Dell PowerEdge R640 4LFF dual Xeon server

The Dell PowerEdge R640 is a 1U rack server equipped with two Intel Xeon Silver 4108 processors running at 1.8 GHz and 128 GB of DDR4 ECC registered memory. It includes a PERC H740P RAID controller and a 10 GbE two-port 562T network adapter. The chassis supports up to four 3.5-inch SATA drive bays and ships without any installed drives.

Suited for virtualisation hosts

This configuration fits organisations that need dense compute and large memory capacity in a single rack unit. Buyers who require more than four drive bays, GPU acceleration or a different drive interface should evaluate alternative chassis designs. The integrated graphics and single remote-management controller limit use cases that demand discrete GPU compute or redundant management paths.

Four 3.5-inch SATA bays with PERC H740P RAID

The storage subsystem centres on the PERC H740P controller managing up to four 3.5-inch SATA drives. No drives are installed, so the buyer must supply compatible SATA media. Maximum system memory reaches 7.68 TB across the DDR4 slots.

Questions about this item

How much heat and power do the dual 1.8GHz Xeon Silver 4108 CPUs and 128GB DDR4 produce under continuous load?

Two Xeon Silver 4108 processors at 1.8GHz and 128GB DDR4 draw significant power and generate heat that requires the dual 750W supplies and front-to-rear airflow; exact watts depend on workload and installed drives.

Which drive type and caddy do I need to populate the four 3.5" bays behind the PERC H740P controller?

The chassis accepts four 3.5-inch SATA drives or SSDs; each bay uses a Dell hot-plug caddy that mates with the backplane connected to the PERC H740P RAID controller.

Will the integrated graphics and iDRAC9 Enterprise work with my existing KVM switch and monitoring tools?

Integrated graphics provides basic VGA output for local KVM access, while iDRAC9 Enterprise offers a dedicated network port for remote console, virtual media and hardware monitoring independent of the operating system.
