  • Patent number: 12045507
    Abstract: Each storage controller comprises a first storage unit, an interface unit, and a processing unit which sends, to the interface unit, a parameter which instructs n-fold write of writing data in each of n-number of (n is a natural number of 2 or more) other storage controllers. When the interface unit receives the parameter, the interface unit executes each processing of acquiring the data from the first storage unit and storing the data in the second storage unit, generating n-number of requests of writing the data in each of n-number of the other storage controllers, storing each of the generated requests in n-number of the queues corresponding to each of n-number of the other storage controllers, and processing each request stored in each queue and transferring the data stored in the second storage unit to each of n-number of the other storage controllers.
