Four-socket 3U rack server

The Dell PowerEdge R940 is a 3U rack-mount system equipped with four Intel Xeon Gold 5120 processors running at 2.2 GHz with 14 cores each. It ships with 128 GB of DDR4 registered ECC memory across 48 DIMM slots and a maximum capacity of 6 TB. Eight 800 GB SATA SSDs are installed behind a PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. Dual 1600 W platinum power supplies provide hot-swap redundancy.

Suited for dense compute and virtualisation

This configuration targets workloads that benefit from high core counts and large memory capacity in a compact 3U form factor, such as database clusters, virtualisation hosts and in-memory analytics. The quad-port network daughter card delivers two 1 GbE and two 10 Gb SFP+ links, while iDRAC9 Enterprise enables full remote management. Organisations requiring GPU acceleration or fibre-channel connectivity will not find those interfaces on this platform.

Storage controller decides RAID flexibility

The PERC H730P controller with 2 GB cache and battery backup determines which RAID levels are available and whether the eight 2.5-inch drive bays can be fully utilised for redundancy or performance. Its 12 Gb/s SAS/SATA interface also governs the maximum throughput of the installed 800 GB SSDs. Buyers should verify that the supported RAID modes match their data-protection requirements before deployment.

Questions about this item

How do I install the Dell PERC H730P controller and what step is often missed?

Seat the H730P in the dedicated internal slot, connect the SAS cables to the backplane, then use the boot-time Ctrl-R utility to create a virtual disk before the OS sees any volume.

Which components will need replacement first in the PowerEdge R940?

The 800GB SATA SSDs and the H730P's 2GB cache battery are the only field-replaceable parts with a finite write or charge life; the 1600W PSUs are hot-swap redundant.

What power limit appears first when all four Xeon Gold 5120 CPUs run at 3.2GHz turbo?

The pair of 1600W platinum supplies set the ceiling; if combined draw exceeds 1600W the system will throttle before either supply trips.
