8 Veritas Volume Replicator Release NotesNew featuresNew featuresThis release of Veritas Volume Replicator includes the following features:Replicating volume setsCross-platform data sharingVVR now supports replicating volume sets by including the volume set itself as apart of the RVG. When a volume set is included in an RVG, VVR also ensuresthat the replicated volume set configurations are consistent across the Primaryand Secondary.Veritas Volume Replicator (VVR) is now CDS compliant. VVR uses CDS format tosupport the following functionality:■Migrating data between heterogeneous systems (either on the Primary orthe Secondary) where each system has direct access to the physical devicesused to hold the data. Note that CDS does not support simultaneous use ofdata from more than one platform.Caution: Stop all the applications working on that disk group beforemigrating data between hosts. Failure to do so may result in data loss.■Replicating data between heterogeneous systems. That is, the Primary hostis a different platform from the Secondary host, and each host is able toaccess the data in CDS format.Bunker replicationBunker replication enables VVR to achieve complete Recovery Point Objective(RPO) and limited Recovery Time Objective (RTO) without any major impact onthe application’s performance. Bunker replication uses a bunker site, whichmaintains a copy of only the Primary SRL without having to maintain additionalcopies of the data volumes. This feature combines the advantages ofsynchronous and asynchronous modes of replication.Replication in a shared environmentVVR supports replication in a shared disk group environment. Thisfunctionality of VVR enables you to replicate data volumes that are managed bythe clustering functionality of Veritas Volume Manager. VVR also supports theclustering functionality of Veritas File System and Veritas Storage Foundationfor Oracle RAC.
Veritas Volume Replicator Release Notes 9New featuresVVR enables you to replicate data volumes in a shared disk group environment,for use with parallel applications that use Veritas Cluster Server (VCS) for highavailability. You can replicate data volumes in a shared disk group to a remotesite, for disaster recovery or off-host processing. VVR supports configurationsin which both the Primary and Secondary disk group are shared, or either thePrimary or the Secondary disk group is shared. If the Primary disk group isshared, it is not required that the Secondary disk group must be a shared diskgroup and vice versa. Currently, replication support is limited to 4-node clusterapplications.VEA featuresYou can use VVR VEA to replicate to a bunker, which can then be used fordisaster recovery.Managing VVR using the Web GUIThe VVR Web GUI includes the following new features:■■■Links to volume views enable you to access detailed information about localvolumes in the RDS.New look and feel provides consistency among Veritas Storage Foundationproducts.New role-based administration model enables you to control access toadministrative tasks according to preassigned roles: Storage Administrator,Storage Operator, and Read Only.Centralized management of VVRVVR can be centrally managed through the Storage Foundation ManagementServer. For more information, see the documentation for Storage FoundationManagement Server.Veritas Volume Replicator Advisor■Planning the SRL Size for Multiple RVG Configurations—VRAdvisorsupports SRL size planning for multiple RVGs that share the same networkbandwidth within the same configuration. It uses the bandwidth throttlingfeature to control the maximum network bandwidth to be used by VVR forreplication, thus enabling effective usage of the bandwidth by VVR andother applications. The results are displayed in a graphical and summaryview.
