Virtualizing storage tiers (Smart)
This module describes how to manage data relocation for Smart volumes.
About virtualizing storage tiers
Smart Tiers functionality monitors the frequency at which data is accessed and relocates that data
based on the results. The user creates a pool that combines volumes of different cost performances,
such as combining high-speed volumes (SSD or SAS) with inexpensive low-speed volumes (SATA).
The data in this pool is then automatically relocated among the volumes. This relocation is performed
depending on the I/O load:
• high-load pages are allocated to high-speed volumes
• low-load pages are allocated to low-speed volumes
By using HP StorageWorks P9000 Command View Advanced Edition Suite software, you can fine-tune
settings related to the monitoring of Smart pools and data relocation depending on operating
conditions. By specifying settings that correspond to business conditions or the characteristics of certain
applications, you can optimize data placement, improve volume performance, and reduce costs
through the effective use of resources.
Smart settings that can be specified by using Command View AE Suite include:
• Monitoring Smart pools and relocating data - Smart pool monitoring and data relocation can be
performed. Monitoring and data relocation can be set to execute automatically by specifying a
