STORAGE SYSTEM AND METHOD FOR A STORAGE CONTROL APPARATUS USING INFORMATION ON MANAGEMENT OF STORAGE RESOURCES
First Claim
1. A storage control apparatus comprising:
- a plurality of communication ports each of which is connectable with any of a plurality of information processing apparatuses, are communicatively connected to a plurality of physical disk drives for storing data, receives a data I/O request for data stored in the physical disk drives from the information processing apparatuses, and performs data read/write from/to the physical disk drives in accordance with the received data I/O request;
a cache memory; and
storage resources which are partitioned into a plurality of storage resource groups each having one or more communication ports, storage capacity in said cache memory and one or more physical disk drives, wherein each storage resource group is assigned to an user, wherein said user is permitted to set a configuration of said one or more communication ports, said storage capacity in said cache memory and said one or more physical disk drives of said storage resource group assigned to said user; and
wherein in response to reception of a transmission request of information on management of a first storage resource group from a first user via a user interface, the storage control apparatus transmits an identifier of the one or more communication ports, an identifier of the one or more physical disk drives, and a storage capacity of the cache memory in the first storage resource group assigned to said first user.

Abstract
A storage control apparatus comprises a data I/O control unit which has communication ports adapted to connect with any of information processing apparatuses, is communicatively connected to physical disk drives for storing data, and performs data read/write from/to the drives according to a data I/O request received from the processing apparatus; a first memory storing a data read/written among the data stored in the disk drives; and a second memory storing information on management of storage resources including the communication ports, the physical disk drives, and a storage capacity of the first memory allocated for each user using the processing apparatuses. Upon reception of a request of the information on management from a user, an identifier of the communication port, an identifier of the disk drive, and a storage capacity of the first memory allocated for the user are transmitted to a user interface.

8. A method for controlling a storage control apparatus comprising a plurality of communication ports each of which is connectable with any of a plurality of information processing apparatuses, are communicatively connected to a plurality of physical disk drives for storing data, receives a data I/O request for data stored in the physical disk drives from the information processing apparatuses, and performs data read/write from/to the physical disk drives in accordance with the received data I/O request, a cache memory, and storage resources, said method comprising:
-
wherein said storage resources are partitioned into a plurality of storage resource groups each having one or more communication ports, storage capacity in said cache memory and one or more physical disk drives, wherein each storage resource group is assigned to an user, wherein said user is permitted to set a configuration of said one or more communication ports, said storage capacity in said cache memory and said one or more physical disk drives of said storage resource group assigned to said user;
receiving a transmission request of information on management of a first storage resource group of storage resources from a first user via a user interface; and
in response to reception of the transmission request of information on management of said first storage resource group from said first user via , said user interface, transmitting an identifier of the one or more communication ports, an identifier of the one or more physical disk drives, and a storage capacity of the cache memory in the first storage resource group assigned to said first user. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer program stored on a storage medium for controlling a storage control apparatus comprising a plurality of communication ports each of which is connectable with any of a plurality of information processing apparatuses, are communicatively connected to a plurality of physical disk drives for storing data, receives a data I/O request for data stored in the physical disk drives from the information processing apparatuses, and performs data read/write from/to the physical disk drives in accordance with the received data I/O request, a cache memory, and storage resources, said computer program when executed by said storage control apparatus comprising:
-
wherein said storage resources are partitioned into a plurality of storage resource groups each having one or more communication ports, storage capacity in said cache memory and one or more physical disk drives, wherein each storage resource group is assigned to an user, wherein said user is permitted to set a configuration of said one or more communication ports, said storage capacity in said cache memory and said one or more physical disk drives of said storage resource group assigned to said user;
code for receiving a transmission request of information on management of a first storage resource group of storage resources from a first user via a user interface; and
code for, in response to reception of the transmission request of information on management of said first storage resource group from said first user via said user interface, transmitting an identifier of the one or more communication ports, an identifier of the one or more physical disk drives, and a storage capacity of the cache memory in the first storage resource group assigned to said first user. - View Dependent Claims (16, 17, 18, 19, 20)
