Four-socket Xeon Gold server for dense compute

The Dell PowerEdge R940 packs four Intel Xeon Gold 6148 processors, each with 20 cores at 2.4 GHz and a 3.7 GHz turbo, into a 3U rack chassis. It targets organisations running virtualisation clusters, in-memory databases or high-throughput analytics that need maximum core count per rack unit.

64 GB DDR4 now, 6 TB ceiling later

The system ships with 64 GB of DDR4 2666 MHz registered ECC memory across four modules, leaving 44 of the 48 DIMM slots free for expansion. The C620 chipset supports up to 6 TB, so memory-heavy workloads can scale without replacing the platform.

PERC H730P, quad-port networking.

A PERC H730P 2 GB controller drives eight 2.5-inch SAS/SATA trays with RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through. An Intel X520/I350 daughter card adds two 1 GbE and two 10 Gb SFP+ ports, while iDRAC9 Enterprise handles remote management. Dual hot-swap 1600 W platinum supplies and included rails complete the build.

Questions about this item

Will my existing DDR4 2666MHz registered ECC modules work alongside the 64GB already installed?

Yes, the system has 48 DDR4 slots and supports up to 6TB total, so your compatible registered ECC modules can be added to the four 16GB sticks already present.

How can I confirm the PERC H730P controller and both 1600W power supplies are operating correctly after installation?

Use iDRAC9 Enterprise to check controller health, battery status, and power-supply redundancy alerts; the front-panel LCD will also show green status when all components report normal.

Which drive trays and rails are included, and what must I purchase separately to populate the storage bays?

The server ships with eight 2.5" SAS/SATA hot-swap trays and ready rails; you must supply your own 2.5" SAS or SATA hard drives or SSDs to fill the bays.
