About application availability options
If your KVM environment requires the same level of application availability provided by a VCS cluster in a physical environment, you can choose to adopt 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 | Supported virtualization option |
---|---|---|
Virtual machine monitoring and restart | VCS cluster in the host monitoring the virtual machines as a resource | Red Hat Enterprise Linux (RHEL) KVM SUSE Linux Enterprise Server (SLES) KVM |
Application failover to standby node in cluster | VCS cluster in the virtual machines | Red Hat Enterprise Linux (RHEL) KVM SUSE Linux Enterprise Server (SLES) KVM Microsoft Hyper-V Oracle Virtual Machine (OVM) |
Note:
For application high availability and failover capabilities the application data must be on the shared storage accessible to all the nodes of the VCS cluster.
For setup information for VCS:
See Installing and configuring VCS in a kernel-based virtual machine (KVM) environment.
Note:
You can also use the cluster functionality of Storage Foundation HA or Storage Foundation Cluster File System HA if you need storage management capabilities in addition to application availability for your KVM environment.
