Four-socket Xeon server for dense compute

The Dell PowerEdge R940 packs four Intel Xeon Platinum 8160 processors, each with 24 cores at 2.1 GHz and a 3.7 GHz turbo, into a 3U rack chassis. It ships with 128 GB of DDR4 registered ECC memory across 48 slots and supports up to 6 TB total capacity. The platform targets organisations running virtualisation clusters, in-memory databases or high-throughput transaction workloads that demand maximum core count in minimal rack space.

Sustained load behaviour with redundant power

Dual 1600 W platinum-efficiency supplies deliver hot-swap redundancy so the system stays online during a unit failure or maintenance swap. The PERC H730P controller with 2 GB cache manages eight 1.2 TB 10K SAS drives in RAID levels 0, 1, 5, 6, 10, 50 or 60, providing consistent throughput for mixed read-write patterns without thermal throttling. Quad-port networking — two 1 GbE and two 10 Gb SFP+ links — keeps storage and migration traffic flowing during extended operations.

Tool-less rails and remote management simplify

ReadyRails slide the 3U chassis into standard square-hole or threaded racks without tools, and the front bezel snaps on afterwards. iDRAC 9 Enterprise gives full out-of-band control — power cycling, BIOS updates, virtual console and hardware health — from any browser, eliminating the need for a crash cart. The only common snag is cable routing: the dense rear I/O panel leaves little room for stiff SAS or fibre leads, so plan cable lengths and latch orientation before racking.

Questions about this item

How much power do the 2x 1600 Watt PSUs draw when the 4× Xeon 8160 2.1 GHz 24-core CPUs run at full load all day?

Each supply is rated at 1600 W with platinum efficiency; actual draw depends on workload but the redundant pair shares the load.

Which rack hardware must I already own to mount the included Ready Rails?

The rails fit a standard 3U rack space; you need a compatible cabinet with square or threaded mounting holes.

Will the PERC H730P controller and 12Gb/s SAS backplane work with my existing 6Gb/s SAS drives?

Yes — the controller supports 12Gb/s SAS and is backward-compatible with 6Gb/s SAS and SATA drives.
