About Provisioning Storage

In the default storage configuration, all data hosts are in one domain and all available storage is in one storage pool. Any host (initiator) in the domain can get access to any storage in the pool. However, your organization's needs determine how you adjust the storage configuration. Instead of assigning hosts to specific physical storage, you provision the storage for your organization by creating domains of initiators and pools of virtual storage.

In addition to domains and pools, the system has physical and logical storage elements that you use to provision your storage:

The relationships among the physical and logical storage elements is shown in the following diagram:

Before you can allocate storage appropriately, consider the following requirements for your site:
