Storage device and performance measurement method for the same
First Claim
1. A storage system including a storage device, a maintenance terminal for maintenance use of the storage device, and a plurality of host devices with respect to the storage device, whereinthe maintenance terminal includes a setting section that sets information for use to measure performance of the storage device, andthe storage device includes:
- at least one disk drive;
a plurality of volumes that are provided by the at least one disk drive, and each store therein data written by the plurality of host devices;
a detection section that detects any change made to information about a configuration of the storage system that includes at least one of an update of a program stored in the storage device or a paired combination among the plurality of volumes;
a measurement section that acquires, when the change of the configuration is detected by the detection section, the information set by the setting section, and based on the information, measures the performance of the storage device with respect to the data stored in the plurality of volumes; and
a transmission section that transmits, to the maintenance terminal, performance information about the performance being a measurement result by the measurement section.

Abstract
A storage system including a maintenance terminal, at least one disk drive, and a plurality of volumes that are provided by the at least one disk drive, and each store therein data written by the plurality of host devices. In this storage system, the maintenance terminal sets information for use to measure the performance of the storage device, and the storage device acquires the set information, measures the performance of the storage device with respect to the data stored in the plurality of volumes based on the information, and transmits, to the maintenance terminal, performance information about the performance being a measurement result. The storage system as such can collect information about the performance of a storage device that is not measurable from the side of the host devices, and a method for collecting such performance information can be provided.

7. A performance measurement method of a storage system including a storage device, a maintenance terminal for maintenance use of the storage device, and a plurality of host devices with respect to the storage device, wherein
the storage device includes: -
at least one disk drive; and a plurality of volumes that are provided by the at least one disk drive, and each store therein data written by the plurality of host devices, the method comprising; setting, by the maintenance terminal, information for use to measure performance of the storage device; detecting any change made to information about a configuration of the storage system that includes at least one of an update of aerogram stored in the storage device or a paired combination among the plurality of volumes; and upon a change of the configuration being detected, acquiring, by the storage device, the set information; measuring the performance of the storage device with respect to the data stored in the plurality of volumes based on the set information; and transmitting, to the maintenance terminal, performance information about the performance being a measurement result.
