Mission-critical 4-socket 3U rack server

The Dell PowerEdge R940 is a 3U rack server built for mission-critical workloads. It carries four Intel Xeon Platinum 8160 processors, each running at 2.1 GHz with 24 cores. The system ships with 256 GB of DDR4 2666 MHz registered ECC memory across eight 32 GB modules. Dual 1600 W platinum power supplies and iDRAC 9 Enterprise provide redundant power and remote management out of the box.

Buyers needing maximum core density in 3U.

This server suits organisations that need the highest core count and memory capacity available in a 3U form factor. Virtualisation hosts, large in-memory databases and real-time analytics clusters will use the four-socket design and 48 DIMM slots. Buyers running lighter workloads, single-threaded applications or workloads that fit in a 1U or 2U chassis should consider a smaller platform instead.

48 DIMM slots and 6 TB maximum memory decide fit

The board provides 48 DDR4 DIMM slots with a 6 TB maximum capacity, so the memory ceiling is the specification that determines whether this chassis matches the workload. Eight 32 GB modules are installed today, leaving 40 slots open for future expansion. The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 across the eight 2.5-inch SAS/SATA drive bays.

Questions about this item

How many memory slots remain free after the 256GB DDR4 is installed?

Eight 32GB modules fill 8 of the 48 DDR4 slots, leaving 40 slots available for expansion up to the 6TB maximum.

What is the typical power draw of the two 1600W platinum supplies under full load?

Each supply is rated at 1600 watts platinum efficiency; the redundant pair shares the load so neither unit runs at its limit during sustained operation.

Which drive trays and backplane interfaces are populated in the 8-bay front?

The server ships with eight 2.5-inch SAS/SATA trays and no drives installed; the backplane connects to the PERC H730P controller for RAID 0, 1, 5, 6, 10, 50, 60 or pass-through.
