Method and system for placement of data on a storage device

摘要

Embodiments of systems and methods for a storage system are disclosed. More particularly, in certain embodiments locations of storage devices may be allocated to store data when commands pertaining to that data are received. Specifically, in one embodiment a distributed RAID system comprising a set of data banks may be provided where the different performance characteristics associated with different areas of disks in the data bank may be taken into account when allocating physical segments to corresponding logical segments of a volume by allocating certain physical segments to a particular logical segment based upon a location of the physical segment or criteria associated with the logical segment.
