Onboard connectors + 8i RAID/HBA adapter + Retimer card

This topic provides cable routing information for the 8 x 2.5" SAS/SATA + 16 x 2.5" NVMe (Gen 5) configuration with one 8i RAID/HBA adapter and one retimer card when two Platinum series processors are installed.

Connections between connectors: 1 ↔ 1, 2 ↔ 2, 3 ↔ 3, ... n ↔ n
