Monitoring the UR system

Parent Topic

• Universal Replicator

  Universal Replicator provides asynchronous, real-time replication of data from one storage system to another over any distance to satisfy the most demanding business continuity and disaster recovery requirements. While conventional replication solutions push updates from the primary storage system to a remote location, Universal Replicator at the remote site pulls changes from journal volumes maintained by the storage system at the primary site. This approach offloads replication overhead from the primary storage system and dramatically reduces the impact of replication on the business application. Transmitted record sets include a sequence number, enabling the replication engine to verify receipt of all records at the remote site and to sequence writes in the correct order for storage replication.

Child Topics

• Monitoring pair activity, status, license capacity

  Monitoring pairs, journals, data paths, I/O, licensed capacity, and hardware performance is essential for ensuring that Universal Replicator pairs continue to function correctly.

• Suspend conditions for Universal Replicator pairs
• Monitoring UR pair synchronization rate

  You can check the percentage of synchronized data between the P-VOL and S-VOL.

• Monitoring UR operations history

  In HDvM - SN you can review the history of operations for each pair, including a description of each operation, the date and time the operation took place, primary and secondary storage system information, and other details.

• Pair operations history
• Saving pair information to a text file

  In HDvM - SN you can save pair status and other information to a tab-delimited TSV file.

• Monitoring copy operations and I/O statistics

  You can monitor copy operations and I/O statistics to determine the replication performance.

• Monitoring I/O and hardware performance with Performance Monitor

  The Performance Monitor software provides detailed information on I/O activity and hardware performance.

• Monitoring journal (mirror) status

  The status of a mirror associated with a journal relates to the pair operations that have been performed on the journal. Monitoring these statuses can help to resolve problems and maintain the Universal Replicator system.

• Monitoring UR remote connections and path status

  You can navigate to remote connection and remote path status to determine any issues with the remote paths.
