DELL PowerEdge R940 3U rack server 4× Xeon Gold 6142 2.6 GHz 16-core 768 GB DDR4 2× 400 GB SSD

Dell PowerEdge R940 for mission-critical workloads

The Dell PowerEdge R940 is a 3U rack server built for mission-critical applications and real-time decisions. Four Intel Xeon Gold 6142 processors at 2.6 GHz with 16 cores each deliver 64 total cores. 768 GB of DDR4 2666 MHz registered ECC memory is installed across 24 modules. The system supports up to 6 TB maximum capacity across 48 slots.

Verify rack space power and network before ordering

Confirm your rack can accommodate a 3U form factor and that your facility provides redundant power circuits for the dual 1600 W platinum supplies. The storage controller is a Dell PERC H730P with 2 GB cache supporting SAS and SATA drives in RAID 0, 1, 5, 6, 10, 50, 60 and pass-through. Networking uses an Intel X520/I350 quad-port daughter card with two 1 GbE and two 10 Gb SFP+ connections. iDRAC 9 Enterprise provides remote management.

Dual 1600 W supplies handle peak load efficiently

Redundant 1600 watt platinum power supplies share the load and maintain operation if one unit fails. The 3U chassis uses multiple hot-swap fans that adjust speed based on inlet temperature and component demand. Acoustic output rises under full CPU utilisation but remains within typical data-centre limits. Power draw scales with the four-socket configuration and installed memory population.
