Hello

 

Ask away. On a basic level, it uses True Copy like technology to mirror writes between arrays before the acknowledgement is sent back to the host. Reads are services from either side. A great place to start regarding how it works, would be the Hitachi Vantara Knowledgebase:

The Overview page has some of the most common use cases and failure scenarios.
