Replacing a single FibreBridge 6500N bridge with a single FibreBridge 7500N bridge

No

The FibreBridge 7500N bridge must be configured exactly the same as the FibreBridge 6500N bridge, using a single FC port and attaching to a single stack. The second FC port on the FibreBridge 7500N must not be used.

Consolidating multiple stacks by replacing multiple pairs of FibreBridge 6500N bridges with a single pair of FibreBridge 7500N bridges

Yes

In this case, you take the FibreBridge 6500N bridges out of service and replace them with a single pair of FibreBridge 7500N bridges.Each pair of FibreBridge 7500N or 7600N bridges can support up to four stacks.

At the end of the procedure, both the top and bottom of the stacks must be connected to corresponding ports on the FibreBridge 7500N bridges.

Adding new storage through adding a new pair of FibreBridge 7500N bridges

Yes

You must add storage zones for each of the FC ports of the new bridges.

You must have available ports on the FC switch fabric (in a fabric-attached MetroCluster configuration) or on the storage controllers (in a stretch MetroCluster configuration).Each pair of FibreBridge 7500N or 7600N bridges can support up to four stacks.
