Explanation

A mesh topology may be one of the two types: full mesh or partial mesh. In a full mesh, every switch is connected to every other switch in the topology . A full mesh topology may be appropriate when the number of switches involved is small. A typical deployment would involve up to four switches or directors, with each of them servicing highly localized host- tostorage traffic. In a full mesh topology, a maximum of one ISL or hop is required for host- tostorage traffic. However, with the increase in the number of switches, the number of switch ports used for ISL also increases. This reduces the available switch ports for node connectivity. In a partial mesh topology, several hops or ISLs may be required for the traffic to reach its destination. Partial mesh offers more scalability than full mesh topology. However, without proper placement of host and storage devices, traffic management in a partial mesh fabric might be complicated and ISLs could become overloaded due to excessive traffic aggregation.
