4-Socket 3U Rack Server

The Dell PowerEdge R940 is a 3U rack-mount server system built for dense compute in mission-critical environments. It ships with four Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores and a 3.2 GHz turbo frequency. The system includes 512 GB of DDR4 registered ECC memory across 16 modules and a PERC H730P storage controller with 2 GB cache. Dual 1600 W platinum power supplies provide redundancy.

Suited For Heavy Multi-Threaded Workloads

This configuration targets organisations running large databases, virtualisation clusters or in-memory analytics that benefit from 48 total cores and high memory capacity. The 8-bay 2.5-inch chassis populated with eight 600 GB 10K SAS drives delivers fast rotational storage, while the quad-port network daughter card adds two 1 GbE and two 10 GbE SFP+ connections. Buyers who require GPU acceleration, a smaller form factor or solid-state primary storage should evaluate other platforms.

512 GB DDR4 Registered ECC Memory

The installed memory consists of sixteen 32 GB DDR4 2400 MHz registered ECC DIMMs filling 16 of the 48 available slots. This leaves 32 slots open for expansion up to the 6 TB maximum supported by the Intel C620 chipset. The memory type and registered ECC design are fixed; only DDR4 registered ECC modules are compatible with this platform.

Questions about this item

How do I choose between the four Xeon Gold 5118 processors and the 512GB DDR4 configuration for my workload?

The system ships with four Xeon Gold 5118 CPUs, each running at 2.3GHz with 12 cores, and 512GB of DDR4 2400MHz registered ECC memory installed across 16 DIMM slots, leaving 32 slots free for expansion up to 6TB.

What does the 2.3GHz base clock mean for actual performance once the server is running?

Each Xeon Gold 5118 operates at a 2.3GHz base frequency and can reach 3.2GHz turbo, providing 48 total cores across four sockets for parallel workloads such as virtualization, databases, and compute-intensive applications.

What does the PERC H730P 12Gb/s SAS controller cap in practice for the installed drives?

The PERC H730P controller supports 12Gb/s SAS connectivity for the eight 600GB 10K SAS drives, enabling RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes with 2GB cache and battery backup.
