Supported configurations for Virtual I/O servers (VIOS) on AIX
Veritas InfoScale products support various configurations in the VIOS-based virtual environment. Veritas InfoScale products 7.4.1 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).
Table: Veritas InfoScale features in a VIO environment
Objective | Recommended Veritas InfoScale products configuration |
---|---|
Storage visibility for LPARs | Dynamic Multi-Pathing (DMP) in the LPAR |
Storage visibility for the VIOS | DMP in the VIOS |
Storage management features and replication support for LPARs | Veritas InfoScale products in the LPARs See Veritas InfoScale products in the logical partition (LPAR). |
Advanced storage management features and replication support for LPAR | Storage Foundation Cluster File System High Availability (SFCFSHA) in the LPARs See Storage Foundation Cluster File System High Availability in the logical partition (LPAR). |
End-to-end storage visibility in the VIOS and LPARs | DMP in the VIOS and LPARs See Dynamic Multi-Pathing in the Virtual I/O server (VIOS) and logical partition (LPAR). |
Storage management features and replication support in the LPARs and storage visibility in in the VIOS | DMP in the VIOS and SF in the LPARs |
Virtual machine monitoring and availability for managed LPARs | Cluster Server (VCS) in the management LPARs |
Application failover for LPARs | VCS in the LPARs |
Application failover across LPARs and physical hosts | VCS in a cluster across LPARs and AIX physical host machines See Cluster Server in a cluster across logical partitions (LPARs) and physical machines. |
Each configuration has specific advantages and limitations.
