High Availability - American Megatrends StorTrends 1100-P User Manual

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 2.6 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.
