Purpose-built 1U rack server

The Dell PowerEdge R640 is a 1U rack-mount server designed for data-centre workloads that demand high compute density. It ships with two Intel Xeon Silver 4108 processors running at 1.8 GHz and 64 GB of DDR4 ECC registered memory. The 4LFF chassis supports up to four 3.5-inch SATA drives via a PERC H740P RAID controller. Remote management is handled by iDRAC9 with an Enterprise licence.

Suited for virtualisation hosts and database nodes

This configuration fits organisations building virtualisation clusters, database servers or high-throughput storage arrays where CPU core count and memory capacity matter. The dual-processor layout and large maximum memory ceiling of 7.68 TB provide headroom for growth. Buyers who require GPU acceleration, additional PCIe expansion slots or 2.5-inch drive bays should evaluate alternative chassis designs.

Four 3.5-inch drive bays with PERC H740P RAID

The single specification that determines fit is the 4LFF drive bay count paired with the PERC H740P controller. It defines how many large-capacity SATA drives you can install and the RAID levels available. Confirm that four bays satisfy your storage layout before purchase.

Perguntas sobre este artigo

How do I confirm the R640 is operating correctly after initial power-on?

Watch the iDRAC9 Enterprise dashboard for green health LEDs on both Xeon Silver 4108 CPUs, the 64GB DDR4 ECC memory and the PERC H740P controller, then run the built-in diagnostics from the lifecycle controller.

Which components ship with the 4LFF chassis and what must I source myself?

The box contains the R640 4x3.5" chassis, 2x Xeon Silver 4108 processors, 64GB DDR4 ECC registered RAM, PERC H740P RAID controller, 10GbE 2-port 562T adapter, 2x 750W power supplies and rails on request; 3.5" SATA drives are not included.

Should I choose the 64GB DDR4 configuration or expand toward the 7.68TB maximum?

Start with the installed 64GB DDR4 ECC registered memory for typical virtualization workloads; add more DDR4 modules later only if your application monitoring shows sustained memory pressure.
