Four-socket Xeon Gold 6148 server

The Dell PowerEdge R940 is a 3U rack server built around four Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores. It ships with 512 GB of DDR4 registered ECC memory across 48 slots and includes a PERC H730P controller with battery-backed cache. Two 800 GB SATA SSDs and quad-port 1/10 GbE networking are installed. Dual 1600 W platinum power supplies and iDRAC9 Enterprise remote management complete the package.

Upgrade from dual-socket or lower-core platforms

This system replaces dual-socket servers or older four-socket boxes that cannot reach 80 total cores and 6 TB maximum memory capacity. The jump is worth it when workloads such as large in-memory databases, virtualisation clusters or real-time analytics need the full 48 DIMM slots and four-processor scaling in a single 3U chassis. Buyers staying with smaller memory footprints or fewer cores will not use the headroom this platform provides.

Verify rack depth, power feeds and drive count

Confirm the rack can accommodate the chassis depth and that two 1600 W power circuits are available for redundant operation. The front bay holds eight 2.5-inch drives but only two SSDs are included; additional SATA or SAS drives must be sourced separately. Ensure the PERC H730P RAID modes match the planned storage layout and that iDRAC9 Enterprise licensing suits the management strategy.

Questions sur cet article

What rack height does the 3U PowerEdge R940 require, and what mounting hardware is included?

The server fits a 3U rack space and includes Dell Ready Rails plus a front bezel for installation.

How are the four Xeon Gold 6148 processors and 512GB of DDR4 memory installed, and what step is often missed?

All four CPU sockets are populated and 16 DIMM slots are filled at the factory; the step often missed is verifying the memory configuration matches the 2666MHz registered ECC specification before adding modules.

Which components in the R940 are hot-swappable and will need replacement over time?

The two 800GB SATA SSDs and both 1600W platinum power supplies are hot-swappable; the PERC H730P controller battery will also require periodic replacement.
