Managing storage tiers
This module describes how to manage tiers.
About tier-based storage management
In HP StorageWorks P9000 Command View Advanced Edition Suite, you must have a Tiered Storage
Manager license to perform tier-based storage management operations.
In a tier-based storage management system, storage system resources are grouped and managed in
tiers. Tiers can be created for volumes or for HP StorageWorks P9000 Thin Provisioning (THP/Smart)
pools to allow high-capacity resources to be centrally managed.
Tiers allow you to allocate data according to its purpose. This allocation can be done by grouping
drives in a storage system by type, or by creating groupings of particular tasks or functions. For
example, you can allocate frequently accessed data to a tier of high-reliability drives or storage
systems.
You can also use storage system resources more efficiently by storing data that is only for archive
purposes on a tier of SATA drives or older storage systems. A volume can also have a volume belong
to multiple tiers.
When you are managing a large variety of resources in tiers, you can check the performance status
of all the resources in the tiers at the same time, and you can select the migration-source and
migration-target volumes for data migrations from the tiers. By selecting tiers that match all the
requirements when volumes will be allocated to hosts, you can allocate all the necessary volumes
from the selected tiers at the same time.
Values to ensure acceptable tier performance
The values below ensure the operation of Tiered Storage Manager. Performance might slow down
or memory might become insufficient if a value exceeds these values.
