Thresholds for monitoring pools

Dynamic Provisioning monitors pool capacity using thresholds. A threshold is the proportion (%) of the used capacity of the pool to the total capacity of the pool, or the proportion (%) of the physical used capacity of the pool to the total capacity reserved for writing of the pool.

Parent Topic

• Configuring thin provisioning

  Thin provisioning technology allows you to allocate virtual storage capacity based on anticipated future capacity needs, using virtual volumes instead of physical disks. Thin provisioning is an optional provisioning strategy for your storage systems. Thin provisioning is implemented by creating one or more Dynamic Provisioning pools (DP pools) of physical storage space.

Child Topics

• Pool utilization thresholds

  When the used capacity of a pool reaches or exceeds the utilization thresholds set for the pool, you will be alerted so that you can take the appropriate action.

• Pool subscription limit
• Changing pool thresholds
• Changing the pool subscription limit

  Use this procedure to change the subscription limit of a pool.

• Controlling Thin Image pair behavior in a Dynamic Provisioning pool

  Use this procedure to control whether Thin Image pairs are suspended when the free capacity of a Dynamic Provisioning pool that contains Thin Image pairs and snapshot data is depleted.
