DELL PowerEdge R940 3U rack server 4× Xeon Gold 6142 2.6GHz 16-core 128GB DDR4 8× 400GB SSD H730P

Four-socket Xeon Gold 6142 server

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 and a 3.7 GHz turbo frequency. It ships with 128 GB of DDR4 2666 MHz registered ECC memory across 48 available slots. The system targets organisations that run mission-critical workloads and real-time analytics in a compact footprint.

Check power, rack space and drive bays

Verify that your facility can supply redundant 1600 W platinum-efficiency power feeds and that the cabinet accepts a 3U form factor with ready rails. The chassis provides eight 2.5-inch SATA drive bays populated with 400 GB enterprise SSDs behind a PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. Network connectivity uses an Intel X520/I350 daughter card delivering two 1 GbE and two 10 Gb SFP+ ports, while iDRAC 9 Enterprise handles remote management.

Sustained load on four CPUs and storage array

Under continuous demand the four 16-core CPUs maintain elevated frequencies within the thermal envelope of the 3U chassis, and the redundant power supplies share load without interruption. The H730P controller’s battery-backed cache sustains write throughput during extended RAID rebuilds or heavy transaction processing. Memory capacity can scale to 6 TB across all 48 slots, allowing the platform to keep large working sets resident without paging.
