Dense dual-socket 1U platform

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Gold 6134 processors running at 3.2 GHz with 3.7 GHz turbo across eight cores each. Memory is 128 GB of DDR4 2666 MHz registered ECC in eight 16 GB modules. Eight 600 GB 10K SAS 2.5-inch drives are managed by a PERC H730P controller with 2 GB cache.

SAS 12 Gb/s controller and 10 Gb SFP+ networking

Storage connects through a Dell PERC H730P 2 GB controller that supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through at 12 Gb/s SAS/SATA speeds. The installed drives are 10K SAS units; no SSDs are present. Networking is provided by an Intel X520/I350 daughter card delivering two 1 GbE ports and two 10 Gb SFP+ ports. iDRAC 9 Enterprise handles remote management.

Verify rack space, power and memory headroom

The chassis occupies 1U and includes ready rails and a front bezel; confirm your rack depth and rail compatibility before ordering. Dual 750 W platinum hot-swap power supplies provide redundancy; ensure your PDU connectors match. The system has 24 DDR4 slots with a 3 TB maximum, so 16 slots remain open for future expansion.
