Abstract: A cluster includes a plurality of nodes including a storage unit that stores a program to be executed in response to a request from a client terminal connected to a network, and a processor that executes the program, in which, in a case where at least one substitute program stored in a substitute cluster is executed as a substitute for at least one target program stored in the cluster, when a request to the target program transmitted from the client terminal is acquired, a request transfer process of transferring the request to the target program to the substitute cluster is executed such that the substitute program is executed in response to the request to the target program.

Abstract: Performance deterioration of a storage system is prevented. A storage controller includes one or more processors, and one or more memories configured to store one or more programs to be executed by the one or more processors. The one or more processors are configured to execute conversion of converting metadata before conversion for controlling the storage system into metadata after conversion in a format corresponding to a new controller newly installed in the storage system, execute control of switching an access destination between the metadata before conversion and the metadata after conversion according to an access control code during the conversion, and access the metadata before conversion without using the access control code before start of the conversion.

Abstract: In each node constituting a storage system, there is at least one of a storage area (user area) in which a user data set is stored and a storage area (parity area). For the node having the user area, there is user part difference information including information indicating whether or not to be in presence of difference for each user area of the node. For the node having the parity area, there is parity part difference information including the information indicating whether or not to be in the presence of difference for each parity area of the node. Out of the parity part difference information, the information corresponding to the parity area is the information indicating the presence of difference when there is the information indicating the presence of difference in the storage area of any of the data sets used for generating the parity stored in the parity area.

Abstract: A method for application migrating from a first cluster to a second cluster. The method may include detecting application migration request from the first cluster to the second cluster for performing application migration; identifying first volumes associated with the first cluster that are used by the application; establishing data copying from the first volumes of a first storage device associated with the first cluster to second volumes of a second storage device associated with the second cluster; determining if a copy condition is met based on the data copying; for meeting the copy condition, stopping the application on the first cluster; flushing uncopied data from the first volumes to the second volumes; determining whether the flushing of the uncopied data is completed; and for the flushing of the uncopied data being completed, deploying the application on the second cluster.

Abstract: An object is to efficiently solve a quadratic programming problem having a k-hot constraint (k is a positive integer) for binary variables. A preferred aspect of the invention is an optimization method for, using an information processing apparatus, solving a quadratic programming problem in which one or more independent k-hot constraints are imposed on binary variables, the information processing apparatus including a processor, a storage device, an input device, and an output device. The information processing apparatus relaxes the binary variables into continuous values by adding correction values to a nonlinear coefficients of the binary variables on which the k-hot constraints are imposed, and the information processing apparatus executes a solution search while satisfying the k-hot constraints by executing a state transition such that a sum of a set of continuous variables on which the k-hot constraint is imposed is constant.

Abstract: A first node performs copy (virtual copy) of address mapping between a virtual volume and a pool to a first virtual volume to create a third virtual volume in the first node. A second node performs mapping from a first pool volume in the second node to the third virtual volume in the first node, links an address of the first pool volume, which is mapped to the third virtual volume, to an address of a second virtual volume in the second node on a one-to-one basis, and performs log-structured write of the data in the second virtual volume to a second pool volume in the second node.
