Abstract
In a storage system including a plurality of data controllers that receive a data input/output request that is input via an external communication path and perform data input/output processing with respect to a storage resource in response to this request, the plurality of data controllers being connected by a data communication path and being able to communicate with one another, if a data input/output request has been input into one of the controllers, the plurality of data controllers and shares execution of the data input/output processing by communication through the data communication path.

2. A method for load distribution among a plurality of data controllers that receive a data input/output request from an external communication path and perform data input/output processing with respect to a storage resource in response to the data input/output request, the plurality of data controllers being connected by a data communication path and being able to communicate with each another, the method comprising:
-
a first data controller from among the plurality of data controllers receiving the data input/output request;
the first data controller performing input/output operations with the storage resource on data associated with the data input/output request; and
a second data controller from among the plurality of data controllers performing parity calculations for the data associated with the data input/output request. - View Dependent Claims (3, 4, 5, 6, 7, 8)
