12 Clustering Implementations for High Availability
Because configuring clustering within the guest OSes in the VMs is no
different than configuring clustering on physical servers that are not
virtualized, this solutions guide does not discuss this model any further. For
more information, refer to the documentation for the guest operating system.
Hyper-V Host Clustering
In this implementation, the Hyper-V host servers are clustered by leveraging
the Windows Failover Clustering feature in Windows Server 2008 x64
editions. Failover Clustering in Windows Server 2008 is a robust and mature
third-generation clustering solution that has been significantly improved in
Windows Server 2008. Leveraging this Failover Clustering feature allows
Hyper-V to offer HA solutions on a wide array of storage solutions including
Direct-Attach SAS, iSCSI, and Fiber Channel storage arrays.
Figure 2-3. Hyper-V Host Clustering
Figure 2-3 illustrates a sample Hyper-V Host Cluster configuration with the
Windows native cluster service running in the Windows Server 2008 x64
Parent Partition. In this scenario, the Failover Clustering service in the parent
partition will manage the VMs as the cluster resources. The VMs running on
either of these servers can be configured as highly available and does not
