Technical White Paper: ApplicationHA
http://www.vmware.com/files/pdf/techpaper/vsp4-virtualize-biz-critical-apps.pdf
Symantec ApplicationHA provides monitoring capabilities for applications running inside virtual machines hosted on ESX or ESXi hosts managed by aVMwarevCenter Server. Symantec ApplicationHA adds a layer of application awareness to the core High Availability functionality offered by VMware virtualization technology.
Symantec ApplicationHA is based on Veritas™Cluster Server (VCS) and internally uses similar concepts such as agents, resources, and service groups. However, it does not include the high availability cluster components such as the Global Atomic Broadcast (GAB) and Low Latency Transport (LLT). Symantec ApplicationHA has a lightweight server footprint that allows faster installation and configuration. Key benefits include:
■ Out of box integration with VMwareHA and VMware vCenter Server
■ Full visibility and control over applications with the ability to start, stop, and monitor applications running inside virtual machines
■ Standardized way to manage applications using a single interface that is integrated with VMware vSphere Client
■ Specialized Application Maintenance mode, in which ApplicationHA allows you to intentionally take an application out of its purview for maintenance or troubleshooting
