Four-socket Xeon Gold server for dense compute

The PowerEdge R940 packs four Intel Xeon Gold 5118 processors at 2.3 GHz with 12 cores each into a 3U rack chassis. It ships with 128 GB of DDR4 registered ECC memory across eight 16 GB modules. The system targets organisations that run virtualised workloads, in-memory databases or high-throughput transaction processing where core count and memory capacity matter more than single-thread speed.

PERC H730P controller and eight 600 GB SAS drives

The bundled Dell PERC H730P adds 2 GB of cache and supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Eight 2.5-inch 10 K RPM SAS drives provide 600 GB each on a 12 Gb/s interface. Buyers who need more storage bays or all-flash arrays will find the eight-bay front panel limiting.

3U form factor with dual 1600 W supplies

The 3U height fits standard racks but leaves no room for additional full-height expansion cards beyond the installed quad-port 1 GbE and 10 GbE SFP+ daughter card. Dual 1600 W platinum power supplies deliver redundancy, yet the fixed 48 DIMM slots and four-socket maximum mean memory and CPU scaling stop at 6 TB and four processors respectively.

Questions about this item

How much memory can I add to the 48 DDR4 slots before hitting the 6TB limit?

The R940 supports up to 6TB total across 48 DDR4 slots; 128GB is installed now as eight 16GB modules.

Will the PERC H730P controller become a bottleneck when all eight 600GB 10K SAS drives are under sustained write load?

The H730P provides 12Gb/s SAS connectivity and 2GB cache with battery backup, matching the 12Gb/s drive interface for sustained throughput.

How loud and hot does the 3U chassis get when both 1600W platinum PSUs and four Xeon Gold 5118 CPUs run 24/7?

Redundant 1600W platinum supplies and 3U airflow are built for continuous operation; fan speed scales with CPU and inlet temperature.
