2.6.7 Storage provisioning
The RAID GUI provides three storage provision methods; simple,
symmetric, and selective. Whenever you change the method, the
following confirmation message is displayed. (iSCSI model support simple
method only)
• Simple method
Simple storage is used in direct attached storage (DAS) environments,
where there is no FC switch between the RAID and the hosts.
As the illustration shows, any
computer is allowed to access the
LUNs presented by the controller
after gaining access to the host
ports of the controller.
LUNs are assigned to each virtual
disk in RAID so the host can address
and access the data in those
devices.
Add LUNs in a storage port
In the simple storage main screen, click Add to add a LUN to the default
storage group of an FC port/SAS port/SCSI port/iSCSI port, fcpx/sasy/scpz/
isp, with a virtual disk.
