Allocation
Description
Thick instant allocation
QTS allocates storage pool space when creating the
LUN. This space is guaranteed to be available later.
Thin provisioning
QTS allocates storage pool space only when needed,
such as when data is being written to the LUN.
This ensures efficient use of space but there is no
guarantee that space will be available.

Setting
Description
LUN name
• Length: 1 to 32 characters
