Automatic failover with notification - designed to support data availability for an unavailable filer and notify an administrator of failover
Manual failover and giveback - designed to enable planned maintenance on a filer while avoiding impact to data availability; administrators can control when to restore a clustered filer to its normal state
Non-impacting failover - designed to avoid impact of a failover to end users so they can continue to access data in the same way after a failover
The challenge: delivering highly available data service
In today's competitive environment, data is the key asset of many businesses, and supporting high data availability and accessibility is essential. Loss of data service could lead to lost productivity, revenue, and even customer loyalty. Organizations with a data availability strategy that relies on a single hardware device risk losing data access if that device goes offline.
The solution: IBM TotalStorage N series with Clustered Failover
IBM TotalStorage N series with Clustered Failover is designed to provide a robust and highly available data service for business-critical environments. Installed on a pair of N series filers, Clustered Failover can help improve data availability by transferring the data service of an unavailable filer to the other filer in the cluster. Often, the transfer of data service is without impact to end users and applications. It is designed to allow the data service to quickly resume while avoiding detectable interruption to business operation.
IBM TotalStorage N series with Clustered Failover 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, helping to minimize management overhead and reduce operator error. Collectively, they can help further enhance the total availability of the overall environment.
