SAN Storage Provisioning With "External" Load Balancing Mechanism

The Storage Load Balancing is just one part of the general load balancing problem in computer systems. The authors have storage controllers/processors, which act simultaneously and number of storage units which are known as volumes connected to those storage processors. The goal is to distribute those volumes, which also are called LUNs, among the storage processors in order to achieve better performance. LUNs actually are result of mapping previously created storage devices with the RAID Storage Systems to the computer SCSI devices in order to get these devices visible from host perspective. The focus in this paper would be only the FC-based (fibre channel based) SAN storage systems.
