Abstract
The instant invention broadly contemplates balancing of asymmetric RAID arrays based on application usage patterns. The instantly claimed invention broadly contemplates balancing the type of workload and delivery of the work load in asymmetric RAID arrays by intelligently implementing different types of applications on disks strategically positioned to deliver workload to the RAID channel that is most capable of handling the work load. The invention makes use of the fact that some applications are more large block, sequential transfer dependant while other applications are more small block, high random, high IOP dependent, and places these applications accordingly within the asymmetric RAID array.
