Quad-socket Xeon Gold 6142 server

The Dell PowerEdge R940 is a 3U rack server equipped with four Intel Xeon Gold 6142 processors running at 2.6 GHz with a 3.7 GHz turbo frequency. Each processor provides 16 cores, delivering 64 cores total for heavy multi-threaded workloads. The system ships with 768 GB of DDR4 registered ECC memory across 24 modules.

Upgrade from dual-socket or lower-core platforms

Moving from a dual-socket server or a configuration with fewer cores per CPU adds significant parallel capacity for virtualisation, database and analytics tasks. The jump is worthwhile when licensing, memory bandwidth or thread count become bottlenecks on smaller platforms. The R940 also supports up to 6 TB of memory for future expansion.

Fits 3U racks with redundant power and high-speed

The chassis occupies a standard 3U rack space and includes ready rails and a front bezel for quick installation. Dual 1600 W platinum power supplies provide hot-swap redundancy. An Intel X520/I350 daughter card adds two 1 GbE and two 10 Gb SFP+ ports, while the PERC H730P controller manages eight 800 GB SATA SSDs with RAID flexibility.

Questions about this item

What rack height and mounting hardware does the PowerEdge R940 require?

The server occupies 3U of rack space and ships with ready rails for installation in a standard rack.

How are the four Xeon Gold 6142 processors installed, and what step is often missed?

All four CPU sockets are already populated with the 2.6 GHz 16-core processors; the common oversight is forgetting to verify that the iDRAC9 Enterprise licence is activated for remote management.

Which components will need replacement first in the storage subsystem?

The eight 800 GB SATA SSDs and the PERC H730P controller's battery-backed cache are the primary items that will require replacement as they age.
