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.

Küsimused selle toote kohta

What components are included and what must be purchased separately?

The server ships with four Xeon Gold 6142 processors, 128 GB DDR4 memory across eight 16 GB modules, eight 400 GB SATA SSDs, a PERC H730P controller with battery, a quad-port X520/I350 network card, iDRAC9 Enterprise, two 1600 W power supplies, rails and a bezel. Additional drives or memory must be bought separately.

Which memory configuration suits this 48-slot system?

The installed 128 GB uses eight 16 GB DDR4 2666 MHz registered ECC DIMMs, leaving 40 slots free. Populate in multiples of eight for balanced performance and expand up to the 6 TB maximum with compatible DDR4 modules.

How does the 2.6 GHz base clock with 3.7 GHz turbo translate to real workloads?

Each of the four 16-core Xeon Gold 6142 CPUs runs at 2.6 GHz base and can boost to 3.7 GHz, giving 64 cores total for parallel tasks such as virtualization, databases and analytics while the turbo frequency accelerates single-thread bursts.
