Summary section

The following table shows the items in this section of the Local Replication window.


Item	Description
Number of Pairs	The number of pairs for each local replication software type.
Number of Consistency Groups	The number of CTGs that have a status other than "Free".
Number of Snapshot Groups	The number of snapshot groups in use and the maximum number.
Number of Pair Tables	The number of pair tables in use. Values: SI/Volume Migration: SI, Volume Migration TI: HTI
Number of Differential Tables	Number of differential tables in use. This is not used by HTI.
Snapshot Estimated Manageable Capacity^*	The estimated HTI pair capacity. The icon is shown if the value is less than 128 TB. For more information about snapshot estimated manageable capacity, see the Hitachi Thin Image User Guide.
* Snapshot Estimated Manageable Capacity is a estimation of a Thin Image pair capacity which can be created from remaining shared memory capacity after subtracting shared memory used by Thin Image pool and Thin Image pair. Snapshot Estimated Manageable Capacity is just a reference and it doesn't guarantee that Snapshot Estimated Manageable Capacity worth of Thin Image pair will be created.
