PowerEdge R940 3U four-socket server

The Dell PowerEdge R940 is a 3U rack-mount server fitted with four Intel Xeon Platinum 8160 processors running at 2.1 GHz, each providing 24 cores. It ships with 512 GB of DDR4 2666 MHz registered ECC memory installed across 16 modules. The chassis includes eight 2.5-inch SAS/SATA drive trays and a PERC H730P storage controller with 2 GB cache.

Suited for dense virtualisation

This configuration targets organisations that need high core counts and large memory capacity in a compact 3U form factor for database, virtualisation or analytics clusters. Buyers requiring installed solid-state drives, pre-configured RAID arrays or a different processor generation should consider other options.

Four Xeon 8160 CPUs and 512 GB DDR4 decide fit

The decisive specification is the combination of four 24-core Xeon Platinum 8160 processors and 512 GB of DDR4 registered ECC memory, which sets the performance ceiling and memory bandwidth available for the intended workload.

Questions about this item

How deep is the rack and what rail kit do I need for the 3U R940?

The R940 occupies a 3U rack height and ships with Dell Ready Rails for square-hole or threaded-hole racks; verify your cabinet depth before mounting.

In what order should I seat the four Xeon 8160 processors and the 16 DDR4 modules?

Install all four CPUs first, then populate the 48 memory slots following the per-socket channel sequence shown in the service manual; the common error is adding DIMMs before every socket is filled.

When will the PERC H730P battery and the 1600 W power supplies need replacement?

The H730P RAID battery typically lasts three to five years; the hot-swap 1600 W PSUs are rated for continuous operation and should be swapped if a fault LED appears or during scheduled hardware refresh cycles.
