ABSTRACT:
In an embodiment of the invention, an apparatus uses a LUN (logical unit number) data type for storage allocation. The apparatus includes a storage appliance that specifies a LUN data type for a LUN. The storage appliance then allocates data blocks in the LUN based on the LUN data type. The storage appliance allocates data blocks in the LUN as contiguous data blocks or as non-contiguous data blocks, based on the LUN data type. The LUN data type may be, for example, database data type, user data type, or binary data type.
