Computer system using a storage area network and method of handling data in the computer system
First Claim
1. A computer system which has plural client computers, plural various servers, plural various storages which keep data, a local area network (LAN) which connects said computers and said servers, and a storage area network (SAN) which lies between said servers and said storages, wherein said SAN forms a switched circuit network which is capable of connecting any said servers and any said storages through fiber channel switches (FC switches), said computer system comprising a terminal having operation and management software which performs storage management comprising management of logical volumes in said plural storages, data arrangement and error monitoring, management of setting up said FC switches, and a backup operation for data in said storages.

Abstract
In order to construct an integrated storage system by reinforcing collaboration of components or functions of a storage system in which a storage area network (SAN) is used, in a computer system comprising multiple client computers, multiple various servers, multiple various storages which keep data, a local area network (LAN) which connects the computers and the servers, a storage area networks (SAN) which lies between the servers and said storages, the SAN forms a switched circuit network which is capable of connecting any servers and any storages through fiber channel switches, and the computer system further comprises a terminal which is equipped with operation and management software which performs storage management including management of logical volumes in the various storages, data arrangement, and error monitoring, management of setting up said FC switches, and backup operation for data in said storages.

5. A method for managing a system having servers, a storage which keeps data of said servers, a network which connects said servers and said storage, and a backup device which is connected with said network and backs up said data, said method comprising:
-
a first step of obtaining information to identify data to be executed;
a second step of obtaining specification of processing a data denoted by said information;
a third step of instructing said storage which keeps the data denoted by said information to execute said specification of processing; and
a fourth step of receiving of processing the data denoted by said information from said storage result. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)
