Method and system for controlling information of logical division in a storage controller
A storage controller is realized in which validity/invalidity of functions is settable in a unit of logical division in conformity with logical division of logical groups control is performed such that operation has the influence upon only the inside of a range defined by resource groups of logical division and an Inband I/F for accessing functions is made to match with the logical division. Further, access control cooperative with information on the user side (information of server, user and application) is realized by causing a management server to manage information in the storage controller and user information.
1. A system comprising:
a host computer;
a plurality of storage systems each including a storage controller connected to the host computer; and
a management computer connected to the host computer and to said storage system,
wherein each said storage system comprises:
at least one interface unit to be coupled to the host computer;
a plurality of disk units configured to form a plurality of logical volumes;
at least one processor coupled to the interface unit and adapted to control access between the host computer and at least one of the disk units;
at least one memory unit adapted to hold write data and read data sent from the host computer and read from at least one of the disk units; and,
a plurality of logical groups each configured by at least one of the logical volumes and logically divided partitions of the processor, the interface unit and the memory unit,
wherein the memory unit is adapted to store structural information indicating the logical volume and the logically divided partitions of the processor, its throughput, the interface unit, its available function and an allotment rate of bandwidth of an internal network, belonging to each of the logical groups, and to store control information indicating whether a copy operation is allowed or not for each of the logical groups responsive to a copy request from the host computer, and
wherein the processors configured throughout the plurality of storage systems each include the storage controller and are adapted to limit access to one of the storage controllers of the plurality of storage systems,
wherein said one storage controller adds a user of the storage controller, selects suitable conditions required of the storage controller and adds new information to an information table, and
wherein the logically divided partitions of the processor of a logical storage controller set in compliance with user's conditions during setting are updated by adding a new unit of logical division.
2. The system according to claim 1 , wherein one of said plurality of logical groups comprises an Out of Band I/F for accepting therethrough an access to set in compliance with user's conditions.
3. The system according to claim 2 , wherein said interface unit is an Inband interface.
4. The system according to claim 1 , wherein correspondence relation information is stored in said memory unit by way of the management computer for management connected to said storage system.
5. The system according to claim 1 , wherein said predetermined information includes information of performance required of said one or plurality of logical groups.
6. The system according to claim 5 , wherein said processor sets said one or plurality of logical groups meeting said required performance in said storage system.
7. A system comprising:
at least one interface unit to be coupled to at least one computer;
a plurality of disk units configured to form a plurality of logical volumes;
at least one processor coupled to the interface unit and adapted to control access between the computer and at least one of the disk units;
at least one memory unit adapted to hold write data and read data sent from the computer and read from at least one of the disk units; and
a plurality of logical groups each configured by at least one of the logical volumes and logically divided partitions of the processor, the interface unit and the memory unit,
wherein the memory unit is adapted to store structural information indicating the logical volume, and the logically divided partitions of the processor, its throughput, the interface unit, its available function and an allotment rate of bandwidth of an internal network, belonging to each of the logical groups, and to store control information indicating whether a copy operation is allowed or not for each of the logical groups responsive to a copy request from the computer, and
wherein the processor is configured throughout the plurality of disk units and is adapted to limit access to one of storage controllers of the plurality of disk units,
wherein said one storage controller adds a user of the storage controller, selects suitable conditions required of the storage controller and adds new information to an information table, and
wherein the logically divided partitions of the processor of a logical storage controller set in compliance with user's conditions during setting can be updated by adding a new unit of logical division.
8. The system according to claim 7 , wherein one of said plurality of logical groups comprises an Out of Band I/F for accepting therethrough an access to set in compliance with user's conditions.
9. The system according to claim 7 , wherein said interface unit is an Inband interface.
10. The system according to claim 7 , wherein correspondence relation information is stored in said memory unit by way of a management computer for management connected to said system.
11. The system according to claim 7 , wherein said predetermined information includes information of performance required of said one or plurality of logical groups.
12. The system according to claim 11 , wherein said processor sets said one or plurality of logical groups meeting said required performance in said system.
