Four-socket Xeon server for dense compute

The Dell PowerEdge R940 fits four Intel Xeon Gold 5118 processors into a 3U rack chassis. Each CPU runs at 2.3 GHz with 12 cores, giving 48 cores total for virtualisation, database or analytics workloads. The system ships with 128 GB of DDR4 registered ECC memory across 48 slots.

Sustained throughput with redundant power

Dual 1600 W platinum power supplies keep all four sockets fed during continuous load. The PERC H730P controller with 2 GB cache manages eight 800 GB SATA SSDs in RAID 0, 1, 5, 6, 10, 50 or 60. Quad-port networking provides two 1 GbE and two 10 Gb SFP+ links for steady data flow.

Verify rack depth and memory expansion plans

The 3U form factor needs a cabinet deep enough for the chassis and ready rails. All 48 DIMM slots are present but only 128 GB is installed; maximum capacity reaches 6 TB with larger modules. No additional drive bays exist beyond the eight 2.5-inch positions.

Questions about this item

How much power do the dual 1600 Watt PSUs draw when all four Xeon Gold 5118 CPUs run at 2.3 GHz under sustained load?

Each supply is rated at 1600 W platinum efficiency; actual draw depends on workload but the redundant pair is sized for full four-socket operation.

Which SFP+ transceivers and cabling must I supply to use the X520 10 GbE ports?

The X520/I350 daughter card provides two 10 Gb SFP+ ports; compatible SFP+ modules and fibre or direct-attach cables are not included.

Can the PERC H730P controller manage the eight installed 800 GB SATA SSDs together with older 2.5" SAS drives I may add later?

The H730P supports mixed SAS and SATA drives across its 12 Gb/s backplane, allowing RAID arrays that combine the existing SSDs with additional SAS units.
