Four-socket 3U server for mission-critical workloads

The Dell PowerEdge R940 fits four Intel Xeon Platinum 8160 processors, each with 24 cores at 2.1 GHz, into a 3U rack chassis. With 256 GB of DDR4 registered ECC memory across 48 slots and a PERC H730P controller, it targets databases, virtualization and real-time analytics that demand high core counts and large memory capacity.

Hot-swap bays and redundant power for continuous

Eight 2.5-inch drive bays support SATA and SAS devices; two 800 GB SATA SSDs are installed. The H730P controller provides RAID 0, 1, 5, 6, 10, 50, 60 and pass-through with a battery-backed cache. Dual 1600 W platinum power supplies and a quad-port network daughter card with two 1 GbE and two 10 Gb SFP+ links are hot-swappable, while iDRAC 9 Enterprise enables remote management.

Platinum power supplies and multi-socket thermals

Redundant 1600 W platinum-efficiency units share the load across four 24-core CPUs and 256 GB of DDR4, keeping per-supply utilisation moderate during typical database or virtualization runs. The 3U form factor allows larger heatsinks and directed airflow, so fan speeds remain lower than in denser 1U or 2U designs. iDRAC 9 Enterprise monitors inlet temperature, power draw and fan health in real time, letting operators adjust policies before thermal thresholds are reached.

Questions about this item

What RAID levels does the PERC H730P controller support?

The PERC H730P supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode.

What rack space and rails are required to mount this 3U server?

It occupies 3U of rack height and ships with ready rails for standard square-hole or threaded cabinets.

How are the four processors and 256 GB of DDR4 memory installed, and what mistake should I avoid?

All four Xeon 8160 CPUs and eight 32 GB DDR4 modules are factory-installed; do not mix registered ECC with unbuffered memory when expanding.
