Four-socket Xeon Gold 5120 server

The Dell PowerEdge R940 is a 3U rack server fitted with four Intel Xeon Gold 5120 processors, each running at 2.2 GHz with 14 cores. It ships with 64 GB of DDR4 ECC memory and two 400 GB SATA SSDs managed by a PERC H730P RAID controller. This configuration targets databases, virtualisation clusters and analytics workloads that demand high core counts in a compact rack footprint.

Check memory slots, drive bays and network needs

The chassis provides 48 DDR4 DIMM slots supporting up to 6 TB, so verify how many additional modules your workload requires before ordering. Eight 2.5‑inch drive bays are available; only two are populated with the included SSDs, leaving room for further SATA or SAS drives. Network connectivity uses a quad‑port daughter card with two 1 GbE and two 10 Gb SFP+ ports — confirm your switch supports SFP+ transceivers.

Dual 1600 W platinum supplies handle peak load

Redundant hot‑swap 1600 W platinum‑efficiency power supplies share the load, keeping each unit well within its efficient range during normal operation. The 3U form factor allows generous airflow across the four CPU heatsinks and the PERC controller battery, so fan speeds remain moderate under typical database or virtualisation loads. Acoustic output is comparable to other enterprise 3U rack servers in a cooled data‑centre aisle.

Questions about this item

What ships inside the server and what must I add myself?

The chassis arrives with four Xeon Gold 5120 processors, 64 GB DDR4 ECC memory, a PERC H730P RAID controller, two 400 GB SATA SSDs, a quad-port X520/I350 network card, iDRAC9 Enterprise, redundant 1600 W power supplies, rails and bezel. All 48 DIMM slots and the remaining six 2.5" drive bays are open for expansion.

Which memory capacity should I select for this R940?

The system includes 64 GB across four 16 GB modules at 2400 MHz. You can add identical DDR4 Registered ECC DIMMs up to the 48-slot, 6 TB maximum.

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

Each 14-core Xeon Gold 5120 runs at 2.2 GHz base and can boost to 3.2 GHz; actual frequency depends on core count, thermal headroom and the specific application mix.
