Supported configurations for Virtual I/O servers (VIOS) on AIX

InfoScale products support various configurations in the VIOS-based virtual environment and are certified on AIX.

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).
