For constructing high-performance database servers,it is essential to make the best use of parallel disks.It is important to execute load balancing among disks for parallel disks.Hence,proposed the net disk architecture for this purpose.This system can perform efficiently for dynamic load balancing even though the disk arrays are under heavy load conditions.The architecture also achieves high fault tolerance.In this paper,designed the Local Migration Manager(LMM) in the net disk architecture.At first defined message structure on the main bus to which the LMM is connected.Messages are splitted to transfer through the fixed size bus.Next defined LMM specification together with the internal data structure.Based on these,the algorithms of LMM are developed.
