## About Storage Domains

Storage domains allow data to be isolated so that data from one host or set of hosts is protected from access by other hosts. In its default configuration, the system is provisioned with one storage domain called DEFAULT. This storage domain contains the Default storage pool with its associated disks and virtual disks.

To group servers together and provision storage for that group of servers only, you redefine the DEFAULT storage domain into two or more storage domains. A configuration with multiple storage domains provides an environment in which multiple servers share storage without compromising client security, as shown in the following figure:

You can create a maximum of 12 storage domains within one system. Within a storage domain, you can associate multiple storage pools. However, each storage pool can be associated with only one storage domain. For example, Storage Domain 1 can contain Storage Pools A, B, and C, and Storage Domain 2 can contain Pools D and E. However, Storage Pools A, B, and C cannot be associated with Storage Domain 2, and Storage Pools D and E cannot be associated with Storage Domain 1.

To see the current storage domains, go to the Storage Domain Summary page, as described in Displaying Domain Information.
