Mission-Critical Four-Socket Server

The Dell PowerEdge R940 is a 3U rack server built for workloads that demand four Intel Xeon Gold 6142 processors. Each CPU runs at 2.60 GHz with 16 cores and a 3.7 GHz turbo frequency. The system ships with 64 GB of DDR4 2666 MHz registered ECC memory across 48 slots. Eight 300 GB 10K SAS drives connect to a PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. Dual 1600 W platinum power supplies and iDRAC9 Enterprise remote management complete the package.

Ideal for Dense Compute and Virtualisation

This configuration suits organisations running large databases, virtualisation clusters or in-memory analytics that benefit from 64 total cores and up to 6 TB of memory capacity. The quad-port X520/I350 daughter card provides two 1 GbE and two 10 Gb SFP+ links for high-throughput networking. Buyers who need only one or two processor sockets, or who prefer solid-state storage over 10K SAS hard drives, should evaluate different platforms.

PERC H730P RAID Controller Decides Storage Topology

The installed PERC H730P 2 GB controller determines which RAID levels are available and whether the eight 2.5-inch bays can accommodate SAS or SATA drives. Its battery-backed cache enables write-back policies for RAID 5, 6, 50 and 60. Confirm that your application’s I/O profile matches these RAID options before deployment.

Questions about this item

What rack height does the PowerEdge R940 occupy?

The server is a 3U rack-mount unit and ships with ready rails and a front bezel for installation.

How are the four Xeon Gold 6142 processors installed in the R940?

All four LGA 3647 sockets are populated from the factory; the step often missed is applying the correct torque sequence to each CPU heat-sink retention bracket.

What memory upgrades does the R940 support later?

The system has 48 DDR4 slots and currently holds 64 GB in four 16 GB modules; it can be expanded up to 6 TB using registered ECC DDR4 2666 MHz DIMMs.
