Dell PowerEdge R940 3U Server

This Dell PowerEdge R940 is a 3U rack server equipped with four Intel Xeon Gold 5120 processors running at 2.2 GHz with 14 cores each. It includes 64 GB of DDR4 registered ECC memory across 48 available slots and a PERC H730P storage controller managing eight 600 GB 10K SAS drives.

Suits compute-heavy workloads needing four-socket

Buyers who need more than 64 GB of memory or more than eight drive bays should look elsewhere. The system is limited to four processors and 48 DIMM slots, and the 2.5-inch bay count is fixed at eight.

Four-socket Xeon Gold 5120 configuration

The decisive specification is the four-socket Intel Xeon Gold 5120 configuration with 14 cores per processor at 2.2 GHz. This defines the threading capacity and memory-channel layout that determines whether the server matches the workload.

Questions about this item

How do I install the Dell PERC H730P controller and the 8x 600GB SAS drives in the 3U chassis, and what step is often missed?

Slide the controller into the dedicated internal slot, connect the SAS cables to the backplane, insert all eight 2.5-inch drives into the front bays, then use the iDRAC9 Enterprise interface to initialise the virtual disks — skipping the array creation step leaves the drives invisible to the OS.

Which components in this R940 will need replacement first during long-term operation?

The eight 600GB 10K SAS drives and the H730P controller battery are the primary wear items; the 1600W platinum power supplies and system fans are hot-swap redundant, so they can be swapped without downtime when alerts appear.

What limit appears first when all four Xeon Gold 5120 processors run sustained workloads in this 3U server?

The 3U form factor constrains airflow, so thermal headroom becomes the bottleneck before the 6TB memory ceiling or the 12Gb/s SAS bandwidth is reached.
