Configuration 2: two 8 x 2.5" NVMe front backplanes, one rear drive cage (SAS/SATA), one 8i RAID/HBA adapter

This configuration supports one rear drive cage with the 4 x 2.5-inch SAS/SATA drive backplane.

Note
The RAID/HBA adapter can be installed on riser card 1 (scenario 1) or riser card 2 (scenario 2). The following illustration shows the cable connections for scenario 1. The cable connections are the same for scenario 2.
