Performance 4U Server; Maximize NVMe Capacity
This 4U PowerEdge R940xa configuration supports four NVMe drives and twenty
SATA/SAS drives. The NVMe drives are connected directly to CPU3 and CPU4 and the
SATA/SAS drives are connected to the MB PERC through I/O slot 4. This configuration
maximizes NVMe capacity by installing the maximum number of NVMe drives
supported by the R940xa.
