Four-socket 3U rack server

The Dell PowerEdge R940 is a 3U rack server fitted with four Intel Xeon Gold 5120 processors running at 2.2 GHz with 14 cores each. It ships with 768 GB of DDR4 registered ECC memory across 24 modules and a PERC H730P 2 GB storage controller supporting RAID 0, 1, 5, 6, 10, 50, 60 and pass-through. Eight 300 GB 10 K SAS drives and a quad-port network daughter card with two 1 GbE and two 10 Gb SFP+ links complete the configuration.

Suited to memory-intensive workloads

This system suits databases, virtualisation hosts and analytics platforms that need up to 6 TB of DDR4 across 48 slots and four-socket compute density in 3U. Redundant 1600 W platinum power supplies and iDRAC 9 Enterprise remote management support continuous operation. Buyers who need solid-state storage or more than eight 2.5-inch drive bays should look elsewhere because the supplied chassis is populated with SAS hard drives only.

48 DDR4 slots define maximum capacity

The single specification that decides fit is the 48 DDR4 memory slots, which set the 6 TB ceiling and determine whether your planned memory configuration can be accommodated.

Questions about this item

What comes in the box and what must be bought separately?

The server ships with four Xeon Gold 5120 processors, 768 GB DDR4 ECC memory in 24 modules, a PERC H730P controller with battery, eight 300 GB 10K SAS drives, an X520/I350 quad-port network card, iDRAC9 Enterprise, two 1600 W PSUs, rails and a bezel. No extra parts are included.

Which version should I choose if I need more storage capacity later?

The chassis holds eight 2.5‑inch bays; all are filled with 300 GB drives. To increase capacity you would replace those drives with larger SAS or SATA units supported by the H730P controller.

What does the 2.2 GHz base clock mean once the server is running a real workload?

Each of the 14 cores runs at 2.2 GHz base and can boost to 3.2 GHz under load, giving predictable performance for database and virtualization tasks.
