Four-socket 3U server with 768GB DDR4

The Dell PowerEdge R940 is a 3U rack server populated with four Intel Xeon Gold 5120 processors running at 2.2GHz with 14 cores each. It ships with 768GB of DDR4 2400MHz registered ECC memory across 24 modules and a PERC H730P 2GB storage controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. Two 800GB SATA SSDs are installed in the 8-bay 2.5-inch chassis and dual 1600W platinum power supplies provide redundancy.

Suited for high-core virtualisation.

This configuration targets organisations that need maximum core count and memory capacity in a 3U footprint for virtualisation, in-memory databases or ERP systems. Buyers who require higher single-thread frequency or GPU acceleration should evaluate alternative platforms. The quad-port network daughter card delivers two 1GbE and two 10Gb SFP+ connections and iDRAC9 Enterprise enables full remote management.

48 DDR4 slots support up to 6TB

The system provides 48 DDR4 memory slots with a maximum capacity of 6TB, allowing significant expansion beyond the factory-installed 768GB. The LGA 3647 socket and Intel C620 chipset support the four installed Xeon Gold 5120 CPUs at the platform maximum of four processors.

Questions about this item

How can I confirm the PERC H730P controller is managing the two 800GB SSDs in RAID after installation?

Open the controller BIOS or iDRAC9 Enterprise storage view; both 800GB SATA SSDs should appear as a single virtual disk with the chosen RAID level and a healthy status.

Which items ship with the server and which parts must be sourced separately?

Included: 4x Xeon Gold 5120 processors, 768GB DDR4 (24x 32GB modules), H730P controller, 2x 800GB SATA SSDs, X520/I350 quad-port NIC, iDRAC9 Enterprise, 2x 1600W PSUs, bezel and rails. No additional drives or memory are required for the listed configuration.

The spec shows 48 memory slots and 768GB installed — how do I decide whether to populate the remaining slots?

The 768GB ships as 24x 32GB DDR4 modules, leaving 24 free slots. Add matching 32GB DDR4 registered ECC DIMMs in matched sets per CPU socket if your workload needs more than 768GB up to the 6TB maximum.
