8i RAID/HBA adapter
The following shows the cable connections for the front (16 x 2.5-inch SAS/SATA + 8 x 2.5-inch Gen 4 NVMe) configuration with two 8i RAID/HBA adapters.
To connect the processor interconnection cable when two processors are installed, see Processor interconnection cable routing.
Connections between connectors: 1 ↔ 1, 2 ↔ 2, 3 ↔ 3, ... n ↔ n
