Licensing examples
See how the capacity to be licensed and other values on the Managed Capacity page are calculated for different storage systems and configurations.
In these examples, SVC-1 is an IBM SAN Volume Controller and is monitored by IBM Storage Insights.
Example 1: Back-end capacity is not monitored
This example uses the following configuration:
- SVC-1 has no internal storage and does not receive capacity from storage systems other than the ones used in this example.
- Flash-1 is a Storwize V5000 with a 600 TiB RAID array.
Here's the situation:
- Flash-1 is not monitored by IBM Storage Insights.
- Flash-1 provides 300 TiB of capacity to SVC-1.
The following values are shown on the Managed Capacity page:
| Storage System | Capacity to be Licensed (TiB) | Monitored Back-end Capacity (TiB) | Unmonitored Back-end Capacity (TiB) | Total Capacity (TiB) |
|---|---|---|---|---|
| SVC-1 | 300 | 0 | 300 | 300 |
Explanation:
The 300 TiB Flash-1 capacity that is provided to SVC-1 is shown as unmonitored back-end capacity and is included in the capacity to be licensed for SVC-1.
The remaining 300 TiB capacity on Flash-1 is not provided to storage systems that are monitored by IBM Storage Insights and does not need to be licensed.
Example 2: Back-end capacity is monitored
Configuration:
- SVC-1 has no internal storage and does not receive capacity from storage systems other than the ones used in this example.
- Flash-1 is a Storwize V5000 with a 600 TiB RAID array.
Situation:
- Flash-1 is monitored by IBM Storage Insights.
- Flash-1 provides 300 TiB of capacity to SVC-1.
- SVC-1 receives an additional 800 TiB of capacity from other storage systems that are not monitored by IBM Storage Insights.
The following values are shown on the Managed Capacity page:
| Storage System | Capacity to be Licensed (TiB) | Monitored Back-end Capacity (TiB) | Unmonitored Back-end Capacity (TiB) | Total Capacity (TiB) |
|---|---|---|---|---|
| Flash-1 | 600 | 0 | 0 | 600 |
| SVC-1 | 800 | 300 | 800 | 1100 |
