Cascading two 8G FC Switch (Blade Enclosure)
One path configuration between the 8G FC Switch
1.
Blade Enclosure #1
IMPORTANT:
If a failure occurs on the cascading path between the 8G FC Switch, a Fabric
reconstruction occurs. Influence to I/O operations may occur not only between the
cascading 8G FC Switch but within each 8G FC Switch (each Blade Enclosure).
Two paths configuration between the 8G FC Switch
2.
Blade Enclosure #1
IMPORTANT:
By making cascade connection between 8G FC Switch 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.
