Reserving tier capacity when setting a tiering policy
If you set the tiering policy of a THP V-VOL, the THP V-VOL used capacity and the I/O performance
limitation are reserved from the tier. The reserved limit performance per page is calculated as
follows:
The reserved limit performance per page = (The performance limit of the tier) ÷
(The number of pages in the tier).
A THP V-VOL without a tiering policy setting uses the unreserved area in the pool.
