PowerEdge R940 3U 4-Socket Server

The Dell PowerEdge R940 is a 3U rack server built for mission-critical workloads. It ships with four Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores. The system includes 256 GB of DDR4 registered ECC memory across 48 available slots. Dual 1600 W platinum power supplies provide redundancy.

Suited for Dense Compute, Not All-Flash Arrays

This configuration suits organisations that need maximum CPU density and memory capacity in a compact 3U form factor. The eight 600 GB 10K SAS drives and H730P controller support RAID 0, 1, 5, 6, 10, 50 and 60. Buyers who require installed solid-state drives or a larger drive count than the eight 2.5-inch bays provide should evaluate alternative platforms.

48 DDR4 Slots Define Maximum Memory

The server offers 48 DDR4 memory slots with a maximum supported capacity of 6 TB. The installed 256 GB uses eight 32 GB modules at 2400 MHz. This slot count and ceiling are the key figures for planning future memory upgrades.

Questions about this item

How can I verify the four Xeon Gold 5118 processors are running at 2.3 GHz with 12 cores each after setup?

The system BIOS and iDRAC 9 Enterprise will report four sockets populated, each showing a 12-core Xeon Gold 5118 at 2.3 GHz base and 3.2 GHz turbo.

Which drives, controllers, rails and bezel ship with the unit and what must I add?

Included are eight 600 GB 10K SAS drives, the PERC H730P 2 GB controller, Intel X520/I350 quad-port network card, iDRAC 9 Enterprise, two 1600 W PSUs, ready rails and front bezel. No extra parts are required for basic operation.

Should I choose this 256 GB DDR4 configuration or a larger memory option?

This unit ships with 256 GB (eight 32 GB DDR4 2400 MHz RDIMMs) across 48 slots, leaving room to expand toward the 6 TB maximum if workloads demand more capacity.
