How many initiators per zone should be used to adhere to BEST SAN zoning practices?

Single-initiator zoning is a best practice in Fibre Channel SANs, where each zone includes one host Bus Adapter (HBA) port (initiator) and one or more target storage ports. This approach simplifies troubleshooting, minimizes potential fabric disruptions, and enhances security by limiting device visibility.

Using two initiators in a single zone is not a best practice and can complicate troubleshooting and potentially increase inter-initiator communication issues.

Four initiators in a single zone significantly increases complexity and potential for fabric issues, going against established SAN zoning best practices.

Unlimited initiators per zone would essentially negate the purpose of zoning, leading to an insecure, unmanageable, and highly unstable SAN environment.
