High-Availability solution for ensuring data availability in business-critical environments.
Continuous Data Availability
Active-Active Controller delivers a robust and highly available data service for business-critical environments. NetApp Active-Active Controller is installed on a pair of NetApp storage controllers, and during normal operation each controller services its own workload while monitoring the health of its "partner" controller. If one of the controllers fails or is taken offline, the second controller can assume its workload and continue processing. The transfer of data service is transparent to end users and applications, and the data service is quickly resumed with no detectable interruption to business operation. The data service of the takeover storage system is never impacted and is fully available during the entire failover operation. The entire failover process is automatic, with no manual intervention required at any point.
NetApp Active-Active Controller can benefit any enterprise, workgroup, or e-commerce application that has stringent uptime requirements. Clustered Failover administration tasks are simple, intuitive, and easy to use, minimizing management overhead and reducing operator error. Collectively, they further enhance the total availability of the overall environment.
| Features | Benefits |
| Automatic failover with notification | Provides continuous data availability for an unavailable storage controller and notifies administrator of failover. |
| Manual failover and giveback | Enables planned maintenance on a storage controller without impacting data availability; gives administrators total control over determining when to restore a clustered storage system to its normal state. |
| Transparent failover | End users are not impacted by a failover; clients continue to access data the same way after a failover. |
| Active/Active configuration | Both clustered storage systems are doing useful work; no idle resources are required for cluster operation. |
| Straight-forward design and implementation | Administrators can install and configure clustered storage systems in less than 30 minutes; minimal ongoing maintenance is required. |
| Long-distance cluster | Administrators have great flexibility with the physical location of clustered storage systems. |
