Four-socket Xeon server for critical workloads

The PowerEdge R940 packs four Intel Xeon Gold 6142 processors at 2.6 GHz with 16 cores each, delivering 64 total cores in a 3U rack form factor. 256 GB of DDR4 registered ECC memory across 48 slots supports large datasets and virtualization density. Eight 2.4 TB SAS hard drives on a PERC H730P controller provide high-capacity redundant storage for databases and enterprise applications.

Check power, networking

Dual 1600 W redundant power supplies require appropriate PDU circuits and voltage in your facility. The X520/I350 daughter card supplies two 1 GbE and two 10 Gb SFP+ ports, so confirm your switch has compatible transceivers and cabling. Verify 3U clearance and rail depth in your cabinet, and ensure the LGA 3647 socket platform matches your existing infrastructure management tools.

Included rails, bezel

ReadyRails and the front bezel enable tool-less mounting and a clean rack appearance without extra kits. iDRAC 9 Enterprise provides full remote console, virtual media and lifecycle automation out of the box, reducing the need for on-site visits. The PERC H730P battery-backed cache protects write data during power loss, and the quad-port network card eliminates separate NIC purchases for 10 Gb connectivity.
