Purpose-built 4-socket server

The Dell PowerEdge R940 is a 3U rack system equipped with four Intel Xeon Platinum 8160 processors, each running at 2.1 GHz with 24 cores. It ships with 768 GB of DDR4 registered ECC memory across 24 slots and includes a PERC H730P controller with battery-backed cache. Two 300 GB 10K SAS drives, a quad-port X520/I350 network daughter card and iDRAC9 Enterprise complete the configuration for organisations running memory-intensive databases or virtualisation clusters.

Installation notes

The chassis supports redundant hot-swap 1600 W power supplies and ships with ready rails and a front bezel for standard rack mounting. Eight 2.5-inch drive bays accept SAS or SATA media through the H730P controller, which offers RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes. Memory population follows Dell’s 48-slot DDR4 layout; mixing registered ECC modules of different speeds will force the system to the lowest common rate, so confirm compatibility before adding DIMMs.

Deciding specification

The server installs the maximum of four processors, leaving no CPU sockets for future expansion. Buyers who anticipate scaling beyond 768 GB of DDR4 memory or adding more than eight 2.5-inch drives should evaluate a platform with additional sockets or larger chassis capacity.

Questions about this item

How can I verify the four Xeon Platinum 8160 processors are all detected after installation?

The system BIOS and iDRAC 9 Enterprise inventory will show four CPUs, each reporting 24 cores at 2.1 GHz with 3.7 GHz turbo capability.

Which components are included and which must be purchased separately?

Included are four Xeon Platinum 8160 CPUs, 768 GB DDR4 ECC memory (24×32 GB), PERC H730P controller, two 300 GB 10K SAS drives, X520/I350 quad-port network card, iDRAC 9 Enterprise, two 1600 W PSUs, rails and bezel. Additional drives or memory are not included.

Should I choose the 768 GB configuration or add more DDR4 modules up to the 6 TB maximum?

The 768 GB (24×32 GB) fills half the 48 DIMM slots; add identical DDR4 2666 MHz registered ECC modules in the remaining slots if your workload needs more than 768 GB.
