Purpose-built 4-socket rack server

The Dell PowerEdge R940 is a 3U rack server equipped with four Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores. It ships with 128 GB of DDR4 registered ECC memory across 48 slots and includes a PERC H730P storage controller, two 300 GB 10K SAS drives, and dual 1600 W redundant power supplies.

Suited for dense multi-threaded workloads

This configuration targets organisations running virtualisation clusters, in-memory databases, or ERP systems that benefit from 48 total cores and a 6 TB memory ceiling. Buyers who need GPU acceleration, single-thread speeds above 3.2 GHz, or storage densities beyond eight 2.5-inch bays should evaluate alternative platforms.

Memory ceiling decides fit

The 48 DDR4 slots support up to 6 TB of registered ECC memory, making maximum capacity the primary filter for prospective buyers. If the intended workload fits within 128 GB today but may scale toward the terabyte range, the R940 provides headroom; otherwise a smaller 2-socket system may be more cost-effective.

Questions about this item

What rack height and rail kit does the PowerEdge R940 need?

The server is a 3U rack unit and ships with Ready Rails for standard rack installation.

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

All four sockets are populated at the factory; the common oversight is not confirming the H730P battery is seated so RAID cache protection is active.

Which components will need replacement first in this R940?

The two 300 GB 10K SAS drives and the PERC H730P controller battery are the likeliest items to require replacement over time.
