Computer system, computer and method for performing thin provisioning capacity management in coordination with virtual machines
First Claim
1. A management system for managing a storage system configured to provide one or more storage level virtual volumes associated with a first storage level pool and a server computer configured to provide one or more server level virtual volumes associated with a server level pool to which the one or more storage level virtual volumes belong, comprising:
- an interface device to communicate with the storage system and the server computer;
a storage device; and
a processor coupled to the interface device and the storage device,wherein the processor is configured to;
receive storage level pool information that includes information of the capacity of the first storage level pool from the storage system,store the received storage level pool information in the storage device,receive a server level pool information that includes information of the capacity of the server level pool from the server computer,store the received server level pool information in the storage device,calculate a leverage ratio which is a ratio of total capacity of the one or more server level virtual volumes corresponding to the first storage level pool, to capacity of the first storage level pool, based on the storage level pool information and the server level pool information,compare the leverage ratio to a predetermined threshold value, andoutput information relating to a possibility of depletion of physical capacity has increased, when the leverage ratio is larger than the predetermined threshold value.

Abstract
In the computer system, a storage system provides a storage level virtual volume based on thin provisioning technology, to a physical server on which a virtual machine is defined. The storage system releases the area of the logical volume corresponding to the storage level virtual volume accessed by a virtual machine which is specified to be deleted, on the basis of storage level virtual volume conversion information which is managed by the storage system.

9. A computer system comprising:
-
a storage system configured to provide one or more storage level virtual volumes associated with a storage level pool; a server computer configured to provide one or more server level virtual volumes associated with a server level pool to which the one or more storage level virtual volumes belong; and a management system configured to manage the storage system and the server computer, wherein the management system is configured to; receive storage level pool information that includes information of the capacity of the first storage level pool from the storage system, receive a server level pool information that includes information of the capacity of the server level pool from the server computer, calculate a leverage ratio which is a ratio of total capacity of the one or more server level virtual volumes corresponding to the storage level pool, to capacity of the storage level pool, based on the storage level pool information and the server level pool information, compare the leverage ratio to a predetermined threshold value, and output information relating to a possibility of depletion of physical capacity has increased, when the leverage ratio is larger than the predetermined threshold value.

10. A management method for managing a storage system configured to provide one or more storage level virtual volumes associated with a first storage level pool and a server computer configured to provide one or more server level virtual volumes associated with a server level pool to which the one or more storage level virtual volumes belong, comprising a steps of:
-
receiving storage level pool information that includes information of the capacity of the storage level pool from the storage system; receiving server level pool information that includes information of the capacity of the server level pool from the server computer; calculating a leverage ratio which is a ratio of total capacity of the one or more server level virtual volumes corresponding to the storage level pool, to capacity of the storage level pool, based on the storage level pool information and the server level pool information, comparing the leverage ratio to a predetermined threshold value; and output information relating to a possibility of depletion of physical capacity has increased, when the leverage ratio is larger than the predetermined threshold value.
