摘要： The storage system provides a logical volume and includes a plurality of disk devices and a controller, coupled to the plurality of disk devices, which manages a plurality of storage areas provided by the plurality of disk devices. The host includes an application which sends data to a logical volume and an operating system which manages a block position of the logical volume. If the operating system receives a request from the application to expand a first capacity of the logical volume, the operating system sends a write request to the logical volume. In response to the write request, the controller allocates at least one of the plurality of storage areas to the logical volume. The controller monitors a second capacity of storage areas allocated to the logical volume relative to a third capacity of the plurality of storage areas.

摘要： During mirroring operations, de-duplication operations are applied to the mirror volumes. Data stored to a first volume is mirrored to a second volume. The second volume is a virtual volume having a plurality of logical addresses, such that segments of physical storage capacity are allocated for a specified logical address as needed when data is stored to the specified logical address. A de-duplication operation is carried out on the second volume following a split from the first volume. A particular segment of the second volume is identified as having data that is the same as another segment in the second volume or in the same consistency group. A link is created from the particular segment to the other segment and the particular segment is released from the second volume.

摘要： In some embodiments, an information system is divided into sections, with one or more first computers located in a first section and one or more second computers located in a second section, including a first temperature sensor sensing a temperature condition for the first section and a second temperature sensor sensing a temperature condition for the second section. In some embodiments, when heat distribution determined from the first and second temperature conditions is not in conformance with a predetermined rule for heat distribution, the information system is configured to relocate a portion of the processing load of the first computers to the second computers, or vice versa, for bringing the heat distribution into conformance with the rule. In some embodiments, the effect of other equipment, such as storage system or switches in the sections is also considered, and loads on this equipment may also be relocated between sections.

摘要： A storage system is configured to create and manage virtual ports on physical ports. The storage system can transfer associations between virtual ports and physical ports when a failure occurs in a physical port or a link connected to the physical port so that a host can access volumes under the virtual ports through another physical port. The storage system can also change associations between virtual ports and physical ports by taking into account the relative loads on the physical ports. When a virtual machine is migrated from one host computer to another, the loads on the physical ports in the storage system can be used to determine whether load balancing should take place. Additionally, the storage system can transfer virtual ports to a remote storage system that will take over the virtual ports, so that a virtual machine can be migrated to remote location.
摘要翻译：存储系统配置为在物理端口上创建和管理虚拟端口。当物理端口或连接到物理端口的链路发生故障时，存储系统可以传输虚拟端口和物理端口之间的关联，以便主机可以通过另一物理端口访问虚拟端口下的卷。存储系统还可以通过考虑物理端口上的相对负载来改变虚拟端口和物理端口之间的关联。当虚拟机从一台主机迁移到另一台主机时，可以使用存储系统物理端口上的负载来确定是否应进行负载平衡。此外，存储系统可以将虚拟端口传输到将接管虚拟端口的远程存储系统，从而将虚拟机迁移到远程位置。

摘要： The system includes a host, a backup server, a storage system having a journaling capability described above and a media library system. The storage system makes snapshots for restoring with journal at predetermined intervals in accordance with established process. Moreover, in correspondence to an instruction of the 1st type from the backup server, the storage system generates a marker of the 1st type to make snapshot to be provided to the backup. The storage system makes and provides a snapshot to the backup server according to the process of the 1st intended marker. Then the backup server takes a backup data from the snapshot. Furthermore, in correspondence to an instruction of the 2nd type from the backup server, the storage system generates a marker of the 2nd type to stop replication in the storage system. The storage system provides a quiescence image of a volume according to the process of the 2nd intended marker. Then the backup server takes a backup data from the quiescence image.

摘要： A system and method for managing disk space in a thin-provisioned storage subsystem. If a number of free segments in a free segment pool at a storage subsystem is detected as below a desired minimum, one or more of the following is performed: selecting and adding logical devices (LDEVs) from an internal storage as free segments to the free segment pool, transitioning LDEVs to a virtual device (VDEV), and/or selecting and adding LDEVs from an external storage as free segments to the free segment pool. The transitioning includes identifying partially used or completely used LDEVs and transitioning these to the VDEV. Data migration may also occur by: selecting a source segment at a VDEV for migration, reading data from the source segment, writing the data to a target segment, the target segment being a free segment from the free segment pool, and assigning the target segment to the VDEV.
