DELL PowerEdge R940 3U rack server 4x Xeon Gold 6130 2.1GHz 16-core 256GB DDR4 8x 800GB SSD

3U 4-Socket Xeon Server

The Dell PowerEdge R940 is a 3U rack-mount server system built around four Intel Xeon Gold 6130 processors. Each CPU runs at 2.1 GHz with 16 cores and a 3.7 GHz turbo frequency. The system ships with 256 GB of DDR4 2666 MHz registered ECC memory across 48 slots and a Dell PERC H730P RAID controller with 2 GB cache.

Suits dense compute and memory workloads

This configuration suits organisations running virtualisation, in-memory databases or high-thread-count applications that benefit from 64 total cores and a 6 TB maximum memory ceiling. The eight 800 GB SATA SSDs and quad-port 1 GbE plus 10 GbE SFP+ networking support storage-heavy and network-intensive tasks. Buyers who require GPU acceleration, a 1U or 2U chassis, or more than eight drive bays should evaluate other platforms.

Four-socket 3U limit defines scaling ceiling

The R940 reaches its maximum processor count at four sockets in a 3U height, fixing the upper bound for CPU licensing and memory capacity at 6 TB. With 48 DIMM slots already populated to 256 GB, further memory expansion stays within the same chassis. This constraint makes the server a fit-for-purpose choice when the workload fits the four-socket envelope and a larger form factor is not justified.
