HP XP P9000 Command View Advanced Edition Software - Manual (Page 46)

To externally connect an SMI-S Enabled storage system, execute it from CLI. For details about how to
use CLI to externally connect a storage system and disconnect an external connection, see the HP
P9000 Command View Advanced Edition Suite Software CLI Reference Guide.
Virtualizing volumes
Volume virtualization provides the capability to optimize storage services to applications by facilitating
movement of data between tiers and migration of data between different generations of technology.
Tasks to complete beforehand:
• The internal and external storage systems are registered in HP StorageWorks P9000 Command
View Advanced Edition Suite.
• The external storage system is connected to one or more external ports of the internal storage
system.
• External Storage Software is installed on the target storage system.
• Identify the number and capacity of volumes you are virtualizing.
• Identify the number of external paths between the external and internal storage systems.
1. From the Actions menu, select Virtualize Volumes.
2. Specify the appropriate information.
To change default values, click External Path Priority Settings, Host Group and LUN Settings, or
External Volume Configuration to specify new values.
3. Click Show Plan to review the plan and specify additional information, as appropriate:
• Verify the information that is displayed.
• Enter a name in Task Name.
• Specify when the task should run.
4. Click Submit.
The plan is registered as a task.
5. When the task completes, check the Storage Systems list to confirm that the external volumes are
mapped to the internal storage system.
Virtualizing storage capacity (THP/Smart)
This module describes how to virtualize storage capacity.
About virtualizing storage capacity
HP StorageWorks P9000 Thin Provisioning (THP) provides virtual volumes to a host and allocates the
actual capacity from a THP pool when a host makes a write request. By using THP pools, you can
allocate more capacity to a host than that allowed by the actual physical configuration of the storage
system.
THP pools provide the following advantages:
• You can reduce system setup and operational costs.
• You can use resources more efficiently.
• You can distribute workload equally among volumes.
Smart Tiers (Smart) improves THP pools storage performance further by taking advantage of
performance differences between hardware tiers.
