• 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-TierMaximizes initial performance;then optimizes for TCO

2. Auto-TierOptimize 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 TierMaximize performance

e.g., high-performance OLTP system

4. Lowest Available TierReduce TCO

e.g., archived or infrequently accessed data

• System wide Pause/Resume control

– Paused by default

• Host IO Limits are based on a user created policy

– 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• Without Pausing/Resuming Host IO Limits on the system
