Abstract

A computer system comprises a storage system that is configured by at least one real storage apparatus that is provided with a plurality of real resources and a management system that is coupled to the storage system. The management system is configured to allocate a real resource or a virtual resource based on the real resource as a tenant resource from the at least one real storage apparatus to a tenant based on first information that includes an upper limit that is related to a real resource of each of at least one real storage apparatus that is provided with a plurality of real resources and second information that is an upper limit that is related to a real resource that is allocated as a tenant resource that is a resource that can be used by a tenant or as a resource that is a basis of the tenant resource.

Claims

1. A computer system comprising:

a storage system that is configured by at least one real storage apparatus that is provided with a plurality of real resources; and

a management system that is coupled to the storage system,

wherein the management system is configured to allocate a real resource or a virtual resource based on the real resource as a tenant resource from the at least one real storage apparatus to a tenant based on first information that includes an upper limit that is related to a real resource of each of at least one real storage apparatus that is provided with a plurality of real resources and second information that is an upper limit that is related to a real resource that is allocated as a tenant resource that is a resource that can be used by a tenant or as a resource that is a basis of the tenant resource.

2. The computer system according to claim 1,

wherein the at least one real storage apparatus is a plurality of real storage apparatuses;

and

wherein the management system is configured to allocate a real resource or a virtual resource based on the real resource as a tenant resource from the plurality of real storage apparatuses to the tenant.

3. The computer system according to claim 2,

wherein at least one tenant resource that has been allocated to the tenant or a plurality of real resources that are a basis of the tenant resource are distributed to the plurality of storage apparatuses.

4. The computer system according to claim 3,

wherein the tenant resource is a virtual resource;

and

wherein the second information is an upper limit that is related to the real resource that is a basis of the tenant resource.

5. The computer system according to claim 4,

wherein the upper limit that is related to the real resource is an upper limit for the number of the real resources.

6. The computer system according to claim 5, further comprising:

a virtual port that is allocated to a virtual storage apparatus based on a plurality of real storage apparatuses as a tenant resource,

wherein the plurality of real storage apparatuses is provided with a plurality of real ports based on a plurality of virtual ports; and

wherein the management system is configured to allocate a real port that is a basis of a virtual port that can be used by the tenant to the tenant based on the first information and the second information in the case in which a virtual port that can be used by the tenant is added.

7. The computer system according to claim 6,

wherein at least one real storage apparatus is configured to supply a real logical unit that is a logical storage device;

wherein the virtual storage apparatus is provided with a virtual logical unit to which a real logical unit that is included in at least one real storage apparatus that is a basis of the virtual storage apparatus has been allocated; and

wherein the management system is configured to allocate a virtual port to the tenant based on a rate of the number of real ports that is a basis of the virtual port and the number of real logical units that are handled by the real port and that have been allocated to a virtual storage apparatus.

8. The computer system according to claim 7, further comprising:

a virtual logical unit as a tenant resource,

wherein an upper limit that is related to a real resource is a capacity of a real logical unit that can be allocated based on at least one of the first information and the second information.

9. The computer system according to claim 8,

wherein the management system is configured to allocate a real logical unit that is a basis of a virtual logical unit that can be used by the tenant to the tenant based on the first information and the second information in the case in which a virtual logical unit that can be used by the tenant is added.

10. The computer system according to claim 2,

wherein at least one tenant resource that has been allocated to the tenant or a real resource or a plurality of real resources that are the basis of the tenant resource is aggregated to one storage apparatus.

11. The computer system according to claim 10,

wherein at least one real storage apparatus is configured to supply a real logical unit that is a logical storage device;

wherein the virtual storage apparatus based on a plurality of real storage apparatuses is provided with a virtual logical unit to which a real logical unit that is included in at least one real storage apparatus that is a basis of the virtual storage apparatus has been allocated;

wherein a virtual logical unit for a snapshot is provided as a tenant resource; and

wherein the management system is configured to allocate a real logical unit that is a basis of a virtual logical unit for a snapshot that can be used by the tenant to the tenant based on the first information and the second information in the case in which a virtual logical unit for a snapshot that can be used by the tenant is added.

12. The computer system according to claim 2,

wherein the management system is configured to allocate a real resource or a virtual resource based on the real resource as a tenant resource from the plurality of real storage apparatuses to the tenant based on the first information and the second information in the case in which a real storage apparatus is added to the computer system.

13. The computer system according to claim 3,

wherein the second information is an upper limit for a performance value of the tenant resource that is allocated to the tenant.

14. The computer system according to claim 1,

wherein the management system is configured to allocate a real resource or a virtual resource based on the real resource as a tenant resource from the at least one real storage apparatus to the tenant or a new tenant based on the first information and the second information in the case in which a real storage apparatus that can be used by the tenant is added or a tenant resource that can be used by the new tenant is added.

15. A resource management method comprising the steps of:

referring to first information that includes an upper limit that is related to a real resource of each of at least one real storage apparatus that is provided with a plurality of real resources and second information that is an upper limit that is related to a real resource that is allocated as a tenant resource that is a resource that can be used by a tenant or as a resource that is a basis of the tenant resource; and

allocating a real resource or a virtual resource based on the real resource as a tenant resource from the at least one real storage apparatus to a tenant based on the first information and the second information.
