Four-socket Xeon server for mission-critical

The Dell PowerEdge R940 is a 3U rack server built around four Intel Xeon Gold 6148 processors, each running at 2.40 GHz with 20 cores. It ships with 768 GB of DDR4 2666 MHz registered ECC memory across 24 modules. Eight 2.4 TB 10K SAS hard drives connect to a PERC H730P controller with 2 GB cache and battery backup.

Tool-less rails and hot-swap components simplify

Ready Rails and a front bezel are included for quick rack mounting. All eight 2.5-inch drive bays and both 1600 W platinum power supplies support hot-swap replacement, so failed parts can be exchanged without downtime. The PERC H730P battery protects cached writes during unexpected power loss.

Verify rack depth, power feeds

Confirm your cabinet can accommodate a 3U chassis with cable clearance for quad-port networking (two 1 GbE and two 10 Gb SFP+ ports). Two separate high-current circuits are needed for redundant 1600 W supplies. Ensure SAS backplane cabling matches the H730P controller and that iDRAC 9 Enterprise has a dedicated management network path.

Questions about this item

How can I confirm the four Xeon Gold 6148 processors are all recognised after installation?

The iDRAC9 Enterprise remote management interface displays the full CPU inventory, including core count and clock speeds, so you can verify all four 20-core processors are detected.

Which components are included and which must be sourced separately?

The chassis ships with four Xeon Gold 6148 CPUs, 768 GB DDR4 memory across 24 modules, eight 2.4 TB SAS drives, PERC H730P controller, X520/I350 quad-port network card, two 1600 W power supplies, rails and bezel.

Which memory configuration should I select if I want to expand beyond the installed 768 GB?

The system has 48 DDR4 slots and supports up to 6 TB; add registered ECC DDR4 modules in matched sets to fill the remaining 24 slots for maximum capacity.
