Snapmirror sync on ASA clusters question .

[jagged loom]

Hello folks ; i am wandering if Snapmirror sync is working on an ASA cluster with more than one HA pair .

reference : https://docs.netapp.com/us-en/ontap/data-protection/snapmirror-synchronous-disaster-recovery-basics-concept.html#unsupported-features

Unsupported features

The following features are not supported with Synchronous SnapMirror relationships:

Consistency groups
DP_Optimized (DPO) systems
FlexGroup volumes
FlexCache volumes
Global throttling
In a fan-out configuration, only one relationship can be a SnapMirror Synchronous relationship; all the other relationships from the source volume must be asynchronous SnapMirror relationships.
LUN move
MetroCluster configurations
Mixed SAN and NVMe access
LUNs and NVMe namespaces are not supported on the same volume or SVM.
SnapCenter
SnapLock volumes
Tamperproof Snapshot copies
Tape backup or restore using dump and SMTape on the destination volume
Throughput floor (QoS Min) for source volumes
Volume SnapRestore
VVol

SnapMirror Sync: yes. SnapMirror active sync will not work (yet?)

i did found for normal ontap systems : Advanced SM-S topics
Deploying an intra-cluster SM-S deployment
Starting with ONTAP 9.14.1, NetApp has qualified SM-S for replication between two volumes within the
same cluster. These volumes may be in the same SVM or two different SVMs within the same cluster.
These volumes can be hosted on different HA pairs or the same HA pair.
Hosting the source and destination SM-S volumes will not exhibit the same level of availability that
hosting the source and destination volumes on different clusters, in different locations would provide due
to reducing the impact of redundant hardware provided by different clusters. To minimize the impact on
availability when implementing an intra-cluster SM-S deployment, the following items are recommended:
• If possible, place the source and destination volumes on different HA pairs to enhance HA.

but this was not for ASA

yes i notice that SM-BC renamed active sync is on HA only so far and possible expanded on a further release ( from a previous thread opened ) .
