How many ISL ports are required between the cluster interconnect switches when using CN1610 switches?

Two ISL ports do not provide adequate bandwidth or redundancy for a critical cluster interconnect in a standard NetApp configuration.

For NetApp clusters utilizing CN1610 switches, a minimum of four Inter-Switch Link (ISL) ports are required between the two cluster interconnect switches. These four ISL connections provide sufficient bandwidth and redundancy for the critical communication between cluster nodes across the switches.

Six ISL ports are more than the minimum recommended requirement for standard CN1610 cluster interconnect configurations.

Eight ISL ports represent an excessive number for the minimum ISL requirement and are not typically used for standard CN1610 cluster interconnects.

Inter-Switch Links are absolutely necessary to connect cluster interconnect switches and facilitate communication between cluster nodes.
