VVR provides several methods to initialize the application data between the primary location and the remote location, such as using the network, using tape backup, and moving disks physically. The volumes on the Primary host must be initially synchronized with the volumes on the Secondary host. You can have up to 32 Secondary hosts in a VVR environment. In the Koenig course for Veritas Volume Manager (Storage Foundation 5.1) administration for Solaris, you learn to integrate, operate, and make the most of Veritas Volume Manager (Storage Foundation), including Veritas Volume Manager (VxVM) and Veritas File System (VxFS), in a Linux environment. The host at the source location on which the application is running is known as the Primary host, and the host at the target location is known as the Secondary host. If a disaster occurs at the source location, you can use the copy of the application data at the remote location and restart the application at the remote location. It provides a consistent copy of application data at the remote locations. VVR replicates the application writes on the volumes at the source location to one or more remote locations across any distance. VVR is available by default with InfoScale Storage and InfoScale Enterprise products.
VVR can replicate existing VxVM configurations, and can be transparently configured while the application is active. VVR benefits from the robustness, ease of use, and high performance of VxVM, and at the same time, adds replication capability to VxVM. VVR is an option of Veritas Volume Manager (VxVM) that works as a fully integrated component of VxVM. Provides high availability storage solutions through. This overcomes the physical limit of the disk. Allows creation of logical volumes spanning over multiple disks. The main features of volume manager are following. Physical objects are direct mappings to physical disks. Veritas Volume Manager is used to manage disk storage spread over an array of disks. VxVM uses two types of objects to perform the storage management.
VVR enables you to maintain a consistent copy of application data at one or more remote locations. Veritas Volume Manager is a storage management application by Symantec, which allows you to manage physical disks as logical devices called volumes.
