  • Patent number: 8886906
    Abstract: In recent years, data life cycle management, in which data is relocated from, for example, a new storage sub-system to an older storage sub-system in accordance with how new the data is or the frequency of use of the data, has become important. One technology for achieving data life cycle management is technology for migrating the contents of a storage area (“volume”) of a storage sub-system to another volume without affecting the host computer that uses the volume. In the present invention, when an associated source volume (for example, the source volume in a copy pair association) of a pair of associated volumes is migrated, migration of an associated destination volume (for example, the target volume in the copy pair association) is also controlled. In this way, it is possible to control the migration of a pair (or a group) of associated volumes in accordance with the user's requirements.

  • Patent number: 8802032
    Abstract: This invention provides an analyzer that has a liquid dispense pipette dispensing liquids with higher accuracy and precision at higher speeds. The analyzer includes a drive mechanism having a stepping motor as a power source. The drive mechanism transmits power from a rotation output shaft of the stepping motor to a moving unit for executing a target motion via at least one power transmission unit. The amount of idling of the moving unit stemming from the stepping motor getting driven in reverse is calculated from the amount of movement of the moving unit, from the amount of pulses fed to the stepping motor, and from the amount of remaining pulses so as to perform motion control of the drive mechanism accordingly.

  • Publication number: 20140037503
    Abstract: The present invention performs cleaning on the inner and outer surfaces of a dispensing nozzle without reducing the processing speed of a device. To achieve the object, a feature of the invention is that a dispensing nozzle rinse tank includes a rinse liquid supply port. More specifically, by suctioning rinse liquid from the rinse liquid supply port provided on the dispensing nozzle rinse tank and discharging the rinse liquid into the rinse tank, the inner and outer surfaces of the dispensing nozzle can be rinsed in a short amount of time. According to the invention, it is only required that a rinse liquid supply port be provided on the dispensing nozzle rinse tank, the structure is simple. Moreover, because the inner and outer surfaces of the dispensing nozzle can be rinsed in a short amount of time by shortening the movement distance of the dispensing nozzle, analyses can be performed without reducing the processing speed of the device.

  • Patent number: 8645750
    Abstract: A computer system functions to dynamically assign the storage capacity to the host computer. If an event such as a failure occurs in the logical resources, the performance requirements of the virtual volumes must be guaranteed to the host computer. Accordingly, the computer system comprising a storage apparatus, wherein the storage apparatus detects the occurrence of an event in the logical resources, compares the performance of the logical resources where the event occurred with the performance of the virtual volumes and, in accordance with the result of the comparison, sets the correspondence relationship of the virtual volumes to the logical resources.

  • Publication number: 20130297903
    Abstract: A memory stores first configuration information indicating a plurality of logical storage areas and a first condition defining a state of a storage apparatus as a trigger for the storage apparatus to move data. A CPU acquires: a second condition defining a state of a computer as a trigger for the computer to move a first object, which is stored in a first logical storage area among the plurality of logical storage areas and performed by the computer, to another one of the plurality of logical storage areas; second configuration information associating the first object and the first logical storage area; first state information indicating a state of the plurality of logical storage areas; and second state information indicating a state of the first object. If a state of performing data movement is set, the CPU identifies a cause of the state of performing the data movement.

  • Publication number: 20130198476
    Abstract: Management method refers to position management information indicating an installation position of each of storage apparatuses. Positions of a first storage apparatus including a first volume and a second storage apparatus including a second volume composing a copy pair with the first volume are specified from the position management information. A positional relationship between the first and the second storage apparatuses before data migration is determined. If the second volume is not to be migrated, a condition of a positional relationship after the data migration to be satisfied between a migration destination storage apparatus of data of the first volume and the second storage apparatus is determined. Storage apparatus which satisfies at least the condition of the positional relationship after the data migration is selected from the storage apparatuses as the destination storage apparatus.

  • Patent number: 8447941
    Abstract: In recent years reducing the operating cost of storage devices (hereafter, also referred to as storage sub-systems) has been an important task for the management of storage systems. As one method for solving this task, data life cycle management, in which data is relocated from, for example, a new storage sub-system to an older storage sub-system in accordance with how new the data is or the frequency of use of the data, has become important. One technology for achieving data life cycle management is technology for migrating the contents of a storage area (hereafter referred to as “volume”) of a storage sub-system to another volume without affecting the host computer that uses the volume. In the present invention, when an associated source volume (for example, the source volume in a copy pair association) of a pair of associated volumes (or groups) is migrated, migration of an associated destination volume (for example, the target volume in the copy pair association) is also controlled.

  • Patent number: 8364925
    Abstract: This storage system modifies the migration plan in accordance with the state of the migration destination when a plurality of volumes are migrated all at once. Migration-source volumes are migrated collectively to volumes inside the migration-destination storage apparatus. The user can make settings related to migration-source volumes and migration-destination volumes in a migration plan, and can establish a mid-process control plan for modifying the migration plan in the middle of processing. If a failure occurs in the migration-destination storage apparatus subsequent to the commencement of data migration processing, a processing method controller either cancels or temporarily halts the data migration processing, or changes the migration destination, on the basis of the mid-process control plan. When changing the migration destination, a previously selected alternate storage apparatus is selected as the new migration-destination storage apparatus.

  • Patent number: 8285929
    Abstract: The management computer allocates a volume of an external storage device to a host so as to satisfy performance requirements specified from the host. The management computer selects a path that is formed including a first port of the storage device and a second port of the external storage device and that satisfies the performance requirements from the host, and then sets the priority. The management computer sets to the host the use authorization of a primary port and a secondary port that constitute a selected path and the use authorization of a second logical volume.

  • Patent number: 8281068
    Abstract: This invention provides, when optimizing a configuration of a storage system using a pool, an optimal configuration while ensuring a policy set by an administrator, the policy concerning a power saving performance, a response performance, or the like. The management computer sets, according to the set policy, priorities to volumes held by a storage subsystem, and reserves volumes satisfying the capacity of the pool, in descending order of the priority. Only some of the reserved volumes are registered for the pool in descending order of the priority. At this time, it can be guaranteed that a host computer makes no access to the volumes which have not been registered for the pool, and therefore the sleep state is set to physical drives forming the volumes or to a controller controlling the physical drives.
