Storage system
First Claim
1. A program product, stored in a memory and executed by a controller of a storage system, wherein the storage system includes the controller, first interface type disk devices having first type interfaces, and second interface type disk devices having second type interfaces, the first type interfaces being different type interfaces from the second type interfaces, comprising:
- code for managing interface types of the first interface type disk devices and the second interface type disk devices;
code for configuring a first interface type RAID group by using the first interface type disk devices based on the interface types of the first interface type disk device; and
code for configuring a second interface type RAID group by using the second interface type disk devices based on the interface types of the second interface type disk devices.

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 ac-cumulated 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 program product, stored in a memory and executed by a controller of a storage system, wherein the storage system includes the controller, first type disk devices each having a first type interface, and second type disk devices each having a second type interface, the first type interface being different from the second type interface, the program product comprising:
-
code for configuring a first interface type disk group including the first type disk devices based on a type of interfaces of the first type disk devices, in the first interface type disk group a first interface type logical storage area being to be configured; and
code for configuring a second interface type disk group including the second type disk devices based on a type of interfaces of the second type disk devices, in the second interface type disk group a second interface type logical storage area being to be configured. - View Dependent Claims (10, 11, 12)

13. A storage system comprising:
-
first interface type disk devices each including a first type interface;
second interface type disk devices each including a second type interface; and
a controller coupled to the first interface type disk devices and the second interface type disk devices, wherein the first type interface is a different type interface from the second type interface, wherein the controller configures a first interface type RAID group by using the first interface type disk devices and a second interface type RAID group by using the second interface type disk devices based on interface types of the first interface type disk devices and the second interface type disk devices, and wherein a first interface type logical storage area is configured in the first interface type RAID group and a second interface type logical storage area is configured in the second interface type RAID group. - View Dependent Claims (14, 15, 16, 17, 18, 19)
