Entity Hierarchy

IO entities consist of two sets of objects: 1) those that are discovered and created automatically by the various Integrations and 2) those that are created by the user. Users may only create the seven entity types shown below: Tier, Application, Host, HBA Card, Storage Array, Storage Controller, Storage I/O Module. IO ships with four pre-defined Tier definitions, Tier 0, Tier 1, Tier 2, and Tier 3, but these can be replaced by the end user.

Important

Entity type names have both external (UI) and internal representations. Import files must use the internal entity type names. Please refer to the next section for information on finding the external to internal mapping of entity type names.

HBA Card, Storage I/O Module and Storage Controller entities are intermediary and, as such, could be considered optional entities. Meaning, Host entities can be created directly from HBA Port entities or Source IP Addresses and Storage Array entities can be created directly from Storage Port entities and Destination Ethernet Ports. However, as explained below, there are compelling reasons to employ them in customer environments.
