Quad-socket Xeon server for mission-critical

The PowerEdge R940 fits four Intel Xeon Gold 5120 processors, each with 14 cores at 2.2 GHz and a 3.2 GHz turbo frequency. The system ships with 128 GB of DDR4 registered ECC memory across 48 slots, supporting up to 6 TB total capacity. It targets databases, virtualization clusters and real-time analytics that demand high core counts in a 3U rack footprint.

Dual 1600 W platinum supplies

Redundant 1600 W platinum-efficiency power supplies share the load and allow replacement without downtime. The 3U chassis uses forced-air cooling designed for the installed CPU and drive configuration. Acoustic output and exact power draw vary with workload but remain within enterprise rack specifications.

H730P RAID controller

A Dell PERC H730P 2 GB controller manages the eight 1.2 TB 10 K SAS drives with RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes. An Intel X520/I350 daughter card adds two 1 GbE and two 10 Gb SFP+ ports. iDRAC 9 Enterprise provides remote management, while ready rails and a front bezel simplify rack installation.

Questions about this item

How do I install the 48 DDR4 memory modules and what step is often missed?

Populate all 48 slots evenly across the four CPU sockets so each Xeon Gold 5120 has balanced channels; the step often missed is skipping the registered ECC requirement, which prevents the server from posting.

Which component will need replacement first under continuous operation?

The eight 1.2 TB 10K SAS drives have moving parts and a finite write endurance, so they are the first items likely to require replacement during sustained use.

What thermal or power limit appears first when all four 14-core Xeons run at 3.2 GHz turbo?

The dual 1600 W platinum power supplies set the ceiling; if combined draw exceeds their rating, the system throttles before any temperature limit is reached.
