Four-Socket Xeon Gold 5118 Server

The Dell PowerEdge R940 is a 3U rack server equipped with four Intel Xeon Gold 5118 processors running at 2.30 GHz with 12 cores each. It includes 512 GB of DDR4 registered ECC memory across 16 modules and two 800 GB SATA solid-state drives managed by a PERC H730P RAID controller. Dual 1600 W redundant power supplies and iDRAC9 Enterprise remote management complete the configuration.

Suited for dense compute workloads

This system targets organisations that need high core counts and large memory capacity in a compact rack footprint for virtualisation, database or analytics workloads. Buyers who require more than two internal drives, additional PCIe expansion slots or a non-rack mounting option should evaluate alternative platforms because the chassis prioritises CPU density and redundant power in a 3U form factor.

48 DDR4 slots support up to 6 TB

The server provides 48 DDR4 memory slots with a maximum supported capacity of 6 TB, allowing substantial future memory expansion beyond the 512 GB installed. This headroom determines whether the platform can grow with increasing dataset sizes or virtual machine density over its service life.

Questions about this item

Should I pick the 800 GB SATA SSDs or add more drives to the eight 2.5-inch bays?

The server ships with two 800 GB SATA SSDs and six empty 2.5-inch bays; the PERC H730P supports SATA and SAS so you can add matching SSDs or larger capacity drives as needed.

What does the 2.3 GHz base clock with 3.2 GHz turbo mean for a four-socket Xeon Gold 5118 configuration?

Forty-eight cores run at 2.3 GHz base and can boost to 3.2 GHz under load, giving high multi-thread throughput for virtualisation or database workloads.

How does the 12 Gb/s SAS controller limit the installed SATA SSDs?

The PERC H730P runs at 12 Gb/s SAS but the fitted drives are SATA 6 Gb/s, so each SSD is capped at the SATA link speed.
