DELL PowerEdge R940 3U Rack Server 4x Xeon Gold 6142 2.6GHz 16-Core 256GB DDR4 2x 800GB SSD

Mission-critical compute density

The Dell PowerEdge R940 is a 3U rack server built for mission-critical workloads that demand maximum processor density. Four Intel Xeon Gold 6142 processors deliver 64 total cores at a 2.6 GHz base frequency with 3.7 GHz turbo capability. The system ships with 256 GB of DDR4-2666 registered ECC memory across eight 32 GB modules, leaving 40 slots open for expansion up to 6 TB.

Scaling from dual-socket limits

This platform replaces dual-socket servers when thread count, memory capacity or I/O lanes become the bottleneck. The four-socket design removes the need to cluster smaller nodes for in-memory databases, large virtualisation hosts or real-time analytics. The jump is worth it when licensing costs favour fewer sockets or when a single OS image must address the full 6 TB memory ceiling.

Rack-ready integration

The chassis occupies 3U and includes eight 2.5-inch drive bays, currently populated with two 800 GB SATA SSDs behind a PERC H730P controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. Networking is handled by an Intel X520/I350 daughter card providing two 10 Gb SFP+ and two 1 GbE ports. Dual 1600 W platinum power supplies and iDRAC 9 Enterprise enable remote management and redundancy without extra cabling. Rails and a front bezel are included for immediate rack mounting.
