Dual-socket Xeon Gold server

The Dell PowerEdge R640 arrives as a 1U rackmount platform with two Intel Xeon Gold 6126 processors running at 2.6GHz. Each CPU provides 12 cores and 19.25MB cache, giving 24 threads for virtualisation, database or compute workloads. The system ships with 64GB of DDR4 ECC registered memory installed and supports expansion up to 7.68TB across its memory slots.

Four 3.5-inch drive bays and PERC H740P

The 4LFF chassis accepts up to four 3.5-inch SATA drives that are not included, letting you choose capacity and redundancy to match the workload. A Dell PERC H740P RAID controller manages the array, while dual 750W power supplies provide redundancy. Remote management is handled by iDRAC9 with an Enterprise licence, and a 10GbE two-port 562T adapter supplies high-speed networking.

No drives or rails included

Storage drives and a rail kit are not installed; both can be added at configuration time. Firmware and BIOS are updated to the latest stable release before shipment, and each unit passes full diagnostics and burn-in testing. The integrated graphics and DDR4 memory configuration mean the platform is ready for headless server roles without additional GPU hardware.

Questions about this item

What limits performance first under sustained load with the two Xeon Gold 6126 processors running at 2.6 GHz?

The 12 cores per CPU and 19.25 MB cache per processor set the compute ceiling; the 64 GB DDR4 ECC registered memory and 7.68 TB maximum capacity define the memory boundary.

How much heat and power should I plan for when the server runs all day with dual 750 W supplies?

Two 750 W power supplies rated for the R720 platform deliver redundant power; the 10 GbE 562T adapter and PERC H740P controller add continuous load, so size cooling for the full supply rating.

Which drive caddies and rails must I already have to populate the four 3.5-inch bays?

The chassis accepts four 3.5-inch SATA drives and uses the PERC H740P RAID controller; you need compatible 3.5-inch drive carriers and a rack rail kit, which is available on request.
