2.
Two paths configuration between the FC Switch Modules
By making cascade connection between FC Switch Modules to two paths,
even if a failure occurs on one cascade path, no influence to I/O operation
occur because I/O operation is succeeded by redundant path and no Fabric
reconstruction occurs.
3.
Alternate path between the FC Switch Modules
By making cascade connection among all four FC Switch Modules, even if a
failure occurs on one cascade path, no influence to I/O operation occur
because communication between FC Switch Modules can be succeeded by
the alternate path and no Fabric reconstruction occur.
