Abstract
A method and system for IO processing in a storage system is disclosed. In accordance with the present disclosure, a controller may take long term 'lease' of a portion (e.g., an LBA range) of a virtual disk of a RAID system and then utilize local locks for IOs directed to the leased portion. The method and system in accordance with the present disclosure eliminates inter-controller communication for the majority of IOs and improves the overall performance for a High Availability Active-Active DAS RAID system.
