Benefits of active/active configurations
Active/active configurations provide fault tolerance and the ability to perform nondisruptive upgrades and maintenance.
Configuring storage systems in an active/active configuration provides the following benefits:
•
Fault tolerance
When one node fails or becomes impaired a takeover occurs, and the partner node continues to serve the failed node’s data.
•
Nondisruptive software upgrades
When you halt one node and allow takeover, the partner node continues to serve data for the halted node while you upgrade the node you halted.
•
Nondisruptive hardware maintenance
When you halt one node and allow takeover, the partner node continues to serve data for the halted node while you replace or repair hardware in the node you halted.
