Even without a first storage system does not have compatibility with a second storage system that is different from a default cloud storage service which can be accessed by a cloud computer service as a migration destination of a computer instance, a volume in the first storage system can be migrated to the second storage system. A system causes a migration tool of a cloud computer to migrate, from a first storage system to the cloud computer, a system volume storing an image of an OS for configuring a computer instance to be migrated, and a data volume storing data used by the OS, and creates a mapping volume, which has been mapped to the data volume migrated to the cloud computer with the migration tool, in a second storage system, and sets a path of data input/output from the computer instance to the mapping volume in the computer instance.

Information processing system and method

A speed reducing apparatus is provided which can prevent nonuniformity from occurring in output torque. A speed reducing apparatus that causes a first face gear to incline in such a manner as to mesh with a second face gear and causes the first face gear to oscillate in such a manner as to move a meshing portion in a circumferential direction includes a ball spline portion that supports the first face gear in an inclinable manner. The ball spline portion includes an outer ring, an inner ring, a ball capable of rolling along a ball groove of the outer ring and a ball groove of the inner ring, and a cage having a pocket in which the ball is incorporated, and allows axial displacement of the first face gear.

When having detected that key data set to an accelerator by command information is not key data permitted to use, a monitor unit issues, to a storage control unit, a suspension request for suspending processing related to writing of data, a compute unit having received an instruction from an application program reads data from the storage device, encrypts read data using the accelerator, and issues, to the storage control unit, an instruction to write encrypted data to the storage device, and when having received the suspension request, the storage control unit suspends processing related to writing of data to the storage device.

Information processing system

In a storage system that acquires data from a storage system via a network, in the storage system, a snapshot 108 with respect to a predetermined volume is managed, the storage system includes a CPU, and the CPU is configured to receive an acquisition instruction of data of a first snapshot of the predetermined volume and acquire at least a part of data of a difference between the first snapshot and a second snapshot from the storage system when data of the second snapshot of the predetermined volume is acquired.

Data acquisition of snapshots

Proposed are a storage system and a failure handling method capable of quickly recovering from a degeneration configuration when a failure occurs while reducing a cost required for system construction. A storage system is provided with one or a plurality of storage devices provided in a cloud system, one or a plurality of storage nodes provided in the cloud system, and a cloud control device configured to control the cloud system. The storage node is configured to request the cloud control device to prepare a new storage node when a failure of another storage node is detected, determine whether the storage device allocated to the storage node in which the failure occurs is failed, and request the cloud control device to allocate the storage device allocated to the storage node in which the failure occurs to the new storage node when the storage device is determined to be not failed.

Storage system and failure handling method

An object of the invention is to appropriately separate an available cluster for each user in a storage system configured by using a plurality of clusters each of which is an aggregate of nodes. A computer system includes a plurality of K8s clusters each configured by one or a plurality of K8s nodes, a storage that provides a volume, and a tenant management unit that manages the plurality of the K8s clusters and the storage. The tenant management unit creates, in the storage, a plurality of tenants respectively corresponding to the plurality of the K8s clusters. The storage, for each of the plurality of the K8s clusters, permits access from the K8s cluster to a tenant corresponding to the K8s cluster and prohibits access from the K8s cluster to a tenant not corresponding to the K8s cluster.

Information processing system for managing data storage and retrieval and method

One or more storage devices store resource migration schedule information including a plurality of records. Each of the plurality of records indicating a migration source node and a migration destination node of each of one or more resources. One or more processors are configured to determine a priority of each of the plurality of records such that a record having locality after migration has a higher priority than a priority of a record without locality after migration. The locality is determined based on whether a virtual machine and a volume associated with each other in advance exist in the same node. The one or more processors are configured to determine a migration schedule of each of the plurality of records based on the priority of each of the plurality of records.

Apparatus for determining resource migration schedule

Disclosed is a storage system that performs a drive data layout change while maintaining I/O functionality. The storage system creates a redundancy group for forming a redundant configuration of data to be stored in a storage drive, and stores data of the redundancy group in a plurality of the storage drives. A processor in a storage node discards data stored in a unit storage area, recovers the discarded data according to a changed data format, and re-stores the recovered data in the storage drive. The processor in the storage node performs an I/O process on the data to be discarded during a data format change, by achieving recovery based on the data of the redundancy group that is stored in an area other than the unit storage area where the data format is to be changed.

Storage system and data layout conversion method in storage system

A volume to be accessed by a host is provided. A reliability policy related to data reliability and a performance policy related to response performance to an access to the volume are set in the volume. A node that processes redundant data of data for a node that processes the data related to the volume is determined based on the reliability policy. The determined node returns a result of an access to the volume from the host according to the performance policy.

Storage system

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.

An access control system stores information defining conditions under which each user is allowed to perform resource access. The access control system acquires a first access request indicating an operation for a first resource in a target system by a first user, determines based on the information whether or not the first access request is permitted, acquires a result of an additional permission/disapproval determination of the first access request in response to the disapproval determination of the first access request, and grants execution authority of the first access request by the first user according to the result of the additional permission/disapproval determination indicating permission.
