• FAST Cache knows what it was designed for and promotes data
according.
• It will not promote data that already resides on SSDs
• What is not considered for promotion (System Cache is used
instead)

Policy Ensures Storage Service Levels are Met
1. Start High, then Auto-Tier
Maximizes initial performance;
then optimizes for TCO
2. Auto-Tier
Optimize TCO and performance
e.g., databases with varied levels of
activity among tables, or file
systems with varied levels of
activity across files
3. Highest Available Tier
Maximize performance
e.g., high-performance OLTP
system
4. Lowest Available Tier
Reduce TCO
e.g., archived or infrequently
accessed data

– A LUN without a Host IO Limit is not impacted
– Does not limit internal IO (migration, replication, etc.)
– Host IO Limit settings can be changed at any time
