Figure 24. The sample environment

Configuring for high availability

After virtualizing physical servers that had been dedicated to particular applications and

consolidating the resulting VMs on a XenServer host, you must ensure that the host will be able to run

these VMs. Designing for high availability means that the components of this environment – from

servers to storage to infrastructure – must be able to fail without impacting the delivery of associated

applications or services.

For example, HP StorageWorks P4000 SANs offer the following features that can increase

availability and avoid SPOFs:

 Hardware-based RAID for the storage node

 Multiple network interfaces bonded together
