization; not for GPU compute

This configuration suits organisations that need high core counts and large memory in a compact form factor for hypervisor clusters or database instances. Buyers who require dedicated GPU acceleration for AI training, rendering or high-performance computing should look at a different platform. The integrated graphics only cover basic display output and management tasks.

Dual 22-core Xeon Gold 6154 CPUs

The decisive specification is the pair of Xeon Gold 6154 processors, each with 22 cores running at 3.0GHz, giving 36 usable cores in total. This core density determines how many virtual machines or container workloads the server can run concurrently. Memory can be expanded to 3TB DDR4 if workloads grow beyond the installed 256GB.

Questions about this item

What rack depth and rail kit does the R640 8x2.5" chassis require for mounting?

The R640 is a 1U rackmount server; use Dell sliding rails matched to your rack depth and leave space at the rear for cable bend radius and airflow.

Which BIOS and controller steps must be completed before the H730P array is built?

Technicians set up the BIOS, configure the H730P controller, then build the RAID array before installing any operating system.

What memory type and maximum capacity should I plan for when the 256 GB DDR4 needs expanding?

The system uses DDR4 memory and supports up to 3 TB total across its DIMM slots.
