Four-socket Xeon Gold server

The Dell PowerEdge R940 is a 3U rack-mount server system built for organisations that need high core counts in a compact form factor. It ships with four Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores and a 3.7 GHz turbo frequency. The system includes 64 GB of DDR4-2666 registered ECC memory installed across four modules. Redundant 1600 W platinum power supplies and iDRAC 9 Enterprise remote management are standard.

Suits dense compute; not for massive local storage

This platform suits virtualisation clusters, database nodes and analytics workloads that benefit from 64 physical cores and up to 6 TB of DDR4 capacity across 48 DIMM slots. The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 with a 2 GB cache. Buyers who need more than eight 2.5-inch drive bays or who require a higher density of local storage without external enclosures should evaluate other platforms.

Eight 2.5-inch bays define internal capacity

The chassis provides eight hot-swap 2.5-inch SAS/SATA trays and no drives are included. This bay count is the primary constraint for onboard storage capacity and RAID layout options. Network connectivity is delivered through a quad-port daughter card offering two 1 GbE and two 10 Gb SFP+ interfaces. Expansion beyond the eight bays requires external JBODs or a different chassis.

Questions about this item

What storage interface does the PERC H730P controller support and what is its maximum throughput?

The Dell PERC H730P 2GB controller handles 12Gb/s SAS and SATA drives and supports RAID 0, 1, 5, 6, 10, 50, 60 plus pass-through mode.

What rack depth and mounting hardware are required for the 3U chassis?

The unit ships with Dell Ready Rails and a front bezel for standard 4-post racks; allow enough depth for the 3U enclosure plus cable clearance at the rear.

How are the four Xeon Gold 6142 processors installed and what is the common mistake?

All four LGA 3647 sockets are already populated with 16-core 2.6 GHz CPUs; the typical error is adding a fifth processor when the maximum is four.
