Can Fibre Channel fabrics handle quality of service, i.e. prioritized storage traffic and bandwidth guarantees according to given rules?
No, there is no QoS in Fibre Channel. Theoretically, Class 1 gives it to you but there are no Class 1 switches that I know of (Inrange maybe). Even so, there are no Class 1 HBAs.
