3–Data Migration ObjectsData Migration Job Groups3-2 ISR654608-00 BConfigure the array entity created by the DMS for the following attributes: Symbolic name: Upon forming an array, the iSR6200 Intelligent StorageRouter automatically assigns a symbolic name to an array. It is highlyrecommended that you assign a more meaningful name to an array becausethe migration logs identify the source and destination LUNs with thesymbolic names of the source and destination arrays. Array type: DMS requires the classification of each array as either Source,Destination, Source+Destination, or None. During the creation of migrationjobs, the Data Migration wizard restricts the assignment of a source LUNonly from arrays that have an attribute Source and assignment of adestination LUN only from the arrays with attribute Destination. Use thearray attribute Source+Destination only when you need to create copies of aLUN on the same array.Select the array type attribute None to exclude the storage array fromparticipating in data migration. The iSR6200 simultaneously supports bothiSCSI connectivity and data migration service. Typically, you would use the“None” attribute when the iSR6200 is used to provide only iSCSIconnectivity for that storage array. Array bandwidth: This feature is applied only to a source array. This valueindicates the maximum bandwidth the iSR6200 uses from the source arrayfor a data migration task. The bandwidth is computed over all paths. TheiSR6200 uses only the user-assigned array bandwidth to migrate the data.This allows other applications and servers using the same source array tocontinue to perform at an acceptable performance level. The minimumbandwidth required for data migration is 50MBps. Load Balancing: The iSR6200 detects all available active and passivepaths to the LUN. Load balancing balances the load for migration jobs overmultiple active paths, thus improving the migration rate. Disable loadbalancing only if there is a problem performing data migration.Data Migration Job GroupsThe iSR6200 uses the concept of job groups to associate data migration jobs withuser-defined groups. A job group allows better management of data migrationjobs. You can create a maximum of eight job groups. The SANsurfer RouterManager also has commands to remove and edit job groups.
