Mission-critical 3U server for four-socket density

The Dell PowerEdge R940 packs four Intel Xeon Platinum 8160 processors into a 3U rack chassis. Each CPU delivers 24 cores at 2.1 GHz with a 3.7 GHz turbo frequency. The system ships with 256 GB of DDR4 2666 MHz registered ECC memory across 48 slots. It targets organisations that need maximum compute density for databases, virtualisation or real-time analytics in a single rack unit.

Dual 1600 W platinum supplies handle peak loads

Redundant hot-swap 1600 W power supplies with platinum efficiency feed the four-socket configuration. The 3U form factor allows adequate airflow for the 4 x 24-core processors and memory population. iDRAC 9 Enterprise provides remote thermal monitoring and power capping without requiring physical access. The platform is designed for continuous operation in cooled data-centre environments.

PERC H730P RAID and quad-port networking included

A Dell PERC H730P 2 GB controller supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through for the two installed 400 GB SATA SSDs and up to eight 2.5-inch bays. An Intel X520/I350 daughter card adds two 1 GbE and two 10 Gb SFP+ ports for flexible fabric connectivity. ReadyRails and a front bezel ship with the unit for immediate rack integration.

Questions about this item

How do I install the four Xeon 8160 processors into the LGA 3647 sockets without bending pins?

Align the triangle marker on each Xeon 8160 with the socket corner, lower the processor vertically without force, close the load plate and torque the retention screws in a cross pattern to the specified value.

What maintenance will the PERC H730P 2 GB controller battery need later?

The controller battery backs the write cache; plan to replace it every three to five years or when iDRAC 9 Enterprise reports a degradation alert.

Which limit appears first when the 2 x 400 GB SATA SSDs run sustained write workloads?

The drives hit their steady-state write throughput ceiling before the 12 Gb/s SAS/SATA controller or the 2666 MHz DDR4 memory bandwidth becomes saturated.
