What is the recommended free space to maintain in ONTAP volumes and aggregates for optimal operation?
Applies to
ONTAP 9
Answer
- There isn't a comprehensive list detailing the requirements for all features.
- However, as a best practice, it's advisable to keep volumes and aggregates below 95% capacity (the default alert threshold).
- It's important to understand that continuous monitoring of storage usage is necessary, and assuming that monitoring is unnecessary after initial allocation is unrealistic.
Notes:
- In actual operations, the required free space may vary depending on system usage and snapshot management policies.
- If you actively use deduplication or compression, it is recommended to consider reserving more than 10% free space.
