Four-Socket Xeon Gold 6142 Platform

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 ships with 256 GB of DDR4 registered ECC memory across 48 slots and a PERC H730P storage controller. This configuration targets organisations that run large in-memory databases or virtualisation clusters requiring high core counts in a compact rack footprint.

Sustained Multi-Threaded Throughput

Four 16-core CPUs deliver 64 threads at a base frequency of 2.6 GHz, with a 3.7 GHz turbo ceiling for burst phases. The 1600 W redundant platinum power supplies and hot-swap design keep the system online during continuous heavy compute loads. Eight memory channels per socket feed the cores, reducing contention when many virtual machines or database workers are active simultaneously.

SAS Storage and Network Ceiling

The H730P controller operates at 12 Gb/s over SAS and SATA, supporting RAID levels 0, 1, 5, 6, 10, 50 and 60. Two 300 GB 10 K SAS drives are installed in the eight-bay 2.5-inch chassis, leaving six bays open for expansion. Network I/O is handled by an Intel X520/I350 daughter card providing two 10 Gb SFP+ ports and two 1 GbE ports, setting the practical bandwidth limit for east-west traffic.

Questions about this item

How loud and hot does the R940 get with four Xeon Gold 6142 CPUs and dual 1600 Watt PSUs running continuously?

Four 16-core Xeon Gold 6142 processors at 2.6 GHz with 3.7 GHz turbo and two 1600 W platinum power supplies mean substantial heat output; the 3U chassis uses redundant hot-swap fans to manage thermals under sustained load.

What cabling and drives must I already have to use the H730P controller and the eight 2.5-inch bays?

The PERC H730P 2 GB controller supports SAS and SATA drives with RAID 0/1/5/6/10/50/60; the eight 2.5-inch bays accept SAS or SATA disks, and the system ships with two 300 GB 10K SAS drives installed.

Will my existing DDR4 2666 MHz registered ECC modules work alongside the 256 GB already installed in the 48 memory slots?

The R940 has 48 DDR4 slots supporting up to 6 TB total; eight 32 GB DDR4 2666 MHz registered ECC modules are installed, so additional modules must match DDR4 registered ECC specification to function correctly.
