DELL PowerEdge R940 3U rack server 4× Xeon Gold 6142 2.6GHz 16-core 512GB DDR4 8× 400GB SSD H730P

Quad-socket 3U server for mission-critical workloads

The Dell PowerEdge R940 is a 3U rack server equipped with four Intel Xeon Gold 6142 processors running at 2.6 GHz with 16 cores each. It ships with 512 GB of DDR4 2666 MHz registered ECC memory across 16 modules and eight 400 GB SATA SSDs managed by a PERC H730P RAID controller with 2 GB cache. Dual 1600 W platinum power supplies, iDRAC9 Enterprise, quad-port networking and rails are included.

Suited for dense compute, not GPU-heavy builds

This platform suits organisations that need maximum core density and memory capacity in a 3U form factor with redundant 1600 W power supplies. Buyers who require GPU acceleration or more than eight drive bays should evaluate alternative chassis designs. The four-socket limit and 3U height define the expansion ceiling for this configuration.

6 TB DDR4 ceiling decides memory growth

The Intel C620 chipset supports up to 6 TB of DDR4 across 48 DIMM slots, so the installed 512 GB leaves substantial headroom for in-memory databases or virtualisation. Verify that your application licences and OS edition can address the full capacity before populating the remaining slots.
