Fabrics are the key to most contemporary installations, and inter-switch links (ISLs) are crucial to scaling a fabric as your SAN grows. @exb Multiple ISLs increase fabric performance With two 2Gb/s ISLs between two switches, aggregate bandwidth is increased to 4GB/s. @exe You'll want to install an ISL between connecting switches when you reach the limits of a single switch and have to enlarge the fabric. Take the example of an e-mail application that started out being deployed on a single FC switch, but has grown so rapidly that it exhausted the available ports on the single switch. On top of that, upper management has decided that because e-mail is another form of corporate communication, the application should now be considered mission critical.
