Dell PowerEdge R940 3U rack server

The Dell PowerEdge R940 is a 3U rack server built for compute-intensive workloads. Four Intel Xeon Gold 6148 processors each provide 20 cores running at 2.4 GHz with a 3.7 GHz turbo frequency. The system includes 256 GB of DDR4 registered ECC memory across eight 32 GB modules. Dual 1600 W platinum power supplies and iDRAC 9 Enterprise remote management are fitted as standard.

Suited for high-density virtualisation

This server suits organisations that need maximum core density in a 3U form factor with redundant power and advanced remote management. The eight 2.5-inch drive bays and PERC H730P controller support SAS and SATA drives in multiple RAID modes. Buyers who require installed solid-state drives or pre-configured storage arrays should look at a different configuration. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ connections for flexible networking.

48 DDR4 memory slots support up to 6 TB

The platform provides 48 DIMM slots with a maximum memory capacity of 6 TB using DDR4 registered ECC modules. Memory runs at 2666 MHz and the installed 256 GB occupies eight of the available slots. This specification determines how far the system can scale for memory-bound applications such as in-memory databases or large virtual machine farms.

Questions about this item

What sustained thermal load do the dual 1600 W platinum power supplies present to the rack?

The server ships with two redundant 1600 W platinum power supplies that can deliver full output continuously under heavy CPU and memory workloads.

How loud are the system fans when all four 20-core Xeon Gold 6148 CPUs run at 3.7 GHz turbo for extended periods?

Fan speed ramps with inlet temperature and CPU load; under sustained turbo the chassis moves significantly more airflow than at idle, producing noticeable datacentre-level noise.

Which drive trays and backplane connectors are already fitted so I can add my own 2.5" SAS or SATA drives?

Eight 2.5-inch hot-swap trays wired to the PERC H730P controller are installed; the backplane accepts both SAS and SATA drives without additional cabling.
