CPU Model Gold 6142

  • Four 16-core Xeon Gold 6142 CPUs deliver 64 total cores for heavy workloads
  • 256GB DDR4 2666MHz registered ECC memory supports large datasets with error correction
  • Eight 400GB enterprise SATA SSDs on a PERC H730P RAID controller provide fast redundant storage
  • Dual 10GbE SFP+ plus dual 1GbE ports enable high-throughput networking
  • iDRAC9 Enterprise and redundant 1600W platinum PSUs ensure remote management and power resilience

Four-socket Xeon Gold server

The Dell PowerEdge R940 is a 3U rack system built for mission-critical workloads that demand high core counts and large memory capacity. It ships with four Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores and a 3.7 GHz turbo frequency. This configuration suits organisations running virtualisation clusters, in-memory databases or real-time analytics platforms.

256 GB DDR4 registered ECC memory

The system includes 256 GB of DDR4 2666 MHz registered ECC memory populated across eight 32 GB modules. With 48 total DIMM slots and a maximum capacity of 6 TB, the platform leaves ample room for future expansion. Buyers who need the full 6 TB from day one will need to populate the remaining 40 slots with compatible modules.

PERC H730P controller with eight 400 GB SSDs

Storage is handled by a Dell PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Eight 400 GB SATA 2.5-inch SSDs are installed in the front eight-bay chassis, leaving no empty drive bays for additional 2.5-inch devices. The board also provides a quad-port network daughter card with two 1 GbE and two 10 Gb SFP+ connections, while dual 1600 W platinum power supplies and iDRAC 9 Enterprise complete the infrastructure-ready package.

Questions about this item

What does having four 16-core Xeon Gold 6142 CPUs at 2.6 GHz actually deliver in a live workload?

The system provides 64 physical cores running at a 2.6 GHz base frequency with a 3.7 GHz turbo ceiling, giving dense multi-threaded throughput for virtualization, databases or analytics in a single 3U chassis.

How does the PERC H730P controller and SATA SSD mix limit real-world drive performance?

The H730P runs on a 12 Gb/s SAS/SATA link with 2 GB cache and supports RAID 0/1/5/6/10/50/60, but the eight installed 400 GB SSDs are SATA 6 Gb/s devices, so each drive tops out at the SATA interface speed.

What physical space and mounting hardware does the 3U R940 need to go into a rack?

The server is a 3U rack unit and ships with Ready Rails plus a front bezel for installation in a standard four-post rack.
