Purpose-built density

The Dell PowerEdge R640 packs 40 cores across two Xeon Gold 6254 processors running at 3.10GHz, delivering a dense 1U platform for virtualization, databases and application hosting. It targets IT teams that need high core counts and large memory capacity in a single rack unit without oversized chassis.

Build integration

Ten 2.5-inch bays with eight NVMe-capable slots let you populate fast flash or high-capacity drives while the integrated H730 controller manages RAID and monitoring. The board supports up to 3TB of DDR4, so the installed 512GB can grow as workloads expand, and the two-socket limit keeps licensing and power planning predictable.

Sustained operation

With both Gold 6254 CPUs at their 3.10GHz base clock across all 18 cores per socket, the system maintains throughput for long-running VM fleets and database jobs rather than relying on short turbo bursts. The 60-unit weight and rackmount rails are engineered for continuous duty in dense rows where thermal headroom and service access stay consistent over months.

Preguntas sobre este artículo

How many physical cores does the 2-processor Xeon Gold 6254 configuration deliver for sustained compute?

Each Gold 6254 has 18 cores, so the two installed processors provide 40 cores total for continuous workloads.

What is the typical thermal and acoustic profile when the R640 runs at full load all day?

The 1U chassis uses high-speed system fans to cool the dual 3.10GHz CPUs and 512GB DDR4; expect elevated fan noise and significant heat output under sustained load.

Which storage drives must I supply myself to use the ten 2.5-inch bays?

No drives are included; you must provide 2.5-inch NVMe-capable SSDs or compatible drives for the eight NVMe bays and the two remaining bays.
