Snapshots can be used to ensure data integrity from situations such as rolling disasters, application failures, and even user errors. [. . . ] However, current trends towards 7x24x365 operations severely minimize the available backup window. Because iSN Snapshots can be created very quickly without disrupting the application servers, they can be created at anytime of the day. Then the backup server can mount to the iSN Snapshot rather than the primary volume as the source for the backup, resulting in the elimination of the backup window. iSN Snapshots Dot Hill's iSN offers two kinds of Snapshots - Read-Only and Writeable - enabling non-disruptive creation and removal of snapshots for more efficient data protection, fast recovery and improved capacity utilization. Read-Only Snapshots iSN Read-Only Snapshots are persistent point-in-time copies of volumes that can be created very quickly (in a matter of seconds) without disrupting mission critical applications. Since capacity is only utilized when first changes occur, iSN Snapshots do not consume significant capacity, and can restore corrupted data just as quickly as it is created. Dot Hill's iSN makes available thousands of Read-Only Snapshots, enabling administrators to set policies for creation and removal of Snapshots automatically on a Virtual Replicas: Writeable Snapshots Dot Hill's iSN is one of the only systems currently available that offers massive Virtual Replicas (writeable snapshots). The iSN's Virtual Replicas are non-disruptive and do not con- www. dothi ll. com iSN Snapshots sume significant capacity, providing an excellent solution for development, lab testing (QA), training programs and lengthy batch operations. For example, testing is most effective experimenting with large, mission-critical production databases. However, IT cannot risk disruption to the application itself and it is both cost prohibitive and very time consuming to create a complete copy of the application data. With iSN Virtual Replicas, developers can create a writeable snapshot instantaneously without disrupting the mission critical application, and then mount the snapshot to a separate development server, enabling developers to experiment with the test database, make radical changes, and even delete the entire database without disrupting the primary database. Virtual Replicas can also be used to make Quality Engineering more efficient. Each QA engineer can use a Virtual Replica to test his or her own virtual copy of the new application rather than using a complete copy or sharing one application dataset with the rest of the team. This allows the entire team to be more efficient while saving storage capacity. Similar benefits can be achieved for a training class with each student using a virtual copy of the new application to learn. Using iSN Virtual Replicas saves capacity without affecting the primary application. [. . . ] Dot Hill Systems Corp. , Dot Hill, the DotHill logo, and iSN are trademarks of Dot Hill Systems Corp.
