CPU Model Gold 6142

  • Four-socket Xeon Gold 6142 processors deliver 64 total cores for heavy workloads
  • 512GB DDR4 ECC memory across 16 modules supports large databases and virtualisation
  • Eight 800GB SATA SSDs provide fast redundant storage in a 2.5" form factor
  • PERC H730P controller enables RAID 0/1/5/6/10/50/60 with battery-backed cache
  • Dual 1600W platinum PSUs and iDRAC9 Enterprise ensure uptime and remote management

Four-Socket Xeon Server

The Dell PowerEdge R940 is a 3U rack server populated with four Intel Xeon Gold 6142 processors running at 2.6 GHz, each offering 16 cores. It ships with 512 GB of DDR4 2666 MHz registered ECC memory across 16 modules and eight 800 GB SATA solid-state drives managed by a PERC H730P controller. Dual 1600 W platinum power supplies, iDRAC 9 Enterprise, quad-port networking and rails are included.

Suited For Dense Compute

This configuration suits organisations running memory-intensive databases, virtualisation hosts or analytics workloads that benefit from 64 total cores and half a terabyte of RAM in a compact 3U form factor. Buyers who need more than 48 DIMM slots, more than eight 2.5-inch drive bays, or a different storage interface should evaluate other platforms.

512 GB DDR4 Installed Memory

The system arrives with 512 GB of DDR4 memory installed in 16 of the 48 available slots, leaving room to scale toward the 6 TB maximum. Confirm that your workload fits within the current capacity or plan for additional DDR4 modules before deployment.
