Four-socket Xeon Gold server

The Dell PowerEdge R940 is a 3U rack server built for heavy enterprise workloads. It ships with four Intel Xeon Gold 5118 processors, each running at 2.30 GHz with 12 cores. The system includes 256 GB of DDR4 registered ECC memory across eight 32 GB modules. Dual 1600 W platinum power supplies and iDRAC 9 Enterprise remote management complete the package.

Suits virtualisation and database clusters

This configuration targets organisations that run large virtual machine farms, in-memory databases or high-transaction ERP systems. The quad-socket design and 48 DIMM slots support up to 6 TB of memory for scale-up scenarios. Buyers who need GPU acceleration, single-threaded performance above 3.2 GHz turbo or a chassis smaller than 3U should evaluate other platforms.

48 DDR4 DIMM slots define maximum memory

The server provides 48 memory slots populated with eight 32 GB DDR4 2400 MHz modules today. Expansion is limited by this slot count and the 6 TB architectural ceiling. Confirm that your memory roadmap fits within these constraints before purchase.

Questions about this item

How are the four Xeon Gold 5118 processors installed, and what step is often missed?

The four processors drop into the four LGA 3647 sockets on the system board; the step often missed is applying the correct torque sequence on each retention bracket before closing the load plate.

Which components will need replacement first during the server's life?

The PERC H730P controller battery and the two 1600 watt power supply fans are the first parts that typically require replacement.

What limit appears first when the R940 runs sustained heavy workloads?

The 1600 watt redundant power supplies set the first sustained ceiling; total draw above their combined rating triggers throttling or shutdown.
