Abstract
A storage system includes a storage device for storing data, a pair of adapters connected with the storage device, each of the adapters transmitting and receiving the data to and from the storage device respectively. The storage system includes a controller, connected with the adapters, for collecting performance information indicating performance of each of the adapters, comparing the collected performance information of the adapters with each other, and detecting a suspected adapter that is suspected of having a performance failure on the basis of a result of the comparison.
Claims10
A storage system comprising:
- a storage device that stores data;
- a pair of adapters connected with the storage device, each of the adapters transmitting and receiving the data to and from the storage device by using a same network path;
- and
- a controller, connected with the adapters, to collect operating ratios indicating performance of each of the adapters, to compare the collected operating ratios of the adapters with each other, and to detect a suspected adapter that is suspected of having a performance failure on the basis of a result of the comparison.
A control method for controlling a storage system includes a storage system includes a storage device for storing data, and a controller connected with the adapters, the storage method comprising:
- collecting performance information indicating performance of each of the adapters, each of the adapters being connected with the storage device and transmitting and receiving the data to and from the storage device by using a same network path,
- collecting operating ratios indicating performance of each of the adapters;
- comparing the collected operating ratios of the adapters with each other;
- and
- detecting, by using the controller, a suspected adapter that is suspected of having a performance failure on the basis of a result of the comparison.
A storage medium storing a control program for controlling a storage system includes a storage system includes a storage device for storing data, a pair of adapters connected with the storage device, each of the adapters transmitting and receiving the data to and from the storage device respectively, and a controller connected with the adapters, the control program causing a computer to execute an operation comprising:
- collecting performance information indicating performance of each of the adapters, each of the adapters being connected with the storage device and transmitting and receiving the data to and from the storage device by using a same network path,
- collecting operating ratios indicating performance of each of the adapters;
- comparing the collected operating ratios of the adapters with each other;
- and
- detecting, by using the controller, a suspected adapter that is suspected of having a performance failure on the basis of a result of the comparison.
