Four-Socket Xeon Gold 6142 Server

This DELL PowerEdge R940 is a 3U rack server system built for mission-critical workloads. 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. The system includes 512 GB of DDR4 2666 MHz registered ECC memory across 16 modules. Dual 1600 watt platinum power supplies provide redundancy.

Suits Dense Virtualisation And Database Work

Organisations consolidating virtual machines or running large in-memory databases benefit from the 64 total cores and 6 TB maximum memory capacity. The Dell PERC H730P controller supports RAID levels 0, 1, 5, 6, 10, 50 and 60 for flexible storage protection. Buyers needing GPU acceleration or single-threaded application speed should evaluate alternative platforms.

48 DIMM Slots Define Upgrade Path

The server provides 48 DDR4 memory slots, with 16 currently populated by 32 GB modules. This layout determines how far memory can scale toward the 6 TB limit and whether future additions require replacing existing sticks. The LGA 3647 sockets are fully occupied by the four installed CPUs, so processor upgrades are not possible without removal.
