Quad-socket Xeon Gold 6148 platform

The Dell PowerEdge R940 is a 3U rack server populated with four Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores. It ships with 512 GB of DDR4 registered ECC memory across 16 modules and includes eight 600 GB 10K SAS drives managed by a PERC H730P controller with 2 GB cache.

Redundant power and remote management

Dual 1600 W platinum power supplies provide hot-swap redundancy for continuous operation. The iDRAC 9 Enterprise module enables full out-of-band management, while a quad-port network daughter card delivers two 1 GbE and two 10 Gb SFP+ connections. Rails and a front bezel are included for immediate rack installation.

Suits dense virtualization and database workloads

This configuration targets organisations consolidating heavy virtualization, in-memory databases or real-time analytics into a single 3U chassis. Buyers who need more than 48 memory slots, additional drive bays beyond the eight 2.5-inch bays, or GPU-accelerated compute should evaluate alternative platforms.
