    摘要: The storage system is coupled to a computer and includes a plurality of physical storages being used to configure a first logical storage and a second logical storage, a control unit receiving a read request and a write request from the computer; and a cache memory storing data which is sent to the computer. The control unit determines whether a request from the computer is a write request or a read request. If it is a read request, the control unit reads data from the cache memory or at least one of the plurality of physical storages based on the read request. If it is a write request, the control unit determines whether destination of the write request is the first logical storage.

    摘要: A system and a method for causing migration of VNASs formed on NAS heads of one NAS system to other NAS heads on the same NAS system or on other NAS systems including independent storage systems. A VNAS management program on each NAS head includes a VNAS assign program, a failure detect program and a load balance program, that all include a capability for causing remote migration of VNASs on the NAS head in case a VNAS fails, the NAS head fails, or the entire NAS system fails. The VNAS management capability may cause VNAS migration if a NAS head is over loaded or if it is lightly loaded and may be powered down after its VNASs have been transferred.

    摘要: An integrated NAS/CAS system is disclosed. The system includes a view management program that is able to provide a NAS view and a CAS view of files to NAS and CAS clients. The system applied NAS or CAS features to stored files according to the view status of the file. Migration of files from NAS to CAS for archiving may be done without transmitting the file, thereby reducing bandwidth requirements and increasing security. CAS features, such as retention policy and metadata can be added to the file when its view is changed from NAS to CAS.

    摘要: A management device stores configuration history information indicating a history of system configuration changes, from this information, specifies a system configuration of a recovery time, which is a certain point in time in the past, specifies a system configuration of the current time, and compares the system configuration of the recovery time with the system configuration of the current time, and based on the results of this comparison, specifies whether or not there is a system configuration part in the system configuration of the current time for which, if data of the recovery time is recovered, a setting change is required in order to access this recovered data. When this system configuration part is specified, the management device constructs a system configuration for enabling a data utilization unit to access the recovered data by issuing an indication related to a required setting change to an element capable of carrying out the setting change for this system configuration part.

    摘要: In a cluster-structured disk subsystem, when creating a volume for an online backup separately from a volume for a normal I/O, it is desirable to be able to achieve such a creation for any volume under subsystem. Further, with an increase in the capacity of the subsystem, it becomes more difficult for a user to determine where to place a volume to which data is to be copied. Thus, a cluster-structured storage system is provided in which it is possible to reference/renew snapshot control information in shared memory of other clusters and achieve a snapshot between clusters via an inter-cluster connecting mechanism. In this system, control is performed inside/outside the cluster, and a control is performed inside/outside the cluster, and a volume to which data is to be copied is suggested to the user.

    摘要: A SAN manager acquires configuration information from devices constituting a SAN and produces a corresponding relationship between a host computer and a virtual volume (virtual volume mapping) and a corresponding relationship between the host computer and a real volume (real volume mapping). Based on those pieces of mapping information, the SAN manager outputs a corresponding relationship between virtual and real volumes. Meanwhile, the failure notification messages received from the in-SAN devices are construed to detect and output an influence of the failure upon the access to a real or virtual volume. Furthermore, when receiving a plurality of failure notifications from the devices connected to the SAN, the plurality of failure notifications are outputted with an association based on the corresponding relationship between real and virtual volumes.
