CPU Model Gold 6142

  • 64GB DDR4 ECC memory supports demanding workloads
  • Four Xeon Gold 6142 processors deliver 64 total cores
  • PERC H730P controller enables RAID 0/1/5/6/10/50/60
  • Dual 800GB SATA SSDs provide fast boot storage
  • iDRAC9 Enterprise allows full remote server management

Four-socket Xeon server for mission-critical

The PowerEdge R940 fits four Intel Xeon Gold 6142 processors, each with 16 cores at 2.6 GHz and 3.7 GHz turbo, into a 3U rack chassis. Sixty-four gigabytes of DDR4-2666 registered ECC memory are installed across 48 slots, leaving room to scale toward the 6 TB maximum. The platform targets databases, virtualization hosts and real-time analytics that demand high core counts in a compact footprint.

Redundant 1600 W platinum supplies

Dual 1600 watt platinum-efficiency power supplies share the load and allow one unit to fail without downtime. Hot-swap capability lets technicians replace a supply while the system runs. The four-socket design and fully populated memory channels draw substantial power under load, so the redundant architecture protects uptime during sustained compute tasks.

Eight 2.5-inch bays with PERC H730P and quad-port

The front bay area accepts eight 2.5-inch SATA or SAS drives; two 800 GB SATA SSDs are installed and managed by a PERC H730P controller with 2 GB cache supporting RAID 0, 1, 5, 6, 10, 50 and 60. A daughter card adds two 1 GbE and two 10 Gb SFP+ ports for flexible fabric connectivity. iDRAC 9 Enterprise provides dedicated remote management, and ready rails with a front bezel simplify rack installation.

Questions about this item

How do I install the four Xeon Gold 6142 processors, and which step is commonly missed?

Seat each CPU in its LGA 3647 socket, apply thermal paste, attach the heatscrews in the labelled diagonal sequence, then verify all 48 DDR4 slots are populated per the memory-configuration guide so the system posts with four processors.

What maintenance or replacement will the PERC H730P controller need later?

The H730P uses a 2 GB cache backed by a battery; plan to replace that battery module when iDRAC 9 reports a degraded or failed cache-battery status.

What limit appears first when the R940 runs sustained workloads?

The dual 1600 W platinum power supplies cap total draw; sustained turbo across all 64 cores plus memory, storage and fan overhead will reach the PSU ceiling before thermal throttling engages.
