License use measuring and reporting

Information regarding the actual storage capacity usage (in Terabytes) on all your IBM Spectrum Accelerate deployments can be monitored from IBM® Hyper-Scale Manager.

Important: Always make sure that the total storage capacity of all Spectrum Accelerate deployments and newly added modules does not exceed the licensed storage capacity. If such exceeding is required, additional Spectrum Accelerate storage capacity must be licensed in advance.

The following figure illustrates the license use measuring and reporting concept:

License Metric Reporting

Spectrum Accelerate generates IBM® Software License Metric Tag (SLMT) files. Versions of IBM License Metric Tool that support IBM Software License Metric Tag can generate License Consumption Reports. Read this section to interpret these reports for Spectrum Accelerate.

If you have not installed a version of IBM License Metric Tool that supports IBM Software License Metric Tag, you can monitor the license usage from IBM Hyper-Scale Manager.

Each instance of a running Spectrum Accelerate runtime environment generates an IBM Software License Metric Tag file. The metric monitored is CAPACITY. It represents the system's hard capacity in Terabytes. The value is measured and refreshed every 7 days.

As long as the value of CAPACITY is smaller than the capacity allocated by your Spectrum Accelerate license, no action is required. If the value of CAPACITY exceeds the capacity allocated by your Spectrum Accelerate license, a new license must be obtained.

The system hard capacity (in Megabytes) can be also retrieved by issuing the command system_capacity_list.
