Veritas Storage Foundation for Windows

Storage Foundation for Windows supports clustered environment set up under the Microsoft Cluster Service (MSCS) software for up to eight nodes under Windows Server 2003.

With Storage Foundation for Windows, you can create mirrored, RAID-5 and other advanced dynamic volumes on MSCS clustered storage thus providing minimum downtime for applications.

The Dynamic Multipathing (DMP)Option adds fault tolerance to disk storage by making use of multiple paths between a computer and individual disks in an attached storage system. Disk transfers that would have failed because of a path failure are automatically rerouted to an alternate path. With the DMP Option, you can configure, manage and obtain status information about these multiple paths.

DMP also improves performance by allowing load balancing between the multiple paths.

Support for Microsoft Multipath IO (MPIO.

The Storage Foundation for Windows Enterprise Option combines support for FlashSnap, MSCS and DMP into one option.

Veritas FlashSnap allows you to create independently addressable point-in-time snapshots that are copies of mirrors of the volumes on your server. These snapshots can be easily moved to another server for backup or other purposes such as testing or data mining. These activities can be performed without affecting the normal functions of mission-critical servers.

The snapshots may also be kept on the same server for rapid recovery from data corruption issues. You may choose to recovery to the point of the last snapshot or to the point-in-time immediately before the failure. Even when FlashSnap is performed on the same server, its very efficient mirror breakoff and join process is much faster and takes less CPU availability than other mirror breakoff procedures that use ordinary mirroring.

Reliably, efficiently and consistently mirrors data to remote locations over any IP network for maximum business continuity.
