Abstract
A method, system and computer program product for optimizing storage system behavior in a cloud computing environment. An Input/Output (I/O) operation data is appended with a tag, where the tag indicates a class of data for the I/O operation data. Upon the storage controller reviewing the tag appended to the I/O operation data, the storage controller performs a table look-up for the storage policy associated with the determined class of data. The storage controller applies a map to determine a storage location for the I/O operation data in a drive device, where the map represents a logical volume which indicates a range of block data that is to be excluded for being stored on the drive device and a range of block data that is to be considered for being stored on the drive device. In this manner, granularity of storage policies is provided in a cloud computing environment.
