PowerEdge R640 dual-socket 1U server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre workloads. Two Intel Xeon Silver 4116 processors deliver 24 cores at 2.1 GHz with 3.0 GHz turbo. 256 GB of DDR4-2400 registered ECC memory occupies eight of 24 DIMM slots. Eight 2.4 TB 10K SAS drives sit behind a PERC H730P controller with 2 GB cache and battery-backed write-back.

Compatibility checklist before ordering

Verify the rack provides 1U spacing and supports the included Ready Rails kit. Confirm the facility can supply redundant power to the two 750 W platinum-efficiency hot-swap PSUs. Ensure network uplinks match the X520/I350 daughter card with two 1 GbE and two 10 Gb SFP+ ports. Plan operating-system licences for 24 logical cores and storage layout across eight 2.5-inch bays.

Bundled accessories and their impact

Ready Rails simplify installation in standard four-post racks without tools. The front bezel adds physical security and consistent airflow alignment. iDRAC 9 Enterprise enables full out-of-band remote management, virtual console and automated lifecycle updates. The H730P battery protects cached writes during power loss, preserving array integrity across RAID 0, 1, 5, 6, 10, 50 and 60 configurations.
