NVMe backplane combinations
Follow the instructions in this section to learn how do cable routing for pure NVMe backplanes.
Note
- See Connecting cables to the processor and memory expansion tray to perform the procedure properly while connecting PCIe cables to the processor and memory expansion tray.
- See Connecting cables to the NVMe switch cards to perform the procedure properly while connecting PCIe cables to the PCIe switch cards.
See the following sections for cable routing combinations with only NVMe drive backplanes.
