Figure 10-12 Storage Insights versus Storage Insights Pro comparison  Storage Insights provides a very lightweight data collector that is deployed on a customer  supplied server. This can be either a Linux, Windows, or AIX server, or a guest in a virtual  machine (for example, a VMware guest). The data collector streams performance, capacity, asset, and configuration metadata to your  IBM Cloud instance. The metadata flows in one direction: from your data center to IBM Cloud over HTTPS. In the  IBM Cloud, your metadata is protected by physical, organizational, access, and security  controls. IBM Storage Insights is ISO/IEC 27001 Information Security Management certified. Metadata about the configuration and operations of storage resources is collected: Access to the metadata that is collected is restricted to the following users: Who can access the metadata What metadata is collected GLYPH<SM590000> The administrators who are authorized to access the dashboard, such as the customer’s  operations team GLYPH<SM590000> The customer who owns the dashboard GLYPH<SM590000> The actual application data that is stored on the storage systems can’t be accessed by the  data collector GLYPH<SM590000> Performance metrics, such as read and write data rates, I/O rates, and response times GLYPH<SM590000> Capacity values, such as capacity, unassigned space, used space and the compression  ratio GLYPH<SM590000> Inventory and configuration metadata for the storage system’s re sources, such as  volumes, pools, disks, and ports GLYPH<SM590000> Name, model, firmware, and type of storage system Chapter 10.
