Pure1 Metrics
The key Pure1 metrics used are the load metric, IOPS queue depth, file system space, data reduction and others.
- Load metric (%): Percentage value indicating the overall load of the array.
- IOPS queue depth: The queue depth of the array's I/O operations.
- File system space (GB): Physical space occupied by file system data on the array, excluding array metadata and snapshots
- Data reduction: Ratio of mapped sectors within a volume versus the amount of physical space the data occupies after data compression and deduplication. This does not include thin provisioning savings.
Performance Metrics
The key performance metrics used are Read, Write, and Total IOPs.
The metrics monitor:
- Total IOPs Read/Write Operations: Measures the total reads and writes per second to the storage location.
- Average Read/Write Operations per second: Measures the average reads and writes per second to the storage location.
- Average SAN Read/Write latency: Measures the average time required for an I/O to complete.
- Average Read/Write Throughput per second: Measures the average data transfer rate to and from the storage media.
- Queue depth: Measures the average number of outstanding I/O at the start of each incoming I/O operation.
The following table lists the performance metrics for the resource kinds.

Capacity Metrics
The capacity metrics detail how much storage is available to work with, the allocated storage, and the storage management.
The metrics are:
- Total physical space: Displays the total usable space on the array.
- Snapshot space: Displays the space utilization by the snapshots.
- Data reduction: Displays the data reduction in effect.
- Shared space: Displays the space shared between local and remote arrays.
The following table lists the resources and their associated metrics.
