Chapter 8. MetroCluster
This chapter describes the MetroCluster feature. This integrated, high-availability, business
continuance solution allows clustering of two N6000, or N7000 storage controllers at
distances up to 100 kilometers.
The primary goal of MetroCluster is to provide mission-critical applications with redundant
storage services in case of site-specific disasters. By synchronously mirroring data between
two sites, it tolerates site-specific disasters with minimal interruption to applications and no
data loss.
This chapter includes the following sections:
򐂰 Overview of MetroCluster
򐂰 Business continuity solutions
򐂰 Stretch MetroCluster
򐂰 Fabric Attached MetroCluster
򐂰 Synchronous mirroring with SyncMirror
򐂰 MetroCluster zoning and TI zones
򐂰 Failure scenarios
