About Shares
Each share has a configuration that is independent of other shares that reside on the same 
volume. A share configuration includes settings such as logbias, compression, deduplication 
(referred to as dedupe), protection, file-sharing protocols, and access rights.
The configuration settings of a share are stored in the volume (that is, in the pool) in which 
the share resides. This design allows a share to be portable when a disk is moved from one 
array to another array. You can specify whether a snapshot is created, and with what 
frequency it is created.
Note:
ReadyRECOVER creates and manages its own shares within the 
volume dedicated to ReadyRECOVER. Do not make changes to 
these shares. Do not create non-ReadyRECOVER shares within a 
ReadyRECOVER volume. For more information, see the 
ReadyRECOVER Software User Manual.
You can specify the size of a share in two ways:
Undefined. The entire nonreserved storage space on the volume is available to the 
share. Storage space is assigned on demand instead of up front. This method greatly 
improves the utilization rate of the share because storage space is assigned only as data 
is written to the share. The size of the share is reported as the entire nonreserved storage 
space on the volume. As data is written to the share, the used storage space is displayed 
on the volume icon in purple.
Quota. You set a quota for the share. All storage space that you specify when you create 
the share is also allocated up front. The share size cannot grow beyond the quota, but 
you can increase the quota. The size of the share is reported as the quota that you 
specify. As data is written to the share, the used storage space is displayed on the 
volume icon in purple.
Although the quota of an individual share cannot exceed the size of the volume, a volume 
allows oversubscription: The aggregate quota of the shares on a volume can exceed the 
size of the volume. Taking reserved storage space into account, storage space is 
assigned on demand.
In addition, whether you set a quota or not, you can reserve share storage space to 
guarantee that storage space is available on the volume. Snapshots, other shares, and LUNs 
on the volume cannot consume storage space that is reserved. The reserved storage space 
is displayed on the volume icon in orange.
