Dense 1U dual-socket platform

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out computing. It carries two Intel Xeon Gold 6142 processors, each with 16 cores running at 2.6 GHz. The system ships with 128 GB of DDR4 registered ECC memory across 24 slots. This configuration targets virtualisation clusters, database nodes and high-performance workloads that demand maximum throughput per rack unit.

24 DDR4 slots and 3 TB memory ceiling

The motherboard provides 24 DIMM slots supporting up to 3 TB of DDR4 memory. Eight slots are populated with 16 GB modules at 2666 MHz, leaving 16 slots free for expansion. This capacity headroom lets operators scale memory independently of compute, matching licence costs or dataset growth without replacing the chassis.

PERC H730P RAID and quad-port networking

Storage is handled by a PERC H730P controller with 2 GB cache, supporting RAID 0, 1, 5, 6, 10, 50 and 60 across eight 2.5-inch SATA bays. Two 800 GB SATA SSDs are installed. Networking uses an Intel X520/I350 daughter card delivering two 1 GbE and two 10 Gb SFP+ ports. Dual 750 W platinum power supplies and iDRAC9 Enterprise remote management complete the infrastructure-ready package.

Questions about this item

What does the 2.6 GHz base clock mean when both Xeon Gold 6142 processors are installed?

The server runs with two 16-core Xeon Gold 6142 CPUs at 2.6 GHz base frequency, reaching up to 3.7 GHz turbo when thermal headroom allows.

How does the PERC H730P controller limit the installed SATA SSDs?

The H730P provides 12 Gb/s SAS/SATA connectivity with 2 GB cache, supporting RAID 0, 1, 5, 6, 10, 50, 60 and pass-through for the two 800 GB SATA SSDs.

What rack space and rails are needed to mount this 1U server?

The chassis occupies 1U of rack height and ships with Dell Ready Rails for tool-less installation in standard 4-post racks.
