Possible tuning actions (without Smart Tiers)
. The following techniques using Business Copy
will move a THP V-VOL.
◦
The THP V-VOL is copied using Business Copy from a pool with an I/O bottleneck. For
more information, see the HP XP7 Business Copy User Guide.
◦
Business Copy copies a THP V-VOL with a high I/O load to a pool with a lower access
level to adjust the pool load.
Managing I/O usage rates example
The following figure illustrates an example of managing I/O usage rates.
Tuning with Smart Tiers
If Smart Tiers is active on your storage system, you can monitor access frequency and performance
use, and while Smart Tiers automatically relocates data to the most suitable data drive (tier). You
can configure monitoring to be automatic or manual. In both cases, relocation of the data is
automatically determined based on monitoring results.

Thresholds
Pool utilization thresholds
Thin Provisioning monitors pool capacity using thresholds. A threshold is the proportion (%) of used
capacity of the pool to the total pool capacity. Each pool has its own pool threshold values.
•
Warning Threshold: Set the value between 1% and 100%, in 1% increments. The default is
70%.
•
Depletion Threshold: Set the value between 1% and 100%, in 1% increments. The default is
80%.
