ONTAP 9.5 SnapMirror Synchronous SM-S Configuration

SnapMirror Synchronous (SM-S):

Finally SnapMirror Synchronous comes to ONTAP to  meet regulatory and industry mandatory requirements.

SnapMirror Synchronous allows user to replicate volume level – data, cross a Wide Area Network connection with zero Recovery Point Objective (RPO) and very low Recovery Time Objective (RTO). This helps to address regulatory and industry mandated needs for synchronous replication. SnapMirror Synchronous will have two different modes available in the initial release.

StrictSync

•     Read and write to primary denied, if any failure in replication at secondary

Sync

•      Read and write to primary will continue without any disruption

In the initial release of SnapMirror Synchronous, NFSv3, iSCSI and FCP will be supported. Licensing will be capacity-based, in addition to the base SnapMirror® license.
