Synchronous SnapMirror is a SnapMirror feature in which the data on one storage system is replicated on another storage system at, or near, the same time it is written to the first storage system. Synchronous SnapMirror synchronously replicates data between single storage systems or clustered storage systems situated at remote sites using either an IP or a Fibre Channel connection.
The storage system requires a software license to enable the SnapMirror Sync service.
You are provided with the appropriate license codes when the software is shipped to you or when you are given instructions for obtaining the software over the Internet
