DELL PowerEdge R640 1U rack server 2x Xeon Gold 6130 2.1GHz 16-core 128GB DDR4 8x 400GB SSD H730P

Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Gold 6130 processors running at 2.1 GHz with 16 cores each and 128 GB of DDR4 registered ECC memory across eight 16 GB modules. The chassis holds eight 2.5-inch drive bays populated with 400 GB SATA SSDs managed by a PERC H730P 2 GB controller. Dual 750 W platinum power supplies, iDRAC9 Enterprise, quad-port networking with two 10 Gb SFP+ and two 1 GbE ports, plus rails and bezel complete the unit.

Suits virtualisation and database clusters.

This configuration suits organisations running virtualisation clusters, in-memory databases or high-throughput storage tiers that benefit from dual-socket density and hardware RAID 0/1/5/6/10/50/60. The 1U form factor and redundant hot-swap power fit standard rack rows where space and uptime are priorities. Buyers who need GPU acceleration or more than eight internal drives should evaluate other platforms because this chassis has no GPU support and the drive bays are fully populated.

24 DDR4 slots with 3 TB maximum capacity

The single specification that decides fit is the memory subsystem: 24 DDR4 DIMM slots supporting up to 3 TB of registered ECC memory. With 128 GB installed across eight slots, sixteen slots remain open for future expansion using compatible DDR4 2666 MHz modules. This headroom lets the server grow with workload demands without requiring a platform change.
