Mission-critical 4-socket server

The Dell PowerEdge R940 is a 3U rack server built for heavy database, virtualisation and analytics workloads. Four Intel Xeon Gold 6142 processors deliver 64 total cores at 2.6 GHz with 3.7 GHz turbo. 256 GB of DDR4 registered ECC memory and a PERC H730P controller with 2 GB cache support RAID 0, 1, 5, 6, 10, 50 and 60 across eight 300 GB 10 K SAS drives.

Suited for dense compute, not maximum drive count

Organisations that need high core density and redundant power in a compact 3U form factor will benefit from the four-socket design, quad-port 1 GbE and 10 GbE networking, and iDRAC 9 Enterprise remote management. Buyers who require more than eight 2.5-inch drive bays or a different storage controller feature set should evaluate other platforms.

Four Xeon Gold 6142 CPUs define capacity

The server ships with the maximum of four processors installed, fixing the core count at 64 and the memory ceiling at 6 TB across 48 DDR4 slots. This processor configuration determines whether the system meets the licensing and performance thresholds of the target application.

Questions about this item

How can I verify the four Xeon Gold 6142 processors are detected after first boot?

Open the iDRAC9 Enterprise interface or the system BIOS; both will show four CPUs, each reporting 16 cores at 2.6 GHz with 3.7 GHz turbo.

What storage and network hardware arrive pre-installed, and what must I add for extra drive bays?

Eight 300 GB 10K SAS drives and the PERC H730P 2 GB controller are installed; the X520/I350 daughter card provides two 1 GbE and two 10 Gb SFP+ ports. Empty 2.5-inch bays accept additional SAS or SATA drives.

Which memory configuration matches the factory 256 GB setup?

The server ships with eight 32 GB DDR4 2666 MHz registered ECC modules, filling 8 of the 48 DIMM slots.
