Vixel hub provides zoning

Last month, Vixel introduced the model 2100 Zoning Managed Hub, which includes zoning capability for up to four independent Fibre Channel loops. With zoning, which is common with switches, any port can be assigned to any loop. Due to the independence of each zone, a loop initialization primitive (LIP) in one zone does not affect applications running in other zones--a common problem with arbitrated loop configurations. Additionally, devices can be added or removed from the hub without disruption.
