8i/16i RAID/HBA adapter + retimer card
The following shows the cable connections for the 8 x 2.5-inch SAS/SATA + 8 x 2.5-inch NVMe configuration with one 8i/16i RAID/HBA adapter and one retimer card.
| From | To |
|---|---|
Backplane 1: SAS | 8i/16i* RAID/HBA adapter on PCIe slot 2:
|
Backplane 2: NVMe 0-1, 2-3 | Onboard: PCIe 1, PCIe 2 |
Backplane 2: NVMe 4-5, 6-7 | Retimer card on PCIe slot 1: C0, C1 |
Note
*If a 16i RAID adapter is used, SAS cable 1 has an extra dummy connector (not shown in below illustration) to connect to the other connector of the 16i RAID adapter.
Connections between connectors: 1 ↔ 1, 2 ↔ 2, 3 ↔ 3, ... n ↔ n
