Purpose-built virtualization server

The Dell PowerEdge R640 is a 1U rackmount server configured with two Intel Xeon Gold 6148 processors running at 2.40GHz. Forty total cores and 128GB of DDR4 memory deliver the parallel throughput required for virtualization clusters, database instances and application hosting. Eight 2.5-inch drive bays populated with 1.2TB 10K SAS disks and an H730P controller provide immediate storage capacity for operating systems, virtual machines and backups.

Fit for multi-tenant workloads, not GPU compute

This platform suits IT teams consolidating workloads onto fewer physical hosts where core count and memory capacity matter more than single-thread speed. The integrated GPU and lack of dedicated accelerator slots make it unsuitable for buyers who need hardware-accelerated graphics, AI inference or high-frequency single-thread performance. Organisations requiring more than two processors or memory beyond 3TB should evaluate larger chassis options.

40 cores across two sockets

The dual-socket LGA3647 design fixes the maximum at two Xeon Gold 6148 CPUs, each contributing 18 cores for a total of 40 logical cores. This hard ceiling on processor count and core density is the primary specification that determines whether the R640 matches a given consolidation ratio or licensing model.

Perguntas sobre este artigo

What does the 40-core total from the two Xeon Gold 6148 CPUs deliver in a live virtualization host?

Forty physical cores at 2.4 GHz give you plenty of threads for running many virtual machines simultaneously, and the 128 GB DDR4 lets you allocate generous memory to each workload.

How does the SAS 12 Gb/s interface on the H730P controller affect the eight 1.2 TB drives?

The controller and drives both operate at 12 Gb/s SAS, so the array can sustain the full 10 K RPM spindle speed without the interface becoming the bottleneck.

What rack depth and rails does the 8-bay 2.5-inch chassis require?

The 1U rackmount body uses standard sliding rails and fits a typical four-post rack with enough depth for the power supplies and rear I/O.
