8i RAID/HBA adapter + Two retimer cards

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

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