PowerEdge R940 3U four-socket server

The Dell PowerEdge R940 is a 3U rack-mount server populated with four Intel Xeon Gold 5120 processors, each running at 2.2 GHz with 14 cores. It ships with 64 GB of DDR4 registered ECC memory across 48 slots and a PERC H730P RAID controller with 2 GB cache. Eight 2.4 TB 10K SAS drives fill the 2.5-inch bays, while dual 1600 W platinum power supplies and iDRAC9 Enterprise provide redundancy and remote management.

Suited for dense virtualisation

This configuration fits environments that need high core counts and large memory capacity in a compact 3U form factor. The four-socket design supports up to 6 TB of DDR4 for memory-intensive applications. Organisations requiring GPU compute, all-flash arrays or higher single-thread frequencies should evaluate alternative platforms.

48 DDR4 slots define maximum memory

The server provides 48 DIMM slots populated with 64 GB today and scalable to the platform limit of 6 TB. This slot count is the primary factor when planning memory upgrades or licence modelling for virtualisation density.

Questions about this item

How much power do the dual 1600 Watt platinum supplies draw when the four Xeon Gold 5120 processors run at full load all day?

Each supply is rated at 1600 watts platinum efficiency, and the four 14-core Xeon Gold 5120 CPUs have a base speed of 2.2 GHz with a 3.2 GHz turbo, so sustained full-load draw will approach the combined capacity of the redundant pair.

Which cables and drive trays must I already have to install the eight 2.4 TB SAS drives into the 2.5-inch bays?

The eight 2.4 TB 10K SAS drives ship installed in the eight 2.5-inch hot-swap bays, so no extra trays or cables are required for the factory configuration.

Will the PERC H730P controller recognise older 6 Gb/s SAS drives if I keep some legacy spindles in the array?

The H730P supports 12 Gb/s SAS and SATA with RAID 0, 1, 5, 6, 10, 50 and 60, and it is backward compatible with 6 Gb/s SAS drives, so legacy spindles will be detected and can join the same virtual disks.
