Mission-critical 4-socket server

The Dell PowerEdge R940 is a 3U rack server built around four Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores and a 3.7 GHz turbo frequency. The system ships with 256 GB of DDR4 2666 MHz registered ECC memory across eight 32 GB modules, leaving 40 of the 48 total slots available for expansion up to 6 TB.

Suited for dense CPU workloads

This platform fits organisations that need maximum core count and memory capacity in a 3U footprint for virtualisation, in-memory databases or high-performance computing. Buyers who require GPU acceleration, a smaller 1U or 2U form factor, or a single-socket design should evaluate other platforms.

Storage controller determines drive support

The included PERC H730P 2 GB controller provides 12 Gb/s SAS and SATA connectivity with RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through, and the chassis holds two 300 GB 10K SAS drives in the eight 2.5-inch bays.

Questions about this item

Will the PERC H730P controller recognise my existing 6 Gb/s SAS drives alongside the installed 12 Gb/s 300 GB disks?

The H730P supports both 6 Gb/s and 12 Gb/s SAS and SATA drives, so your older disks will be detected and can be added to the same RAID arrays.

How do I confirm the four Xeon Gold 6148 CPUs and 256 GB DDR4 are all active after first boot?

Open the iDRAC9 Enterprise web interface or press F2 at POST; the System Overview page lists each of the four 20-core processors and shows 256 GB total memory across the populated slots.

Which items ship in the box and what must I source separately?

The server includes the 3U chassis, four CPUs, 256 GB DDR4, H730P controller, two 300 GB 10K SAS drives, X520/I350 quad-port NIC, iDRAC9 Enterprise, two 1600 W PSUs, bezel and rails; additional drives, SFP+ modules and OS licences are not included.
