Storage management integrated system and storage control method for storage management integrated system
First Claim
1. An integrated storage management system in which access computers each having an auxiliary storage are coupled to each other via a network, said system comprising:
- a plurality of access computers; and
an integrated storage management server,wherein an access computer as the write source sends an inquiry about an access computer as a write destination to be written to the integrated server, said inquiry including file information of a file to be written by the access computer as a write source,wherein said integrated storage management server selects a candidate of said access computers as the write destination to be written and returns said candidate of said access computers to said access computer as the write source,wherein said access computer as the write source selects, when writing the file from the access computer as the write source, an access computer to be used as the write destination to be written which has been returned as the candidate, and writes a file to the access computer as the write destination thus selected as the write destination,wherein said integrated storage management server has policy information which defines a write policy that is used when said access computers are used as an access computer as a write destination,wherein said integrated storage management server uses said policy information and said file information in order to select said candidate of said access computers as the write destination to be written, andwherein said policy information is extracted from policy registration messages received from the access computers used as the write destination to be written.

Abstract
It is intended to achieve an arrangement wherein, when file information of shared disks which are distributed in a plurality of computers connected to a network are used, operating conditions at the time of accessing shared disks can be defined, thus enabling users to easily share files without being bothered by setting-up, or operations of computers located on the other side when they are to perform file sharing.
In order to achieve the above-stated arrangement, a storage management integrated server 100 is provided in a network, and respective computers register conditions, an accessibility states and use types pertaining to shared volume to be offered to the server. Thereafter, when a certain computer is to make a file accessing to a shared volume, the computer makes an inquiry to the storage management integrated server for an adequate access destination, determines, on the basis of a response from the server, computers which are suitable to the access source, and makes direct accesses to such computers.

10. An integrated storage management system, in which access computers each having an each auxiliary storage are coupled to each other via a network, said system comprising:
-
a plurality of access computers; and an integrated storage management server, wherein an said access computer as the write source sends an inquiry about an access computer as a write destination to be written to the integrated server, said the inquiry including file information of a file to be written by the access computer as a write source, wherein said integrated storage management server selects a candidate of said access computers as the write destination to be written and returns said candidate of said access computers to said access computer as the write source, wherein said access computer as the write source selects, when writing the file from the access computer as the write source, an access computer to be used as the write destination to be written which has been returned as the candidate, and writes a file to the access computer as the write destination thus selected as the write destination, wherein said integrated storage management server has policy information which defines a write policy that is used when said access computers computer are used as an access computer as a write destination, wherein said integrated storage management server uses said policy information and said file information in order to select said candidate of said access computers as the write destination to be written, and wherein said policy information managed by said integrated storage management server has definitions of a type of computer for indicating whether said access computer is always connected to said integrated management system or not, total available space of the auxiliary storage which is offered to other access computers, available time zone for indicating accessible time for other access computers, and priority of selection of an access computer as a write destination for indicating a degree when said access computer is selected by other access computers as a write source, for respective access computers.

11. A storage management control method of an integrated storage management system in which computers having each auxiliary storage are coupled to each other via a network, said integrated storage management system comprising:
-
a plurality of access computers; and an integrated storage management server; wherein said integrated storage management server has policy information which defines a write policy that is used when said access computers are used as an access computer as a write, said method comprising; a step in which said integrated storage management server receives a policy registration message from the access computer as a write destination and extracts said policy information from the policy registration message, a step in which said access computer as the write source sends an inquiry about an access computer as a write destination to be written to the integrated server, said inquiry including file information of a file to be written by the access computer as a write source, a step in which said integrated storage management server selects a candidate of said access computers as a write destination to be written to by said access computer as the write source by using said policy information and said file information, a step in which said integrated storage management server returns said candidate of said access computers as a write destination to be written to said access computer as the write source, and a step in which said access computer as the write source selects, when writing the file from the access computer as the write source, an access computer to be used as the write destination to be written which has been returned as the candidate, and writes a file to the access computer as the write destination thus selected as the write destination. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A storage management control method of an integrated storage management system in which computers having each auxiliary storage are coupled to each other via a network,
said integrated storage management system comprising: -
a plurality of access computers; and an integrated storage management server; wherein said integrated storage management server has policy information which defines a write policy that is used when said access computers are used as an access computer as a write; said method comprising; a step in which said access computer as the write source sends an inquiry about an access computer as a write destination to be written to the integrated server, said inquiry including file information of a file to be written by the access computer as a write source, a step in which said integrated storage management server selects a candidate of said access computers as a write destination to be written to by said access computer as the write source by using said policy information and said file information, a step in which said integrated storage management server returns said candidate of said access computers as a write destination to be written to said access computer as the write source, and a step in which said access computer as the write source selects, when writing the file from the access computer as the write source, an access computer to be used as the write destination to be written which has been returned as the candidate, and writes a file to the access computer as the write destination thus selected as the write destination, wherein said policy information managed by said integrated storage management server has definitions of a type of computer for indicating whether said access computer is always connected to said integrated management system or not, total available space of the auxiliary storage which is offered to other access computers, available time zone for indicating accessible time for other access computers, and priority of selection of an access computer as a write destination for indicating a degree when said access computer is selected by other access computers as a write source, for respective access computers.
