DELL PowerEdge R940 3U rack server 4x Xeon Gold 6142 2.6GHz 16-core 768GB DDR4 8x 2.4TB SAS H730P

Four-socket Xeon Gold 6142 server

The PowerEdge R940 packs four Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores and a 3.7 GHz turbo frequency. It delivers 768 GB of DDR4 2666 MHz registered ECC memory across 24 modules. The 3U rack chassis supports up to 6 TB total memory capacity using 48 DIMM slots. This configuration targets organisations running memory-intensive databases, virtualisation clusters or analytics workloads that demand high core counts and large memory footprints.

Redundant 1600 W platinum power supplies

Dual hot-swap 1600 W platinum-efficiency units provide N+1 redundancy for continuous operation under full load. The system draws power across both supplies to balance thermal output and reduce strain on any single module. Fan speeds adjust dynamically to workload, keeping acoustic levels appropriate for data-centre aisles. The LGA 3647 socket design and Intel C620 chipset ensure stable power delivery to all four processors during sustained compute tasks.

PERC H730P controller with battery-backed cache

The Dell PERC H730P 2 GB controller enables RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through modes for flexible storage layouts. Its battery-backed cache protects in-flight writes during unexpected power loss. Eight 2.4 TB 10K SAS drives ship installed, delivering high-capacity sequential throughput for logging or archival workloads. The X520/I350 daughter card adds two 1 GbE and two 10 Gb SFP+ ports, while iDRAC 9 Enterprise provides dedicated out-of-band management. ReadyRails and front bezel are included for immediate rack integration.
