Four-Socket Xeon Gold Platform

The Dell PowerEdge R940 is a 3U rack server built around four Intel Xeon Gold 5120 processors, each running at 2.2 GHz with 14 cores. It ships with 128 GB of DDR4 registered ECC memory across eight 16 GB modules. This configuration targets organisations running mission-critical workloads that demand high core counts and large memory capacity in a compact rack footprint.

Build Integration and Expansion

The chassis provides eight 2.5-inch drive bays populated with 300 GB 10K SAS disks and a PERC H730P controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. Forty-eight memory slots remain free for expansion up to 6 TB of DDR4. Redundant 1600 W platinum power supplies and ready rails simplify deployment in standard racks, while the quad-port network daughter card delivers two 1 GbE and two 10 Gb SFP+ connections.

Bundled Management and Connectivity

iDRAC 9 Enterprise enables full remote management including virtual console, power control and hardware monitoring without an operating system. The included front bezel secures the drive bays and the X520/I350 network card adds flexible uplink options for virtualisation or storage traffic. These integrated features reduce the need for separate management appliances or additional network adapters.

Questions about this item

How many processors can the R940 scale to before hitting its socket limit?

The system ships with four Xeon Gold 5120 CPUs and the LGA 3647 platform supports a maximum of four processors, so the socket ceiling is reached immediately.

What is the combined power draw of the redundant supplies when the server runs continuously?

Two 1600 Watt platinum-efficiency PSUs provide full redundancy; each unit can deliver the entire load so sustained operation stays within a single 1600 W envelope.

Which memory specification must the existing DIMMs match for the 48 slots to accept them?

All 48 slots require DDR4 2400 MHz registered ECC modules; the installed 8×16 GB kit follows that exact standard.
