DELL PowerEdge R640 1U Rack Server 2x Xeon Gold 5118 2.3GHz 12-Core 128GB DDR4 H730P 8x 2.5" Trays

Dual-socket 1U rack platform

The Dell PowerEdge R640 is a dual-socket 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Gold 5118 processors running at 2.3 GHz with 12 cores each and 128 GB of DDR4 registered ECC memory across eight 16 GB modules. The chassis includes eight 2.5-inch SAS/SATA drive trays and a PERC H730P 2 GB RAID controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. Dual 750 W platinum power supplies, iDRAC9 Enterprise, quad-port networking with two 1 GbE and two 10 Gb SFP+ ports, rails and bezel complete the package.

Suited for virtualisation hosts

This configuration suits organisations deploying virtualisation hosts, database nodes or high-performance computing clusters that need two processors and large memory capacity in a single rack unit. The 24 DIMM slots allow expansion up to 3 TB of DDR4, and the PERC H730P handles mixed SAS and SATA drives. Buyers who need more than two processors, a tower chassis, or installed solid-state drives should evaluate other platforms. The server arrives without hard drives, so storage media must be sourced separately.

24 DDR4 slots define maximum memory

The single specification that decides fit is the 24 DDR4 memory slots supporting a maximum of 3 TB. With 128 GB installed across eight slots, sixteen slots remain open for future growth. If the workload demands more than 3 TB of memory or requires a different memory generation, this chassis cannot meet the requirement. All other capabilities scale from this memory ceiling.
