6.9 Viewing Remote Replication Performance Indicators
After an asynchronous remote replication pair is created and the pair status is normal, you can
view real-time performance indicators such as bandwidth, time past since last
synchronization, synchronization duration, and time difference (RPO).
Context
l Real-time performance data can be viewed only when performance monitoring is
enabled. If performance monitoring is not enabled, click Set Parameters to enable it.
l Only performance indicators of asynchronous remote replication are collected, and they
can be queried in the primary storage system only.
l The performance indicators include Block Bandwidth (MB/s), Logical Bandwidth
(MB/s), Interval since last synchronization (s), Time Difference(s), and
Synchronization Duration (s). Table 6-8 explains the indicators.
