When you connect external storage systems to a port, information on those storage systems can be viewed from client computers. Multiple external storage systems from different vendors can be connected to the same port. Even if a port connected to external storage systems is in use, you can connect additional external storage systems.
Note: The port with the NVMe operation mode cannot be used for an external path.
Make sure the external system ports you use have enough capacity for the read/write workload planned for the external volumes. See the discussion in External paths for more information. Refer to the documentation for the external system for full information.
