Brocade ISL Trunking - license

Trunking is a feature that enables traffic to be optimally shared across available inter-switch links (ISLs) while preserving in-order delivery. A trunk group logically joins two, three, or four ISLs into one logical ISL. Use of trunking can minimize or eliminate congestion in the SAN because trunking optimizes ISL utilization. Additionally, the use of trunking minimizes the effort of managing a SAN since ISLs are now managed as a group instead of individually.
