# Storage systems registration

The Performance component of Unisphere collects performance data only after you register your storage systems. Only local storage systems can be registered for performance data collection.

## About this task

When you register a storage system for performance data collection, it takes at least two intervals (by default, 5 minutes each) before performance data begins to populate in the UI and charts. Before the data is populated, the UI and charts might display "NA" or remain blank. The collection of real-time data is performed at five-second intervals.

If a storage system is registered for real-time data collection, then by selecting a storage group, all devices in the storage group are also registered for the collection of real-time data. Only one storage system can be enabled for real-time storage group data collection at any given time, and a maximum of 100 storage groups in this array can be selected for collection.

Storage group real-time data collection is available only for storage systems running PowerMaxOS 5978. Real-Time performance data is also accessible through the REST API.
