Four-socket 3U rack server

The Dell PowerEdge R940 is a 3U rack-mount server equipped with four Intel Xeon Gold 5120 processors, each running at 2.2 GHz with 14 cores. It ships with 256 GB of DDR4 registered ECC memory across eight 32 GB modules. Eight 400 GB SATA SSDs are installed behind the front 2.5-inch drive bays. Dual 1600 W redundant power supplies and iDRAC9 Enterprise remote management are included.

Suits dense virtualisation and in-memory workloads

This configuration targets organisations running heavily threaded applications, large virtual-machine fleets or in-memory databases that benefit from 56 total cores and 256 GB of fast memory. The four-socket design and PERC H730P controller with 2 GB cache support RAID levels 0, 1, 5, 6, 10, 50 and 60. Buyers needing more than 256 GB of RAM or additional drive bays beyond the eight 2.5-inch slots should evaluate larger platforms.

56 cores and 256 GB DDR4 decide fit

The combined 56 processing cores and 256 GB of DDR4 memory are the primary determinants of whether this server matches the workload. The installed H730P controller manages the eight 400 GB SATA SSDs over a 12 Gb/s SAS/SATA interface. Network connectivity provides two 1 GbE and two 10 Gb SFP+ ports via the X520/I350 daughter card.

Perguntas sobre este artigo

What rack height and rails are required to mount this 3U server?

The server occupies 3U of rack height and ships with Ready Rails for direct mounting in a standard enclosure.

How are the four Xeon Gold 5120 processors and 256 GB of DDR4 memory installed, and what step is often missed?

All four processors and 256 GB of DDR4 memory come pre-installed; the step often missed is seating the RAID controller battery on the PERC H730P before powering on.

Which components in this server will need replacement over time?

The PERC H730P RAID controller battery, the 400 GB SATA SSDs, the 1600 W power supplies, and the cooling fans are field-replaceable units that will need replacement over time.
