Four-socket Xeon server for mission-critical

The Dell PowerEdge R940 is a 3U rack server equipped with four Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores and a 3.7 GHz turbo frequency. It ships with 768 GB of DDR4 2666 MHz registered ECC memory across 24 modules. The system targets organisations that need dense compute capacity for databases, virtualisation or real-time analytics in a single chassis.

Redundant 1600 W platinum power supplies

Dual 1600 watt platinum-efficiency power supplies provide full redundancy and hot-swap replacement without downtime. The 3U form factor houses eight 2.5-inch drive bays populated with 400 GB SATA SSDs, while the chassis airflow path cools all four sockets and memory population under typical data-centre inlet temperatures.

PERC H730P RAID, quad-port networking

The onboard PERC H730P controller with 2 GB cache supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through modes for the installed SSDs. A quad-port network daughter card adds two 1 GbE and two 10 Gb SFP+ connections. iDRAC9 Enterprise enables comprehensive remote management, firmware updates and hardware monitoring over a dedicated interface. Ready rails and a front bezel are included for immediate rack installation.

Questions about this item

How do I install the 4 Xeon Gold 6148 processors into the LGA 3647 sockets, and what step is often missed?

Align each CPU with the socket keying, lower the load plate, and torque the retention screws in the labelled sequence; the step often missed is applying the supplied thermal grease evenly before seating the heat-sink assembly.

Which components will need replacement first during the server's lifespan?

The 8 x 400 GB SATA SSDs and the PERC H730P controller's backup battery are the primary wear items; plan to monitor SSD endurance and replace the battery when iDRAC 9 reports degraded capacity.

What thermal or power limit appears first when all 4 CPUs run at 3.7 GHz turbo under sustained load?

The dual 1600 W platinum power supplies and the 3U chassis airflow set the practical ceiling; sustained all-core turbo will hit the platform power budget before individual CPU thermal throttling activates.
