Options
Set the level of physical capacity usage as a percentage (1-100 range) of
the physical THP/Smart pool capacity. When this threshold is exceeded,
it generates an alert, an email, or both. Alerts display on the Dashboard
and the Tasks & Alerts tab.
Used Threshold

Same description as above.
Used Threshold 1 and 2 display in the Pool Summary, in both graphic and
numeric values.

(Optional) Select Enabled to set subscription warning and limit thresholds.
Subscription
Thresholds
Exceeding the subscribed warning threshold (as a percentage of THP/Smart
pool capacity) generates an alert, an email, or both. Warnings are gener-
ated when volume allocation from a pool will exceed the warning level,
but volume allocation is still allowed (this is a soft limit). Alerts display on
the Dashboard and the Tasks & Alerts tab.
Warning
Exceeding the subscribed limit threshold (as a percentage of THP/Smart
pool capacity) generates an alert, an email, or both. However, if volume
allocation will exceed the subscribed limit threshold, volume allocation is
not allowed (this is a hard limit). You must either reduce the capacity of the
volume you want created, or increase the subscription limit.
Limit
(Smart options are only displayed when it is this pool type.)
By selecting this option, the storage system automatically starts and stops
performance monitoring and tier relocation based on the Cycle time and
Monitoring period settings.
Cycle time values range from 30 minutes to 24 hours. Monitoring period
are user-configurable time periods (for example, 13:00 to 19:00 hours).
Continuous and Periodic monitoring modes apply to both the Cycle time
and Monitoring period settings (for details, see Continuous Monitoring
mode).

Selecting this option lets you manually start and stop performance monitoring
and tier relocation.
Tier
management
Manual
Selecting this option lets you create performance monitoring and tier relo-
cation plans using templates with different types of performance monitoring
and tier relocation settings. You can create and delete templates by name,
set up monitoring periods (up to 7 days a week), set up relocation start
times (up to 7 days a week), and view these plans in the Schedule Summary
table. You can modify templates to meet specific needs. In addition, click
Pools using this template to assign a template to any pool that you select
from the Pools table.
Tier
management
Custom
Continuous monitoring mode uses weighted-average performance data
gathered over several monitoring cycles so that tier relocation does not re-
spond immediately to workload changes (see Cycle time). This mode prevents
overreaction to workload changes, that might otherwise result in unnecessary
tier relocation I/O.
