PowerEdge R940 3U four-socket server

The Dell PowerEdge R940 is a 3U rack-mount server that holds four Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores. It ships with 768 GB of DDR4 memory installed across 24 modules and includes a PERC H730P storage controller with battery backup. Two 400 GB SATA SSDs and dual 1600 W redundant power supplies are fitted.

Suits dense compute workloads.

This system targets databases, virtualisation clusters and analytics jobs that benefit from four sockets and a large memory footprint in a compact 3U chassis. Organisations that only require one or two processors, or that need more than eight 2.5-inch drive bays, should evaluate alternative platforms.

Four-socket Xeon Gold 6148 configuration decides fit

The defining specification is the four-socket layout populated with Xeon Gold 6148 CPUs, providing 20 cores per processor at 2.4 GHz base frequency with 3.7 GHz turbo. That processor count and core density determine whether the server matches the licensing, threading and memory-channel requirements of the intended workload.

Questions about this item

What rack and power infrastructure do I need to install this 3U server?

The chassis occupies 3U of rack space and requires two 1600 W hot-swap power supplies; both must be connected to separate circuits for full redundancy.

Can I keep my existing 12 Gb/s SAS drives and SATA SSDs when migrating to the PERC H730P controller?

Yes, the H730P supports both 12 Gb/s SAS and SATA devices, so current drives can be reused in the eight 2.5" bays.

How do I verify the iDRAC9 Enterprise remote management is operational after first boot?

Open a browser to the iDRAC IP shown on the front LCD, log in with the default credentials, and confirm the dashboard reports all four CPUs, 768 GB memory and both 400 GB SSDs as healthy.
