One of the trickier problems facing storage administrators is managing asynchronous replication such as IBM Global Mirror. With asynchronous replication, the disaster recovery site is by nature somewhat behind the primary. This is acceptable but if things fall too far behind, the mirror could be suspended which may be considered an outage.
This video will show you how IntelliMagic Vision can be used to provide visibility to the status of Global Mirror replication in a Globally Disbursed Parallel Sysplex environment. Data about the Global Mirror sessions is recorded in SMF type 105 records which IntelliMagic Vision can analyze. By observing patterns and using drill downs, the root cause of the issue may be determined and potential outages avoided.
How Far Behind is My Asynchronous Replication?
Most peer-to-peer replication methodologies prioritize application performance over replication currency, but if replication falls too far behind you need to find out about it quickly and know what should be done to fix it.
