Maximum number of concurrent replication operations

Hi,

IHAC is using FAS8020A to store NFS data. Now they want to use sync/semi-sync snapmirror to protect the data.

They have 18 volumes on each controller. The max number is 32 for FAS8020.

The question is 32 is for one controller, after failover, the max number is 32 or 64 on the survival controller?

If it is 32, can we have some volumes as sync/semi-sync, and others as async snapmirror?

When using semi-sync and async snapmirror, what's the max concurrent number?

Thanks,

Jeff Cai

You cannot create a synchronous SnapMirror relationship between FlexVol volumes within the same system or within the same HA pair
