Four-Socket Xeon Server for Critical Workloads

The Dell PowerEdge R940 is a 3U rack server equipped with four Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores. It includes 128 GB of DDR4 registered ECC memory across 48 slots and a PERC H730P storage controller managing eight 800 GB SATA SSDs. Dual 1600 W redundant power supplies and iDRAC9 Enterprise remote management support continuous operation.

Suited for Multi-Threaded Databases

This system targets organisations running memory-intensive databases, large-scale virtualisation clusters, or real-time analytics that benefit from 64 total cores and up to 6 TB maximum memory capacity. Buyers who need fewer than four processors, require a different storage interface than SATA or SAS, or operate in a smaller rack footprint should consider alternative platforms.

Four Installed Processors Define Maximum Compute

The server ships with the maximum of four Xeon Gold 6142 CPUs installed, delivering 64 cores and 128 threads in a single 3U chassis. This fixed processor count determines whether the platform matches workloads that demand the highest core density per rack unit versus those that can scale across multiple two-socket nodes.

Questions about this item

Will the four Xeon Gold 6142 processors and 128GB DDR4 memory work with my existing DDR4 registered ECC modules?

The server uses DDR4 2666MHz registered ECC memory across 48 slots; match speed, rank and voltage when adding modules.

How can I verify the PERC H730P controller and all eight 800GB SSDs are healthy after installation?

Check the controller BIOS during boot and use iDRAC 9 Enterprise to confirm RAID status, drive health and battery condition.

Which items come in the box and what must I purchase separately for network connectivity?

The system includes bezel, rails, two 1600W PSUs, X520/I350 daughter card with two 1GbE and two 10Gb SFP+ ports; SFP+ transceivers and cables are not included.
