Optimizing storage system behavior in virtualized cloud computing environments by tagging input/output operation data to indicate storage policy

摘要

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.

1. A method for optimizing storage system behavior in virtualized cloud computing environments, the method comprising:
reviewing data stored in a logical volume built on a logical storage container; building a map representing said logical volume indicating a range of block data in said logical volume that is to be excluded from being stored on a drive device and a range of block data in said logical volume that is to be considered for being stored on said drive device; transferring said map to a storage controller; and appending, by a processor, an input/output operation customer data with a tag, wherein said tag indicates a class of data which is associated with a storage policy in a cloud computing environment, wherein said storage controller applies said storage policy to said input/output operation customer data, wherein said storage controller applies said map to determine a storage location of said input/output operation customer data in said drive device.
