Mission-critical compute density

The Dell PowerEdge R940 is a 3U rack server built for organisations running heavy database, virtualisation or analytics workloads. Four Intel Xeon Gold 5118 processors deliver 48 cores at 2.3 GHz with 3.2 GHz turbo, backed by 128 GB of DDR4 registered ECC memory across eight DIMMs.

Four-socket Xeon Gold 5118 configuration

The single specification that determines fit is the four-processor layout: each socket is an LGA 3647 Xeon Gold 5118 with 12 cores, giving a total of 48 cores and a maximum memory ceiling of 6 TB across 48 slots. No further CPU expansion is possible.

Storage and networking integration

Eight 400 GB SATA SSDs connect to the PERC H730P controller with 2 GB cache, supporting RAID 0, 1, 5, 6, 10, 50 and 60. A quad-port daughter card adds two 1 GbE and two 10 Gb SFP+ links, while dual 1600 W platinum power supplies and iDRAC 9 Enterprise provide redundancy and remote management. Ready rails and bezel are included for immediate rack mounting.

Questions about this item

What does the 2.3 GHz base clock mean for real-world throughput on this 48-core server?

The four Xeon Gold 5118 processors each run at 2.3 GHz base with a 3.2 GHz turbo, giving 48 total cores for parallel workloads such as virtualization or database tasks.

How does the PERC H730P controller limit the eight 400 GB SATA SSDs?

The H730P provides 12 Gb/s SAS/SATA connectivity with 2 GB cache and supports RAID 0, 1, 5, 6, 10, 50, 60 plus pass-through, so the SATA SSDs operate at their native 6 Gb/s link speed.

What physical space and mounting hardware does this 3U rack server need?

It occupies 3U of rack height, includes ready rails for square-hole or threaded racks, and ships with a front bezel; redundant 1600 W power supplies are hot-swappable at the rear.
