DELL PowerEdge R940 3U Rack Server 4x Xeon Gold 6142 2.6GHz 16C 512GB DDR4 8x 300GB SAS H730P

Quad-socket Xeon Gold 6142 server

The Dell PowerEdge R940 is a 3U rack server populated with four Intel Xeon Gold 6142 processors. Each CPU runs at 2.6 GHz with 16 cores, delivering 64 cores total for heavy multi-threaded workloads. The system ships with 512 GB of DDR4 2666 MHz registered ECC memory across 16 modules. It targets organisations running large databases, virtualisation clusters or in-memory analytics.

Upgrade from dual-socket or lower core counts

Moving to four sockets is worthwhile when a dual-socket box hits memory-channel or core-count limits that stall throughput. The R940 supports up to 6 TB of DDR4 across 48 slots, so the jump makes sense for workloads that need more memory bandwidth than two CPUs can provide. Buyers who need more storage bays than the eight 2.5-inch SAS slots provided should look elsewhere.

Sustained load behaviour with redundant 1600 W power

Dual 1600 W platinum power supplies and hot-swap redundancy keep the platform stable during continuous operation. The PERC H730P controller with 2 GB cache maintains RAID performance across the eight 300 GB 10K SAS drives under steady write streams. iDRAC 9 Enterprise enables remote monitoring and firmware updates without taking the server offline.
