Symantec products can provide the ultimate levels of availability in the IBM virtual environment. In a logical partition (LPAR) environment, you can choose a different combination of Symantec High Availability solutions: ApplicationHA and Symantec Cluster Server (VCS).

ApplicationHA by itself provides application monitoring and restart capabilities while providing ultimate visibility and manageability through Veritas Operations Manager. When ApplicationHA is adopted together with Symantec Cluster Server in the host, the two solutions work together to ensure that the applications are monitored and restarted if needed, and virtual machines are restarted if application restarts are not effective. These two solutions work together to provide the ultimate level of availability in your LPAR environment.

If your virtual environment requires the same level of application availability provided by a VCS cluster in a physical environment, you can choose to adopt Symantec Cluster Server in the virtual machines. In this configuration, your application enjoys fast failover capability in a VCS cluster in the virtual machines.

Table: Comparison of availability options

Required availability level	Recommended solution
Application monitoring and failover to standby node in cluster	VCS cluster in the LPARs See the Symantec Cluster Server documentation.
Application monitoring and restart	ApplicationHA in the LPAR See How ApplicationHA is deployed in an IBM PowerVM environment.
Virtual machine monitoring and restart	VCS cluster in the management LPAR monitoring the virtual machines as a resource See About virtual machine (logical partition) availability.
Combined application and virtual machine availability	ApplicationHA in the LPAR and VCS cluster in the management LPAR See How ApplicationHA is deployed in an IBM PowerVM environment. See About virtual machine (logical partition) availability.

Note:

You can also use the cluster functionality of Symantec Storage Foundation HA or Symantec Storage Foundation Cluster File System HA if you need storage management capabilities in addition to application availability for your LPAR environment.
