Section 3 - Configuration
Introduction:
In an iSCSI environment, LUNs are essentially numbered disk drives. An initiator negotiates with a target to establish connectivity
to a LUN; the result is an iSCSI connection that emulates a connection to a SCSI hard disk. The LUN can be created using the
following two methods.
Thin provisioning:
The space is allocated only when needed. Advantages of Thin Provisioning on the ShareCenter Pro. With thin provisioning, you
can flexibly allocate the disk space (on iSCSI LUN) to the server applications to expand the storage capacity anytime regardless
of their current storage size. The adding of the storage space on the servers can be easily done on different operation systems
by the iSCSI initiator. Thin provisioning allows efficient storage management since the system administrator has to monitor
only the storage capacity of one single server (ShareCenter Pro) rather than extra hard drives or tapes on other sub-storage
systems. Over-allocation is allowed since the storage capacity of the NAS can be expanded.
Pre-Allocate:
The space will be allocated now. If you create a 50 GB LUN, then 50 GB will be immediately reserved for that LUN. (Note that
the creation will also take more time because of that process).
