Onboard connectors + 8i RAID/HBA adapter
Front + rear backplanes: 12 x 3.5" SAS/SATA + 4 x 3.5"/4 x 2.5" SAS/SATA
| From | To |
|---|---|
Backplane 1: SAS 0, SAS 1 | Onboard: SATA 0, SATA 1 |
Backplane 1: SAS 2 | Onboard: SATA 2 |
Backplane 4: SAS | 8i RAID/HBA1: C0C1 (Gen 3) or C0 (Gen 4) |
Backplane 4: PWR | Riser 1: PWR1, PWR2 |
Note
For a 4 x 3.5-inch SAS/SATA rear backplane, the 8i adapter1 is installed on PCIe slot 3.
For a 4 x 2.5-inch SAS/SATA rear backplane, the 8i adapter1 is installed on PCIe slot 2.
Below illustration uses the 4 x 3.5-inch SAS/SATA rear backplane as an example for cable routing. Cable routing for the 4 x 2.5-inch SAS/SATA rear backplane is similar.
Connections between connectors: 1 ↔ 1, 2 ↔ 2, 3 ↔ 3, ... n ↔ n
