Storage system
First Claim
1. A storage system comprising:
- at least one first type disk devices each including an FC interface;
at least one second type disk devices each including an ATA interface; and
a controller coupled to said at least one first type disk devices and said at least one second type disk devices;
wherein said at least one second type disk devices configures a second type RAID group different from a first type RAID group configured with said at least one first type disk devices, andwherein a copy of data for a first type logical storage area, which is configured in said first type RAID group, is stored in a second type logical storage area configured in said second type RAID group.

Abstract
A disk array includes a drive management unit, which is a program for identifying kinds of disk devices and managing different disk devices separately, and a drive management table for storing information to be utilized by the drive management unit. The disk array further includes a program for managing accumulated time of disk devices. The program includes a drive lifetime setting portion for setting lifetimes of drives, a drive start/stop portion for intentionally starting/stopping ATA disk devices, and an operation time measurement portion for measuring accumulated operation time. Since it is necessary to be conscious of difference in reliability and performance among disk devices when forming a RAID, a drive kind notification unit, which is a program for notifying of the kind of a disk device when forming the RAID, is provided.

9. A data backup system comprising:
-
a source storage system including at least one first type disk devices each comprising an FC interface and a source controller coupled to said at least one first type disk devices; and a destination storage system including at least one second type disk devices each comprising an ATA interface and a destination controller coupled to said at least one second type disk devices, wherein said at least one first type disk devices configures a first type RAID group and said at least one second type disk devices configures a second type RAID group, wherein said source controller is configured to send replicated data for a first type logical storage area configured in said first type RAID group to said destination storage system to store said replicated data into a second type logical storage area configured in said second type RAID group, wherein the second type logical storage area is selected for storing said replicated data based on an interface type of said second type logical storage area. - View Dependent Claims (10, 11, 12, 13)

14. A data backup system comprising:
-
a source storage system including at least one first type disk devices each having a FC interface and a source controller coupled to said at least one first type disk devices; and a destination storage system including at least one first type disk devices each having FC interface, at least one second type disk devices each having an ATA interface, and a destination controller coupled to said at least one first type disk devices, said at least one second type disk devices, and said source controller, wherein said at least one first type disk devices in said source storage system configures a source first type RAID group, in which a source first type logical storage area is configured, said at least one first type disk devices in said destination storage system configures a destination first type RAID group, in which a destination first type logical storage area is configured, and said at least one second type disk devices in said destination storage system configures a second type RAID group, in which a second type logical storage area is configured, and wherein said source controller is configured to send replicated data for said source first type logical storage area to said destination storage system to store into said destination first type logical storage area, and said destination controller is configured to take a snapshot of data stored in said destination first type logical storage area by changing a pair state of a pair between said destination first type logical storage area and said second type logical storage area from a pair state to a split state. - View Dependent Claims (15, 16)

17. A storage system comprising:
-
first type disk devices each including a first type interface; second type disk devices each including a second type interface; and a controller coupled to the first type disk devices and the second type disk devices; wherein the controller configures a first type disk group with the first type disk devices and a second type disk group with the second type disk devices, based on interface types of the first type disk devices and the second type disk devices, and wherein a data copy operation from a first type logical storage area, which is configured in the first type disk group, to a second type logical storage area, which is configured in the second type disk group, is performed by the controller. - View Dependent Claims (18, 19)

20. A method for storing a copy of data for a logical storage area in a storage system, which comprises first type disk devices each including a first type interface, second type disk devices each including a second type interface, and a controller coupled to the first type disk devices and the second type disk devices, comprising:
-
configuring, by the controller, a first type disk group with the first type disk devices and a second type disk group with the second type disk devices based on interface types of the first type disk devices and the second type disk devices; configuring, by the controller, a first type logical storage area by using the first type disk group and a second type logical storage area by using the second type disk group; and executing, by the controller, a copy operation from the first type logical storage area to the second type logical storage area. - View Dependent Claims (21, 22, 23, 24, 25)
