iStorage Server supports clusters under Windows operating systems
High-availability clusters (also known as HA Clusters or Failover Clusters) are computer clusters that are implemented primarily for the purpose of providing high availability of services which the cluster provides. They operate by having redundant computers or nodes which are then used to provide service when system components fail. Normally, if a server with a particular application crashes, the application will be unavailable until someone fixes the crashed server. HA clustering remedies this situation by detecting hardware/software faults, and immediately restarting the application on another system without requiring administrative intervention, a process known as Failover. As part of this process, clustering software may configure the node before starting the application on it. For example, appropriate file systems may need to be imported and mounted, network hardware may have to be configured, and some supporting applications may need to be running as well.
Main benefits of clustering are:

Main benefits of clustering are:
- Reduced single points of failure through Exchange Virtual Server (EVS) failover functionality.
- Ability to perform maintenance and upgrades with limited downtime.
- Ability to easily scale up your cluster to a maximum of seven active EVSs.
