Four-socket Xeon server for heavy workloads

The PowerEdge R940 is a 3U rack server built around four Intel Xeon Gold 5118 processors running at 2.3 GHz with 12 cores each. It ships with 768 GB of DDR4 registered ECC memory across 24 slots, leaving 24 slots free for expansion up to the platform maximum of 6 TB. This configuration targets organisations running large databases, virtualisation clusters or in-memory analytics that need high core counts and memory capacity in a compact rack footprint.

Memory headroom and storage limits

The 768 GB installed provides substantial headroom for most enterprise applications, while the 48 total DIMM slots allow scaling to 6 TB when workloads demand it. Storage is handled by a PERC H730P controller with 2 GB cache supporting RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Two 300 GB 10 K SAS drives are included in the eight 2.5-inch bays, so additional drives are required for capacity-heavy deployments or higher IOPS.

Network and management inclusions

A quad-port network daughter card delivers two 1 GbE and two 10 Gb SFP+ connections for flexible top-of-rack connectivity. iDRAC9 Enterprise enables full out-of-band remote management including virtual console, power control and hardware monitoring. The package also includes redundant 1600 W platinum power supplies, sliding rails and a front bezel for immediate rack installation.

Questions about this item

Will the four Xeon Gold 5118 processors and the H730P controller still recognise my existing DDR4 RDIMMs and SAS drives?

The server has 48 DDR4 slots and a 12 Gb/s SAS controller, so registered ECC DDR4 modules and SAS drives you already own will be detected and used.

How can I verify the 768 GB of memory and the quad-port X520/I350 card are active after installation?

Open iDRAC9 Enterprise or the BIOS; both show the full 768 GB across 24 slots and list the two 1 GbE and two 10 Gb SFP+ ports from the daughter card.

Do the 300 GB SAS drives, rails and bezel ship inside the 3U chassis, or must I order them separately?

Two 300 GB 10K SAS drives, ready rails and the front bezel are included in the box; nothing extra is required for basic operation.
