8 x 2.5'' NVMe drives with two 4 x 2.5'' NVMe backplanes (one processor and liquid cooling)
Use this section to understand the cable routing for eight NVMe drives for liquid cooling (NeptAir module) configuration with two 4 x 2.5'' NVMe backplanes and one processor installed.
Cable routing for onboard configuration
The following table shows the mapping relationship between backplane connectors and processor board connectors for onboard configuration.
The following figure illustrates the cable routing for the onboard configuration of 8 x 2.5-inch front NVMe drive bays. Connections between connectors: 1 ↔ 1, 2 ↔ 2, 3 ↔ 3, ... n ↔ n
