Mission-critical 4-socket server

The Dell PowerEdge R940 is a 3U rack system built for databases and real-time analytics that demand four Intel Xeon Gold 6142 processors. Each CPU delivers 16 cores at 2.6 GHz with a 3.7 GHz turbo frequency. The platform targets organisations that need maximum core density in a compact rack footprint.

6 TB DDR4 ceiling

Memory scales to 6 TB across 48 DDR4 slots using registered ECC modules, while the installed configuration provides 128 GB at 2666 MHz. The Intel C620 chipset and LGA 3647 sockets support the full four-processor complement without further upgrades.

Sustained throughput with hardware RAID

The PERC H730P controller with 2 GB cache and battery backs RAID 0, 1, 5, 6, 10, 50 and 60 for continuous write-heavy workloads. Dual 1600 W platinum power supplies and hot-swap bays keep the array online during drive replacement or power-module failure.

Questions about this item

What does the 2.6 GHz base clock on the four Xeon Gold 6142 CPUs deliver once the server is running live workloads?

Each of the four processors runs at 2.6 GHz base and can turbo to 3.7 GHz, giving 64 total cores for heavy multi-threaded applications.

How does the PERC H730P controller limit drive performance in this configuration?

The H730P provides 12 Gb/s SAS/SATA connectivity with 2 GB cache and supports RAID 0, 1, 5, 6, 10, 50, 60 plus pass-through mode.

What physical space and mounting hardware does the 3U chassis require in a standard rack?

The unit occupies 3U of rack height and ships with ready rails and a front bezel for direct installation.
