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. A volume can also have a volume belong
to multiple tiers.
In P9000 Command View AE Suite, 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 a license for an HP StorageWorks P9000 Tiered Storage
Manager software.
Also, HP P9500 (HP StorageWorks P9500 Disk Array), XP24000/XP20000,
XP12000/XP10000/SVS200 must be already registered.
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.
Prerequisites for allocating volumes from a tier
Before you allocate volumes from a tier, verify that:
• The hosts and storage systems are registered in P9000 Command View AE Suite.
Verify that P9000 Command View AE Suite detects the host and storage arrays by confirming
that the HP StorageWorks XP disk array is registered in P9000 Command View AE Suite.
