Four-socket Xeon Gold 5120 platform

The Dell PowerEdge R940 is a 3U rack server populated with four Intel Xeon Gold 5120 processors running at 2.2 GHz, each providing 14 cores. It ships with 768 GB of DDR4 registered ECC memory across 24 modules and a PERC H730P storage controller with battery-backed cache.

Suited for dense compute and memory-heavy workloads

This configuration targets environments that need maximum core count and large memory capacity in a compact 3U form factor. The 8-bay SAS backplane and quad-port 1/10 GbE networking support database, virtualisation and analytics tasks. Buyers who require direct-attached flash tiers or GPU acceleration should look at other platforms because this unit uses SAS drives and has no GPU provision.

PERC H730P RAID controller with 2 GB cache

The installed H730P handles RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode, governing all eight 2.4 TB 10 K SAS drives. Its 12 Gb/s SAS interface and battery-backed write cache determine both data protection and sustained throughput for the storage subsystem.

Questions about this item

What SAS speed does the PERC H730P controller run at with these drives?

The PERC H730P is a 12 Gb/s SAS controller and the eight installed 2.4 TB drives are 12 Gb/s SAS units, so the array operates at 12 Gb/s.

What rack depth clearance do the included Ready Rails need?

The Ready Rails supplied with the R940 are designed for standard 4-post racks and support tool-less mounting in square-hole or round-hole cabinets with a depth range typical for 3U Dell servers.

How are the four Xeon Gold 5120 processors seated, and what is the common mistake?

All four LGA 3647 sockets are populated; the frequent error is not fully engaging each CPU retention lever before locking the heat-sink, which leaves the processor loose and prevents POST.
