When implemented correctly, high-availability servers and systems add much-needed redundancy and data protection to a virtual environment.

The importance of high-availability technologies has increased with the popularity of server virtualization. As organizations virtualize more workloads and increase consolidation ratios, high-availability servers and systems protect virtual machines (VMs) against extended periods of downtime.

There are a variety of ways to architect high availability into a virtual infrastructure, including failover clustering, load balancing and fault-tolerance technologies. When evaluating these options, IT pros must also account for their existing hardware, software and budgetary constraints.

The following resources will show you how high-availability servers and systems function in a virtual infrastructure, how to choose the best options for your data center as well as helpful hints and best practices for deploying efficient high-availability systems.
