Virtual Connect fabrics 106
To create a proper Virtual Connect fabric, all VC-FC uplinks that are included in the fabric must be connected
to the same physical SAN fabric. If the fabric uplinks are not connected to the same SAN fabric, then the
fabric becomes degraded and a log message indicates that the uplinks are connected to different SAN
switches. The WWN of the principal fabric switch indicates connectivity to the same SAN fabric in Virtual
Connect.
The VC-FC module uses dynamic login distribution to provide the following:
•
Load balancing as new server HBA logins are completed through the uplink port with the least amount
of active logins
•
A failover path if an uplink becomes unusable
