Four-socket Xeon server for dense compute

The Dell PowerEdge R940 fits four Intel Xeon Gold 5120 processors into a 3U rack chassis. Each CPU runs at 2.2 GHz with 14 cores and can reach 3.2 GHz under turbo. The system ships with 512 GB of DDR4 registered ECC memory across 16 modules, leaving 32 slots free for expansion up to 6 TB. It targets organisations that need high thread counts in a compact rack footprint.

Eight enterprise SAS drives and PERC H730P RAID

Eight 2.4 TB 10K SAS drives connect to a Dell PERC H730P controller with 2 GB cache and battery backup. The controller supports RAID levels 0, 1, 5, 6, 10, 50, 60 and pass-through mode, letting you configure redundancy or capacity as required. A quad-port network daughter card adds two 1 GbE and two 10 Gb SFP+ links for storage and cluster traffic. iDRAC 9 Enterprise provides dedicated out-of-band management.

Rails and bezel included; 3U depth needs deep rack

ReadyRails and a front bezel are supplied for standard four-post rack mounting. The 3U height is straightforward, but the chassis depth requires a deep cabinet and adequate airflow planning. Dual 1600 W platinum power supplies are hot-swappable and redundant, so cable routing must allow both units to reach separate PDUs. Memory population follows Dell's optimised sequence; deviating from it can prevent POST.

Questions about this item

When will the PERC H730P controller's 2GB cache battery need replacement?

The H730P uses a battery-backed cache; the battery typically lasts three to five years and should be swapped when iDRAC9 reports a degradation alert.

Which component hits its ceiling first during continuous all-core workloads?

The four Xeon Gold 5120 processors reach their 14-core, 2.2GHz base frequency limit before the 512GB DDR4 memory or the 8x 2.4TB SAS drives saturate.

How loud and hot do the dual 1600W platinum supplies get under 24/7 load?

Redundant 1600W platinum units share the load, keeping fan speeds moderate; iDRAC9 Enterprise monitors inlet temperature and fan RPM in real time.
