4S 3U NVMe Configuration
This 3U PowerEdge R940 configuration supports twelve NVMe drives and twelve
SATA/SAS drives. The NVMe drives are connected directly to CPU3 and CPU4 through
I/O slots and the SATA/SAS drives are connected to the MB PERC. This configuration
must be used for an R940 populated w/ 4 sockets. There are additional I/O slots
available on CPU3 and CPU4 for network adapters to be on the same CPU complex as
the NVMe.
