Asynchronous Replication (Formerly FlashRecover) Configuration and Best Practice Guides

Asynchronous Replication Configuration and Best Practices

Asynchronous Replication Configuration and Best Practices are now divided into two guides based on the Purity version the FlashArray is running:

FlashArray Asynchronous replication (formerly FlashRecover replication) is a snapshot-based replication solution that leverages space-efficient snapshots to replicate point-in-time consistent copies of one or more FlashArray volumes. FlashArray asynchronous replication combines snapshots and replication into a single feature allowing you to create multiple recovery points on the replication target FlashArray.

Each of the linked guides provides an end-to-end walk-through for configuring FlashArray Asynchronous replication and performing data recovery tasks such as failover and failback. In addition, best practices and important considerations to be aware of are also provided. 

Purity version replication interoperability 

Replication is supported in both directions between different minor versions of Purity with some limitations:

  • Starting with Purity 4.8, replicating to a 4.8 target array requires that the source array is running Purity 4.7.5 or newer.
  • Replication is not possible between Purity 4.8 and versions of Purity older (lower) than 4.7.5.
  • Purity version 5.0.x and higher are also backward compatible subject to the Purity Requirements and Interoperability Matrix. For the most up-to-date information about Purity replication interoperability, please see: Purity Replication Requirements and Interoperability Matrix
