Mission-critical compute density

The Dell PowerEdge R940 is a 3U rack server built for organisations that run large databases, virtualisation clusters or in-memory analytics. Four Intel Xeon Gold 5118 processors deliver 48 cores at 2.3 GHz with 3.2 GHz turbo, while 512 GB of registered ECC DDR4 across 16 slots provides the memory bandwidth those workloads demand. Redundant 1600 W platinum power supplies and iDRAC 9 Enterprise keep the platform available for continuous operation.

Scaling from dual-socket limits

Teams that have maxed out two-socket servers and still need more threads or memory capacity will see an immediate jump by moving to this four-socket design. The Intel C620 chipset supports up to 6 TB of DDR4 across 48 slots, so the installed 512 GB can grow without a platform change. The PERC H730P controller adds hardware RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through, letting you migrate existing SAS or SATA arrays without reconfiguration.

Rack integration and common pitfalls

The unit ships with ready rails and a front bezel, so it mounts in a standard 3U space without extra hardware. Eight 2.5-inch SAS/SATA trays are populated but empty; you must supply compatible drives and cable them to the H730P backplane. The X520/I350 daughter card provides two 1 GbE and two 10 Gb SFP+ ports — verify your switch optics match SFP+ before deployment. iDRAC 9 Enterprise requires a dedicated management network and valid licence for full remote console and lifecycle features.

Questions about this item

What rack depth and rail type are required to mount the 3U PowerEdge R940?

The server occupies 3U of rack height and ships with Ready Rails for square-hole or round-hole racks; verify your cabinet depth accommodates the full chassis length.

How are the four Xeon Gold 5118 processors and 512GB DDR4 memory installed, and what step is often missed?

All four LGA 3647 sockets are already populated with the 12-core 2.3GHz CPUs and the 48 DIMM slots hold 16×32GB registered ECC modules; the common oversight is not enabling the memory training sequence on first boot.

Which components will need replacement first in the PowerEdge R940?

The H730P controller battery, the two 1600W hot-swap power supplies, and the cooling fans are the primary field-replaceable units; drive trays accept 2.5" SATA or SAS media for future storage swaps.
