DELL PowerEdge R940 3U Rack Server 4x Xeon Gold 6148 2.4GHz 20-Core 128GB DDR4 8x 800GB SSD H730P

Four-Socket Xeon Gold 6148 Server

The Dell PowerEdge R940 is a 3U rack-mount system built around four Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores. It ships with 128 GB of DDR4 registered ECC memory across 48 slots and eight 800 GB SATA solid-state drives managed by a PERC H730P controller with 2 GB cache. Dual 1600 W platinum power supplies and iDRAC9 Enterprise remote management are included.

Upgrade from Dual-Socket

Moving to four sockets doubles the core count available to heavily threaded workloads such as virtualisation hosts, in-memory databases or high-performance computing clusters. The jump is worth it when licensing costs scale per socket and you need maximum density in a 3U footprint, or when the 6 TB memory ceiling is required for future expansion beyond the installed 128 GB.

Verify Rack Depth, Power and Network Infrastructure

Confirm that your rack can accommodate a 3U chassis with ready rails and that the facility provides redundant feeds for the dual 1600 W supplies. Ensure top-of-rack switches support the installed Intel X520/I350 daughter card with two 10 Gb SFP+ and two 1 GbE ports, and that storage cabling matches the PERC H730P SAS/SATA backplane.
