2U 2S Server; Maximize NVMe Bandwidth
This 2U PowerEdge R7525 configuration supports eight NVMe drives and sixteen
SATA/SAS drives. The first four NVMe drives are directly connected to CPU2 and the
last four NVMe drives are directly connected to CPU1. Customers supporting workloads
that demand maximum NVMe and storage performance will need maximum bandwidth
provided by this configuration to drive the best throughput (GB/s) performance connect
to the devices.
