Quad-socket Xeon Gold 6142 server

This Dell PowerEdge R940 is a 3U rack server equipped with four Intel Xeon Gold 6142 processors running at 2.6 GHz with 16 cores each. The system includes 256 GB of DDR4 registered ECC memory across eight 32 GB modules. Eight 1.2 TB 10K SAS drives connect through a PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. Dual 1600 W platinum power supplies, iDRAC9 Enterprise, quad-port networking and rails are installed.

Suits dense virtualisation and database workloads

Organisations running heavily threaded applications, large in-memory databases or consolidated virtual machines benefit from the 64 combined cores and 6 TB maximum memory capacity. The 48 DIMM slots allow substantial future expansion. Buyers who need GPU acceleration, single-thread performance above 3.7 GHz turbo or storage beyond eight 2.5-inch bays should evaluate alternative platforms. The fixed four-processor configuration also limits scaling past the installed CPU count.

PERC H730P controller with 2 GB cache

The integrated Dell PERC H730P provides 12 Gb/s SAS/SATA connectivity with battery-backed cache enabling all listed RAID levels and pass-through mode. This controller determines which drive types and RAID configurations are supported. Eight 1.2 TB 10K SAS drives are populated in the 2.5-inch bays. The storage subsystem is defined by this controller and the installed drive set.

Questions about this item

What rack space and power connections are needed to install this 3U server?

The R940 occupies 3U of rack height and ships with two redundant 1600 W power supplies; each requires its own PDU feed for full redundancy.

Will the PERC H730P controller recognise the existing 1.2 TB SAS drives already in the chassis?

Yes, the H730P is a 12 Gb/s SAS/SATA controller with battery-backed cache and supports RAID 0/1/5/6/10/50/60, so the eight installed 1.2 TB 10K SAS drives are managed natively.

How can I confirm all four Xeon Gold 6142 processors are active after first boot?

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