HA Storage Clusters are used to provide critical shared data on a network, and as system and data drives for physical and virtual production servers and critical workstations.
They operate by using redundant servers that provide continued service even when individual system components or network elements fail.
Without clustering, if a storage server is down, the data and all related applications and services will be unavailable until the server is back online.
HA Clustering remedies this situation by detecting hardware and software faults, and immediately sending storage requests to the other server in the cluster without requiring administrative intervention.
This benefit is not only for the failures and crashes that will inevitably happen, but also for planned maintenance. A server in the cluster may be taken offline for maintenance and brought back online without interrupting your users or customers.
