Four-socket Xeon Gold 6142 server

The Dell PowerEdge R940 is a 3U rack server fitted with four Intel Xeon Gold 6142 processors running at 2.6 GHz with a 3.7 GHz turbo frequency. Each CPU provides 16 cores, giving 64 cores in total. The system includes 768 GB of DDR4 2666 MHz registered ECC memory across 24 slots and a PERC H730P 2 GB storage controller supporting RAID 0, 1, 5, 6, 10, 50, 60 and pass-through.

Suits dense compute workloads.

This server targets organisations that run memory-intensive databases, virtualisation clusters or real-time analytics and require four-socket scaling in a 3U form factor. It provides an Intel X520/I350 quad-port network daughter card with two 1 GbE and two 10 Gb SFP+ connections and iDRAC 9 Enterprise for remote management. Buyers who only need a single processor or fewer memory slots should consider smaller platforms.

768 GB DDR4 in 24 DIMMs decides fit

The installed memory uses 24 modules of 32 GB DDR4 registered ECC, leaving 24 of the 48 total slots free for expansion up to the 6 TB maximum. The chassis holds eight 2.5-inch SAS/SATA drive trays without drives, and power comes from redundant 1600 W platinum-efficiency supplies. Confirm that your workload fits the LGA 3647 socket and C620 chipset before ordering.

Questions about this item

Will my existing SAS drives connect directly to the 2.5" trays and the H730P controller?

The server includes eight 2.5" SAS/SATA trays and a PERC H730P 12Gb/s SAS/SATA controller, so standard SAS or SATA drives fit the bays and are supported by the RAID controller.

How do I confirm all four Xeon Gold 6142 processors and the 768GB DDR4 are recognised at boot?

During POST the BIOS will list each of the four 16-core Xeon Gold 6142 CPUs and show the full 768GB of DDR4 2666MHz registered ECC memory; iDRAC9 Enterprise also reports the complete inventory remotely.

Which items ship with the unit and which must I purchase separately?

The box contains the 3U chassis with 4x Xeon Gold 6142 CPUs, 768GB DDR4, H730P controller, 8x 2.5" trays, X520/I350 quad-port NIC, iDRAC9 Enterprise, 2x 1600W PSUs, rails and bezel; no hard drives or SSDs are included.
