Dell PowerEdge R640 40-core virtualisation server

This Dell PowerEdge R640 is a 1U rackmount server equipped with two Intel Xeon Gold 6148 processors running at 2.40GHz, delivering 40 cores in total. It ships with 512GB of DDR4 memory and eight new 1TB SATA SSDs managed by an H730P controller. The system is built for business workloads such as virtualisation, databases, file storage and application hosting.

Check CPU socket, memory type

The motherboard uses an LGA3647 socket and supports a maximum of two processors, both already populated. Memory slots accept DDR4 modules up to a total capacity of 3TB; the current 512GB configuration occupies a portion of that headroom. Eight 2.5-inch drive bays are fully occupied by the included SSDs, so additional internal storage requires external enclosures or a chassis change.

Sustained load behaviour with H730P controller

The H730P controller maintains consistent throughput during extended virtualisation and database workloads by leveraging its onboard cache and RAID acceleration. Dual Xeon Gold 6148 CPUs distribute threads across 40 cores, preventing bottlenecks when multiple virtual machines run concurrently. Integrated graphics offloads display tasks, leaving all CPU resources available for compute-intensive services over long periods.

Questions about this item

Does the Dell PowerEdge R640 come with rails or a cable-management arm, or do those need to be ordered separately?

The server ships with the components listed in the configuration — 2× Xeon Gold 6148 processors, 512 GB DDR4, H730P controller and 8× 1 TB SATA SSDs. Rack rails and cable-management arms are not included and must be purchased separately.

Should I choose the 8-bay 2.5" chassis or a larger bay count for this R640?

This unit is the 8-bay 2.5" SFF model. It holds up to eight drives, which are already populated with 1 TB SATA SSDs. If you need more internal bays you would need a different chassis variant.

What does the 40-core total mean for virtual-machine density on this R640?

Two Xeon Gold 6148 CPUs give 40 physical cores at 2.4 GHz. With 512 GB DDR4 and the H730P controller driving eight 1 TB SSDs, the platform can host a high number of concurrent VMs for virtualization, database or backup workloads.
