Summary

This section is the table at the top of the Local Replication window that shows summary information about local replication.

The following image shows the summary section of the Local Replication window.

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

Item

Description

Number of Pairs

The number of pairs for each local replication software application type. The total number of pairs is shown on the Total line.

Number of Consistency Groups

The number of consistency groups that have a status other than "Free", and the consistency group limit in your storage system.

Number of Snapshot Groups

The number of snapshot groups that are in use and the snapshot group limit in your storage system.

Number of Pair Tables

The number of pair tables. This number varies depending on the combinations of software applications you are using.

Values:

  • SI/Volume Migration(VSP Gx00 models, VSP Fx00 models) The number of SI and Volume Migration pair tables in use, and the SI and Volume Migration pair table limit in your storage system.
  • SI/MF/Volume Migration The number of SI, SI-MF, and Volume Migration pair tables in use and the SI, SI-MF, and Volume Migration pair table limit in your storage system.
  • TI The number of HTI pair tables in use and the HTI pair table limit in your storage system.

Number of Differential Tables

The number of differential tables that are in use and the differential table limit in your storage system.

Because differential tables are not used for all operations, the number of differential tables does not change when you execute the following operations:

  • Thin Image pair operations.
  • SI-MF pair operations for a DP-VOL that exceeds 262,668 cylinders.
  • SI pair operations for a DP-VOL that exceeds 4 TB.

Snapshot Estimated Manageable Capacity

The HTI pair’s estimated manageable capacity, which is the estimated HTI pair capacity that you can create using the remaining shared memory capacity. This value varies depending on the amount of HTI P-VOLs you add or delete and the number or HTI pairs you create.

The icon is displayed if this item is less than the following value (depends on storage system model):

  • VSP G100, G200: 12 TB
  • VSP G400, G600, G800: 20 TB
  • VSP G1x00, VSP F1500: 128 TB

Note: This value does not guarantee that the HTI pairs of the indicated capacity have been successfully created.
