In a Huawei OceanStor 18000 the engine, SVP, diskenclosure, and PCIe switch interconnections must be...

The SVP needs to connect multiple engines through two PCI-e switches, and each engine's controller needs to be connected to a PCIe switch to ensure that the link redundancy provides reliability.

When the control plane is connected to the network, when the engine and the PCIe switch are interconnected, the port P0 of the A3 slot and the PCI switch PCI port canbe used pick up.

Huawei OceanStor 18000 can be used to install SAS interface modules and interconnect disk enclosures in slot 0 and slot 5 of the Huawei OceanStor 18000.
