Four-socket Xeon server for dense compute

The Dell PowerEdge R940 fits four Intel Xeon Gold 6148 processors into a 3U rack chassis. Each CPU delivers 20 cores at 2.4 GHz with a 3.7 GHz turbo frequency. The system ships with 256 GB of DDR4 2666 MHz registered ECC memory across 48 slots. It targets organisations running virtualisation, databases or in-memory analytics that need high core counts in limited rack space.

Eight-bay front storage with hardware RAID

Eight 2.5-inch drive bays accept SATA or SAS media and connect to a PERC H730P controller with 2 GB cache. The controller supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Two 400 GB SATA SSDs are installed from the factory. Redundant hot-swap 1600 W platinum power supplies and included sliding rails simplify deployment and ongoing maintenance.

Quad-port networking and remote management

A daughter card provides two 1 GbE and two 10 Gb SFP+ ports for flexible uplink choices. iDRAC 9 Enterprise enables out-of-band monitoring, firmware updates and virtual console access without touching the host OS. Redundant power and efficient platinum supplies keep thermal load manageable in normal operation while the 3U form factor allows adequate airflow for sustained workloads.

Questions about this item

What storage interface does the PERC H730P controller use, and what speed does it cap at?

The Dell PERC H730P 2GB controller runs on a 12Gb/s SAS/SATA interface and supports RAID 0, 1, 5, 6, 10, 50, 60 and Pass-Through modes.

What physical space and mounting hardware does the R940 need to fit in a rack?

The server is a 3U rack unit and includes ready rails and a front bezel for installation.

How is the system memory installed, and what mistake should be avoided?

The 256GB ships as eight 32GB DDR4 2666MHz Registered ECC modules; populate all 48 slots evenly across the four processors to avoid unbalanced memory channels.
