What Is a Storage Domain?
Storage domains are “containers” of physical and logical storage elements managed
by the system. When you create a storage domain, you create a functional virtual
network that is scalable and secure.
The user sees only the logical network that the storage domain creates. The storage
administrator sees all the storage elements available on the system, organizes them
according to need, assigns them different attributes, and creates data services that
will deliver data from one end of the network to the other (from storage device to
the host). Each storage domain is uniquely named and cannot be shared among
different clients.
For more information about the storage domains, go to the online help system by
clicking the Help button. Click the Search tab and type
storage domains.
Storage Domain Provisioning Considerations
To determine how to configure your system, you have to decide how you want to
use it, depending on your needs and the needs of your users. Do you want to use the
default configuration as is, with only one storage domain, or divide the system into
multiple smaller, but fully functioning, private, secure storage domains?
These storage domains create separate private, logical networks that can support
multiple clients within one Sun StorEdge 6920 system.
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.
Physical Components
Storage
arrays A storage array includes two controllers
(also referred to as a controller pair) to
provide redundancy and failover
capabilities.
Storage
trays Storage trays can contain from seven to
fourteen disk drives each.
Disks A disk is a non-volatile, randomly
addressable, rewriteable data storage
device. A tray can contain from seven to
fourteen disks.
