Four-socket Xeon server for critical workloads

The PowerEdge R940 is a 3U rack server built for mission-critical applications that demand high core counts and large memory capacity. It ships with four Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores and a 3.7 GHz turbo frequency. This configuration targets organisations running virtualisation, in-memory databases or real-time analytics.

128 GB DDR4 registered ECC memory installed

The system includes 128 GB of DDR4 2666 MHz registered ECC memory across eight 16 GB modules, leaving 40 slots free for expansion up to 6 TB. The four LGA 3647 sockets are fully populated, so no additional processors can be added. Buyers who need more memory capacity must populate the remaining slots with compatible DDR4 RDIMMs.

Dual 1600 W platinum supplies

Two 1600 watt platinum-efficiency power supplies provide redundant, hot-swappable power for continuous operation. The PERC H730P controller with 2 GB cache manages the two installed 800 GB SATA SSDs and supports RAID levels 0, 1, 5, 6, 10, 50 and 60. Network connectivity uses a quad-port daughter card with two 1 GbE and two 10 Gb SFP+ interfaces.

Questions about this item

How do the four Xeon Gold 6148 processors perform in a real workload?

Each Xeon Gold 6148 runs at 2.4 GHz with 20 cores and can boost to 3.7 GHz, giving 80 total cores across four sockets for heavy multi-threaded tasks.

What does the PERC H730P controller limit in practice?

The H730P provides 12Gb/s SAS and SATA connectivity with 2GB cache and supports RAID 0, 1, 5, 6, 10, 50, 60 plus pass-through mode.

What does the 3U chassis need to fit in a rack?

The server occupies 3U of vertical space in a standard rack and ships with ready rails and a front bezel for installation.
