In my experience, it is one of the most reliable options in SAN switches. Let´s say that the SAN24 is the perfect combination between two great brands (IBM hardware and Brocade´s software). In my experience, Brocade´s software is the best for SAN implementation; easy to use and intuitive in every aspect. Brocade is always updating its IOS (operating system), adding new functionalities to its switches and correcting minor errors. If you add all these things to IBM hardware and support, you can trust that your SAN is going to have near-zero downtime.
