Storage Management
208 Titan SiliconServer
The following will illustrate this scenario:
Rules
Pre-conditions
Rule 3 if free space is less than 15%.
Rule 2 if free space is less than 50%.
Rule 1 if no other condition applies.
When the Migration Policy is scheduled to run, different rules may be triggered based on the
available free space on Primary Storage. Remember, that when a Migration Policy has been
engaged, only a single rule will be triggered to run.
For example:
If free space is at 80%, then Rule 1 will be used.
If free space is at 40%, then Rule 2 will be used.
If free space is at 10%, then Rule 3 will be used.
When percentage thresholds are specified, they are evaluated based on whole number
percentages. This means that if two rules are specified, one that will take effect at 8% of free
space and one at 9% of free space, if the file system has 8.5% free space available, then the rule
with the 8% pre-condition will apply.
Note: If the Primary Storage defined in the Migration Path is a Virtual
Volume, free space will be based on the limit defined by the Virtual Volume
Quota . If a Virtual Volume quota has not been defined, then the free space
available will be based on the free space of the file system hosting the Virtual
Volume.
