DELL PowerEdge R940 3U Rack Server 4x Xeon Gold 5118 2.3GHz 12-Core 256GB DDR4 2x 800GB SSD

4-Socket Xeon Server for Mission-Critical Workloads

The Dell PowerEdge R940 is a 3U rack server built for organisations that need dense, four-socket compute in a compact form factor. 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 256 GB of DDR4 2400 MHz registered ECC memory across 48 slots and two 800 GB SATA SSDs managed by a PERC H730P controller. Dual 1600 W platinum power supplies and iDRAC 9 Enterprise provide redundancy and remote management.

Upgrading from Dual-Socket or Lower-Core Platforms

Moving from a two-socket server or a four-socket system with fewer cores per CPU yields a significant jump in parallel throughput for virtualisation, in-memory databases and high-performance computing. The step is worth it when your workloads saturate the CPU or memory bandwidth of a smaller chassis and you need the 6 TB maximum memory ceiling without moving to a larger rack footprint. The PERC H730P supports RAID 0, 1, 5, 6, 10, 50 and 60 for flexible storage resilience.

Verify Rack Space, Power and Network Requirements

Confirm your rack can accommodate a 3U chassis with the included ready rails and front bezel. Ensure the facility provides adequate power distribution for dual 1600 W supplies and that cooling capacity matches the thermal output. The Intel X520/I350 daughter card delivers two 1 GbE and two 10 Gb SFP+ ports, so check that your top-of-rack switches have compatible SFP+ transceivers and cabling. The system uses LGA 3647 sockets and DDR4 memory only.
