Managing storage tiers
This module describes how to manage tiers.
About tier-based storage management
In a tier-based storage management system, storage system resources are grouped and managed in
tiers. Tiers can be created for volumes or for Thin Provisioning (THP) 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.
In P9000 Command View AE Software, you must have an HP StorageWorks P9000 Tiered Storage
Manager software license to perform tier-based storage management operations.
Creating tiers
Before you can create a tier, you must enable an HP StorageWorks P9000 Tiered Storage Manager
software license.
To create a tier:
1. On the Resources tab, click Tiers.
2. Select the storage system in which to create a tier.
3. Click Create Tier.
4. Specify the appropriate information.
5. Click OK.
6. Confirm that the tier is included in the storage system selected in the Tiers tree.
