Introduction

Introduction

  • PowerScale SyncIQ provides asynchronous data replication for disaster recovery and business continuity, allowing failover and failback between clusters. It is configurable for either complete cluster replication or only for specific directories. Within a PowerScale cluster, all nodes can participate in replication. After an initial SyncIQ replication, only changed data blocks are copied minimizing network bandwidth and resource utilization on clusters.

    This section provides considerations for SyncIQ pertaining to external network connectivity. For more information about SyncIQ, see the PowerScale SyncIQ: Architecture, Configuration, and Considerations white paper.
