1.Configuration with minimum number of cascading paths
Blade Enclosure #1
Blade Enclosure #2 | Blade Enclosure #3 |
If a failure occurs on the cascading path between the FC Switch Modules, a
Fabric reconstruction occurs. Influence to I/O operations may occur not only between the cascading FC Switch Modules but within each FC Switch Module (each Blade Enclosure).
2.Two paths configuration between the FC Switch Modules
Blade Enclosure #1
Blade Enclosure #2 | Blade Enclosure #3 |
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.
