  • Patent number: 9760294
    Abstract: A management computer stores, in a memory, virtual logical volume management information showing information on virtual logical volumes provided to a host computer by a storage device, and pool management information showing information related to a use status of pools. The management computer acquires performance information related to an access to the storage device from the host computer, determines whether the acquired performance related to the access satisfies a predetermined first required performance, or not, and specifies any virtual logical volume which is a cause of the state based on the virtual logical volume management information if the first required performance is not satisfied. The management computer calculates a capacity consumption trend of the real area included in each pool based on the pool management information, creates a countermeasure for satisfying the first required performance implementable after a given time, and outputs the countermeasure to an output device.

  • Patent number: 9723080
    Abstract: A storage apparatus includes a storage unit for storing data read/written by a host computer and provides the host computer with a storage area of the storage unit as one or more volumes. The storage management computer includes a first memory for storing task information including contents of an operation process performed on the storage apparatus, as well as a scheduled starting time and scheduled termination time of a process. In the case where first task information is stored in the first memory, when resources used in the process of second task information stored in the first memory are the same as resources used in the process of the first task information, the storage management computer computes times required for executing the first task information and the second task information, based on a time during which the processes of the first and second task information conflict with each other.

  • Patent number: 9639435
    Abstract: A management computer stores an operation requirement of a virtual machine and a scheme of a first configuration change executed by a host computer or a storage apparatus. The management computer determines whether a second configuration change configured so as to be executed automatically in the host computer or the storage apparatus is executed. If it is determined that the second configuration change is executed, the management computer predicts a performance index value concerning a prescribed performance index for the computer or the storage apparatus when executing the second configuration change. The management computer determines whether an anticipated effect value of the configuration change scheme is satisfied based on the predicted performance index value, and creates a substitution plan satisfying both an operation requirement and an anticipated effect value of the virtual machine where it is determined that the anticipated effect value is not satisfied.

  • Publication number: 20160097765
    Abstract: An electrochemiluminescence method of detecting an analyte in a liquid sample and a corresponding analysis system. An analyte in a liquid sample is detected by first providing a receptacle containing a fluid comprising protein coated magnetic microparticles to a stirring unit. Stirring of the fluid is necessary since the density of the microparticles is usually higher than the density of the buffer fluid. Thus the microparticles tend to deposit on the bottom of the receptacle leading to an aggregation of the microparticles because of weak interactions. To obtain representative measurements a homogeneous distribution of the microparticles in the buffer fluid is necessary to ensure a constant concentration of microparticles for each analysis cycle. It is further necessary to provide disaggregation of the microparticles, which is also realized by stirring the fluid. Stirring is conducted with a rotational frequency that is adapted to the amount of fluid to be stirred.

  • Publication number: 20160054946
    Abstract: A management system manages a plurality of logical volumes in a storage system coupled to a host system. The plurality of logical volumes includes a first logical volume provided to the host system and a second logical volume. The management system manages the second logical volume as a duplicate of the first logical volume and a first state volume which is provided to the host system. The management system changes the second logical volume to a second state volume associated with the first logical volume, which is not a logical volume provided to the host system and which is on standby for a future use by the host system. The management system manages a data difference between data stored in the second logical volume and data stored in the first logical volume associated with the second logical volume if data is newly stored in the first logical volume.
