High Availability
High Availability or HA is a term used in this document to describe the system design
protocol and associated implementation that ensures a certain absolute degree of
operational continuity during a given measurement period.
This Feature allows two StorTrends (version 2.7 and newer) SAN Heads to be grouped as
highly-available cluster nodes for Microsoft initiators. This, together with MPIO DSM
for StorTrends will allow deploying solutions with extreme fault tolerance and total
availability. This solution provides protection against disk failures, path failures and node
failures. In the event of Node failure, the Failover action is automatic and seamless.
When the Failed node comes up, it is detected by the stack and is synchronized quickly to
bring back redundancy to the setup. Synchronization is very efficient and ensures that
only out-of-sync data is resynced.
