A network design engineer is designing a new storage area network that combines multiple separate legacy SAN environments within a data center. Which technology isolates events within one of the SAN e

FCIP tunnels extend a SAN over an IP WAN for geographically dispersed connectivity and do not provide isolation between separate SAN environments on the same data center fabric.

NPIV allows a single physical HBA port to register multiple virtual N_Port identities for server virtualization use cases and does not isolate distinct SAN environments from one another.

NPV reduces fabric domain ID consumption by proxying edge switch ports through a core switch, but does not create isolation boundaries between separate SAN environments.

VSANs segment a single physical Fibre Channel fabric into multiple isolated logical fabrics, ensuring that events such as RSCNs, domain ID recalculations, and fabric reconfigurations in one VSAN do not propagate to other VSANs. Each VSAN maintains its own zone set, name server, and fabric services, providing the same isolation as physically separate SANs. This makes VSANs the correct technology for merging multiple legacy SAN environments while preventing cross-environment disruption.
