Abstract: An information processing apparatus includes a memory and a first processor and a second processor coupled to the memory. The first processor is configured to manage files in a storage apparatus and accesses to the files; and determine a migration target file from the files based on a history of the accesses to the files, the migration target file being to be migrated from a second storage medium to a first storage medium in the storage apparatus, the first and second storage mediums having different performances. The second processor is configured to control migrations of the files between the first storage medium and the second storage medium; and migrate the migration target file from the second storage medium to the first storage medium.

Abstract: A storage system includes a first control apparatus; at least one second control apparatus managed by the first control apparatus; and a storage unit accessed by the second control apparatus. The second control apparatus determines based on detection of an error of an input/output process for storage in the storage unit whether the storage is in a blocking state, executes a resumption process of the input/output process when the storage is in the blocking state, judges whether an error occurrence frequency of the input/output process is at least a predetermined value, when the storage is not in the blocking state, and transmits to the first control apparatus, a blocking process request for the storage, when the error occurrence frequency is at least the predetermined value. The first control apparatus executes a blocking process and an error process of the storage, based on reception of the blocking process request.

Abstract: A storage control device includes a processor. The processor is configured to receive a designation of a target volume among a plurality of volumes including a plurality of data pieces distributively arranged in a plurality of storage apparatuses. The target volume is to be migrated from a first storage apparatus among the plurality of storage apparatuses to a second storage apparatus different from the plurality of storage apparatuses. The processor is configured to determine a layout of first data pieces of the target volume on basis of a number of data pieces arrangeable in the first storage apparatus and a first number indicating a number of data pieces of the target volume. The processor is configured to perform a control operation, on basis of the determined layout, such that the first data pieces are arranged in the first storage apparatus and collectively migrated to the second storage apparatus.

Abstract: A virtual machine management device includes an acquiring unit, a specifying unit, and a move processing unit. The acquiring unit acquires an amount of communication data that is exchanged between multiple virtual machines running in multiple server devices and that is used for communication with each other. The specifying unit specifies, on the basis of the communication distance between each of the server devices, a server device that has a shorter communication distance from a server device, which executes one of a pair of the virtual machines whose amount of the communication data is equal to or greater than a predetermined amount, than a communication distance between the server devices in which the pair of the virtual machines are running. The move processing unit moves the other one of the pair of the virtual machines to the specified server device.

Abstract: A storage control device includes a processor that executes a process. The process includes conducting, on the basis of information related to distributed arrangement in a case when first divisional data obtained by dividing first data has been arranged distributedly in a first storage and in at least one different storage different from the first storage, control of relocating the first divisional data to the first storage from the different storage, and conducting control of moving the first data stored in the first storage from the first storage to a second storage after moving a control unit from the first storage to the second storage, the control unit being configured to conduct input or output control of the first data.
