Four-socket Xeon Platinum 8160 server for heavy

The PowerEdge R940 is a 3U rack server built around four Intel Xeon Platinum 8160 processors running at 2.1GHz with 24 cores each. It ships with 768GB of DDR4 registered ECC memory across 24 slots and a PERC H730P controller driving two 400GB SATA SSDs. Redundant 1600W power supplies and iDRAC9 Enterprise remote management are included.

Suits dense compute needs.

This system fits teams that need maximum processor density and memory capacity in a standard 3U form factor. Quad-socket scaling supports heavy virtualization, in-memory databases, and parallel workloads. Buyers who need only one or two processors should look at smaller platforms.

48 DDR4 slots and four LGA 3647 sockets

The board provides 48 memory slots with a 6TB maximum capacity, populated here with 24 modules of 32GB DDR4-2666. Four LGA 3647 sockets are fully occupied by the Platinum 8160 CPUs, so no further processor upgrades are possible. The H730P controller handles RAID 0, 1, 5, 6, 10, 50, and 60 across the eight 2.5-inch drive bays.

Questions about this item

How loud and hot does the R940 run with its dual 1600 W power supplies under continuous load?

The server ships with redundant 1600 W platinum-efficiency power supplies designed for hot-swap operation, keeping power delivery stable during all-day workloads.

Which cabling and drives must I already have to use the PERC H730P controller and the eight 2.5-inch bays?

The H730P supports SAS and SATA drives; the two installed 400 GB SSDs use SATA, so additional 2.5-inch SAS or SATA drives and matching cables are required to fill the remaining bays.

Will the quad-port X520/I350 network card with two 1 GbE and two 10 Gb SFP+ ports work with my existing copper switches?

The 1 GbE ports connect directly to standard copper switches; the 10 Gb SFP+ ports require compatible SFP+ transceivers and fibre or direct-attach cables to link to older 10 GbE infrastructure.
