Manage FAST VP pool settings

Fully Automated Storage Tiering for Virtual Pools (FAST VP) is a storage efficiency technology that automatically moves data between storage tiers within a pool based on data access patterns.

The following table lists the attributes for FAST VP pool settings.

Table 1. FAST VP pool attributes
Attribute	Description
Pool	Identifies the pool.
Status	Identifies the status of data relocation on the pool. Value is one of the following: Not started - Data relocation has not started. Paused - Data relocation is paused. Completed - Data relocation is complete. Stopped by user - Data relocation was stopped by the user. Active - Data relocation is in progress. Failed - Data relocation failed.
Relocation type	Type of data relocation. Value is one of the following: Manual - Data relocation was initiated by the user. Scheduled or rebalancing - Data relocation was initiated by the system because it was scheduled, or because the system rebalanced the data.
Schedule enabled	Identifies whether the pool is rebalanced according to the system FAST VP schedule. Value is one of the following: yes no
Start time	Indicates the time the current data relocation started.
End time	Indicates the time the current data relocation is scheduled to end.
Data relocated	The amount of data relocated during an ongoing relocation, or the previous relocation if a data relocation is not occurring. The format is: <value> [suffix] where: value - Identifies the size of the data relocated. suffix - Identifies that the value relates to the previous relocation session.
Rate	Identifies the transfer rate for the data relocation. Value is one of the following: Low - Least impact on system performance. Medium - Moderate impact on system performance. High - Most impact on system performance. Default value is medium. NOTE:This field is blank if data relocation is not in progress.
Data to move up	The amount of data in the pool scheduled to be moved to a higher storage tier.
Data to move down	The amount of data in the pool scheduled to be moved to a lower storage tier.
Data to move within	The amount of data in the pool scheduled to be moved within the same storage tiers for rebalancing.
Data to move up per tier	The amount of data per tier that is scheduled to be moved to a higher tier. The format is: <tier_name>:[value] where: tier_name - Identifies the storage tier. value - Identifies the amount of data in that tier to be move up.
Data to move down per tier	The amount of data per tier that is scheduled to be moved to a lower tier. The format is: <tier_name>:[value] where: tier_name - Identifies the storage tier. value - Identifies the amount of data in that tier to be moved down.
Data to move within per tier	The amount of data per tier that is scheduled to be moved to within the same tier for rebalancing. The format is: <tier_name>:[value] where: tier_name - Identifies the storage tier. value - Identifies the amount of data in that tier to be rebalanced.
Estimated relocation time	Identifies the estimated time required to perform the next data relocation.
