Abstract:
A capacity control module which manages a physical storage area provided by each of storage devices in a cluster by dividing the physical storage area into a physical storage area having a predetermined size, in a plurality of storage nodes configuring a storage system, and, a storage control module which receives an I/O request from a higher-level device are provided, two storage control modules, which are arranged in different storage nodes and configure a redundancy configuration, are managed as a storage control module pair, the capacity control module preferentially allocates each of the physical storage areas in the vicinity of an arrangement destination of each of the storage control modules configuring the storage control module pair, to the storage control module pair, and storage data is read from or is written on the physical storage area, according to a command applied from the storage control module.

Claim (Index 9):
A control method of a storage system including a plurality of storage nodes,\n in which at least one of the storage nodes includes: a capacity control module which manages a physical storage area provided by each of storage devices configured of the plurality of storage nodes in a cluster; and a storage control module which receives an I/O request from a device at a higher level than a level of the plurality of storage nodes, generates a command according to the received I/O request, and transmits the command to the capacity control module to write or read data, wherein two or more storage control modules are configured by at least a first storage control module in a first storage node and a second storage control module in a second storage node, wherein the first storage control module is in a first state in which the I/O request can be processed, and the second storage control module is set to be in a second state in which the I/O request cannot be processed, and the storage system is configured to form a redundancy configuration of a data set including a plurality of data stored in different storage nodes, the method comprising: setting an exclusion storage node, which is a storage node that stores one data of the data set in the redundancy configuration and the data is stored in the physical storage area allocated to the two or more associated storage control modules; and allocating another physical storage area for storing other data of the data set in the redundancy configuration to the two or more associated storage control modules from a storage node other than the exclusion storage node.
