Veritas InfoScale products support various configurations in the VIOS-based virtual environment. Veritas InfoScale products 7.3 is certified on AIX.

Veritas InfoScale products provide the following functionality for VIO:

Storage visibility
Storage management
Replication support
High availability
Disaster recovery

The configurations profiled in the table below are the minimum required to achieve the storage and availability objectives listed. You can mix and match the use of SFHA Solutions products as needed to achieve the desired level of storage visibility, management, replication support, availability, and cluster failover for the Virtual I/O server (VIOS) and logical partitions (LPARS).
