Understanding resource usage
Unisphere supports a view of capacity utilization on a storage system throughout its life cycle.
The Unisphere capacity dashboard supports you to understand the storage system resources being used in the following scenarios:
Day 1: The storage system is installed and is ready for production:
- Can I see the physical disk capacity of the system?
- If I have purchased different disk technology tiers, can I see the capacity of each tier?
- Can I see how much effective capacity the system was sized for?
Day N: The storage system is in production, and storage is being provisioned:
- How much more can I write?
- How much more effective capacity is available?
- How much physical capacity is consumed?
- How much storage is allocated?
- How much of the system is over provisioned?
- What is the overall system Data Reduction Ratio (DRR)?
- How much capacity is not enabled for DRR?
- How much capacity is not reducible?
- How much capacity is being used by system resources that cannot be used for storage provisioning?
- How much system capacity is consumed by local replication?
- How much capacity is available for snapshots?
An overview of capacity terminology is displayed in the following figure.
A logical view in comparison with a disk consumption view is displayed in the following figure.
