Four-socket Xeon server with 768 GB DDR4

The Dell PowerEdge R940 is a 3U rack server populated with four Intel Xeon Gold 5120 processors, each running at 2.2 GHz with 14 cores. It ships with 768 GB of DDR4 registered ECC memory across 24 modules and includes a PERC H730P controller managing eight 1.2 TB SAS hard drives. Redundant 1600 W power supplies and iDRAC9 Enterprise remote management are fitted as standard.

Suits heavy multi-threaded workloads.

This server suits environments that need many CPU cores and large memory capacity in a single 3U chassis, such as virtualisation hosts, in-memory databases or ERP platforms. Buyers who require GPU acceleration or high-density flash storage should evaluate alternative platforms because this configuration provides no GPU support and uses SAS hard drives rather than solid-state media.

PERC H730P RAID controller with 2 GB cache

The installed Dell PERC H730P controller offers 2 GB of battery-backed cache and supports RAID levels 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. This specification determines whether the storage topology meets your redundancy and performance requirements before purchase.

Perguntas sobre este artigo

Will the four Xeon Gold 5120 2.2 GHz 14-core processors and 768 GB DDR4 memory work with my existing LGA 3647 platform?

The server uses four Intel Xeon Gold 5120 processors in LGA 3647 sockets with 768 GB DDR4 registered ECC memory across 48 slots, so it matches the same socket and memory generation.

How can I verify the PERC H730P controller and eight 1.2 TB SAS drives are operating correctly after installation?

Use iDRAC 9 Enterprise to check controller firmware, drive health, RAID status and battery condition; the front-panel LCD also shows system posture and any fault LEDs.

What ships with the R940 and which items must I source separately?

The box includes the 3U chassis, four CPUs, 768 GB DDR4, PERC H730P with battery, eight 1.2 TB 10K SAS drives, X520/I350 quad-port network card, iDRAC 9 Enterprise, two 1600 W PSUs, bezel and rails; no extra components are required for basic operation.
