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 15):
A storage system, comprising:\n a plurality of storage nodes, wherein 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 a plurality of the 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 associated storage control modules are configured by at least a first storage control module arranged in a first node and a second storage control module arranged in a second 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 in a second state in which the I/O request cannot be processed, wherein the capacity control module is configured to allocate, to the two or more associated storage control modules, the physical storage area from the first storage node, the second storage node and from other storage nodes different from the first and second storage nodes, and wherein the storage system is configured to form a redundancy configuration of a data set including a master data stored in a master storage area and a slave data stored in a slave storage area, wherein the master data is stored in a first group of storage nodes including the first node in which the first storage control module is arranged and the slave data is stored in a second group of storage nodes including the second node in which the second storage control module is arranged, and wherein when allocating the physical storage area for storing the slave data of the data set in the redundancy configuration to the two or more associated storage control modules, the capacity control module sets the storage nodes of the first group which store the master data as exclusion storage nodes and selects a storage node, other than the exclusion storage nodes, from which the physical area is to be allocated to the two or more associated storage control modules so that the plurality of data of the data set in the redundancy configuration is stored in different storage nodes.
