Summary section


Item	Description
Number of Pairs	The number of pairs for each local replication software type.
Snapshot Estimated Manageable Capacity*	The estimated HTI pair capacity. The icon appears when the estimated capacity is less than: VSP G1000 and G1500, and VSP F1500: 128 TB VSP G200: 12 TB VSP G400, G600, G800: 20 TB For more information about snapshot estimated manageable capacity, see the Thin Image User Guide.
Number of Consistency Groups	The number of consistency groups (CTGs) that have a status other than Free, and the maximum number of CTGs allowed.
Number of Snapshot Groups	The number of snapshot groups that are in use, and the maximum number of snapshot groups allowed.
Number of Pair Tables	The number of pair tables in use, and the maximum number of pair tables allowed. Values: (VSP G1000, G1500, and VSP F1500) SI/SIMF/Volume Migration: SI, SIz, Volume Migration (VSP Gx00 models and VSP Fx00 models) SI/Volume Migration: SI, Volume Migration TI: HTI
Number of Differential Tables	The number of differential tables in use, and the maximum number of differential tables allowed. 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 pair operations for a DP-VOL that exceeds 4 TB. (VSP G1000, G1500, and VSP F1500) SIz pair operations for a DP-VOL that exceeds 262,668 cylinders.
*Snapshot Estimated Manageable Capacity is an estimation of Thin Image pair capacity that is calculated by subtracting shared memory used by Thin Image pools and Thin Image pairs from the shared memory capacity. Snapshot Estimated Manageable Capacity is only a reference estimation and does not guarantee that the space is available. The Snapshot Estimated Manageable Capacity value changes when Thin Image pool volumes or Thin Image pairs are added or deleted.
