Introduction

  • This section describes the PowerStore native asynchronous (PowerStoreOS 3.0 and later) and synchronous replication feature (PowerStoreOS 4.0 and later) which allows users to create replication sessions for block and file storage resources between PowerStore systems. Synchronous replication for Metro is covered in the white paper Dell PowerStore: Metro Volume. Supported storage resources for native replication are volumes, volume groups, thin clones, and NAS servers which includes the underlaying file systems. The replication itself uses iSCSI or the optimized Dell proprietary TCP-based replication protocol (PowerStoreOS 3.0 and later) through Ethernet (LAN) connections. All configuration and management operations in this section are shown in PowerStore Manager, but you can also use the PowerStore CLI and REST API. The following subsections describe these topics:

    • Licensing requirements for the native replication features
    • How the native asynchronous replication feature works
    • Enhancements to asynchronous replication to get synchronous replication
    • Supported configurations
    • PowerStore Manager configuration and management
