򐂰 Cold demote

Coldest extent moves to a lower tier.

򐂰 Expanded or cold demote

Demote appropriate sequential workload to the lowest tier to better use nearline

bandwidth.

򐂰 Swap

This operation exchanges a cold extent in a higher tier with a hot extent in a lower tier or

vice versa.

Figure 9-3 shows the Easy Tier extent migration.
