| The expansion of IT applications has resulted in more and more data being produced, making it necessary to manage high-capacity storage systems. One idea that has been put forward to solve these problems is the SAN(Storage Area Network).This paper studies the general function of storage management software based on SAN. Firstly, the wait control table function and timeout function is adpated to the system of backup and recovery so that they improve the performance and availablity. Secondly, there are so many same objects managed in the storage manage system and a greate deal of memory is occupied,and in order to access the resources between processes Entry management library is presented.Thirdly, this paper also researches the AG(Atomic Group) function , then implements an method to deal with the disater recovery in SAN and AG make users easier to operate than a volume. |
