4 x 2.5'' NVMe backplane
Use this section to understand the NVMe backplane cable routing for server model with four 2.5-inch front drives and two processors.
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 4 x 2.5-inch front NVMe drive bays. Connections between connectors: 1 ↔ 1, 2 ↔ 2, 3 ↔ 3, ... n ↔ n
