Connecting enclosures

 All the EXP ports on the storage system can connect only to the PRI ports. An incorrect connection will cause
a service interruption.
 For a storage system with two or more disk enclosures, set up multiple loops based on the number of
expansion ports on the controller enclosure, and evenly allocate those disk enclosures to the loops.
 Connect disk enclosures in one loop over two separate links for optimal network reliability.
