Abstract
A storage control apparatus according to the present invention includes a plurality of connecting units connected to one or more host computers and one or more hard disk drives as storage media for storing data, one or more non-volatile storage media which are of a different type from the hard disk drives and which store data WRITE requested from the host computer, a plurality of processing units for processing WRITE and READ requests from the host computer by using the hard disk drives or the non-volatile storage media and, a plurality of memory units for storing control information to be by the processing units.
Claims5
A storage control apparatus comprising:
- a plurality of connecting units connected to one or more host computers and one or more disk drives as storage media for storing data;
- one or more non-volatile storage media which are a different type of storage media from that of the disk drives and which stores data WRITE requested from the host computer;
- a plurality of processing units for processing WRITE and READ requests from the host computer by using the disk drives or the non-volatile storage media and;
- a plurality of memory units that store;
- a user-specified requirement table for storing identification information on performance of storage media that a user specifies for data;
- a device determining requirement table for associating the storage media with performance thereof;
- and
- a usage status management table for associating an identifier for each storage medium with information on a usage status of each storage medium,
- wherein the processing units;
- inquire the user-specified requirement table and determine a user-specification for the data,
- inquire the device determining requirement table and the usage status management table and select storage media having performance that satisfies the user-specification for the data, and
- store the data on the selected storage media.
