A monitoring unit acquires load information on a Tier pool that includes therein a plurality of volumes. A maximum performance calculating unit calculates an entire bandwidth of the Tier pool on the basis of the load information on the Tier pool acquired by the monitoring unit. A bandwidth management unit calculates each individual bandwidth such that the sum of the individual bandwidths allocated to each of the volumes corresponds to the entire bandwidth calculated by the maximum performance calculating unit and allocates each of the calculated individual bandwidths to each of the volumes.

Storage management device, storage management method, and computer-readable recording medium

An operation management server that manages a storage apparatus in which volumes are included and data is sent and received via transmission resources is provided. The operation management server includes a setting unit that sets a target value of the performance to some or all of the volumes; a monitoring unit that monitors the load factor of the transmission resources; and a bandwidth management unit that specifies a target transmission resource on the basis of the load factor of the transmission resources, that decides, on the basis of the target value, bandwidth allocation of some of the volumes that use the specified transmission resource, and that instructs a bandwidth control unit in the storage apparatus to adjust the bandwidth on the basis of the decided bandwidth allocation.

Storage management device and control method

A reception unit receives an input of designation of a performance level for a volume. A target value calculation unit obtains a target value of performance of data transmission and reception with respect to the volume according to the input performance level. A setting unit sets the target value obtained by the target value calculation unit for the volume. A monitoring unit monitors a load factor of a transmission resource. A bandwidth management unit identifies a target transmission resource based on the load factor of the transmission resource, decides a bandwidth allocation to a memory unit that uses the target transmission resource based on the target value, and instructs a bandwidth control unit of a storage device to tune the bandwidth using the decided bandwidth allocation.

Storage management device, and performance tuning method

A monitoring unit acquires load information on a Tier pool that includes therein a plurality of volumes. A maximum performance calculating unit calculates, on the basis of the load information on the volumes acquired by the monitoring unit, an entire bandwidth of the Tier pool. A bandwidth management unit calculates, on the basis of the minimum guarantee bandwidth for each of the predetermined volumes, each of individual bandwidths such that the sum total of the individual bandwidths allocated to the respective volumes corresponds to the entire bandwidth calculated by the maximum performance calculating unitand allocates the calculated individual bandwidths to the respective volumes.

A preliminary investigation execution unit sequentially sets a plurality of target values for each of predetermined times and then executes adjustment of a bandwidth of a storage apparatus on the basis of each of the set target values. A performance information acquisition unit obtains performance information for each of predetermined times regarding a business server in a case where adjustment of a bandwidth by the preliminary investigation execution unit is not performed, and obtains the performance information regarding the business server for the predetermined time for each of the target values in a case where adjustment of the bandwidth is performed by the preliminary investigation execution unit. A notification unit notifies the performance information obtained. A bandwidth management unit adjusts a bandwidth of the storage apparatus on the basis of a specific target value, on the basis of an input of the specific target value after notification.

Storage management apparatus, storage apparatus management method, and computer-readable recording medium

A guarantee value setting unit stores therein a guarantee value of data send/receive performance with respect to a predetermined volume in a plurality of volumes held by a storage device. A bandwidth management unit calculates an interim target value on the basis of a comparison result between the guarantee value and an actual measurement value of the data send/receive performance with respect to the predetermined volume, allocates, on the basis of the interim target value, a bandwidth that compensates a difference between the guarantee value and the actual measurement value with respect to the predetermined storage area, and determines band distribution with respect to each of the volumes, and instructs the storage device to adjust the bandwidth in accordance with the determined band distribution.

Storage management device, performance adjustment method, and computer-readable recording medium

An operational management server manages a storage device that includes a plurality of types of disks having different performances. A setting unit sets a target value of a performance to a volume produced by using the different types of the disks. An allocation rate management unit determines allocation rates of the respective types of the disks included in the volume on the basis of the target value set by the setting unit, and instructs the storage device to reproduce the volume in accordance with the determined allocation rates.

Storage management apparatus, and performance adjusting method

The present invention provides a data file system with the processing speed being improved, a data access node, a brain node, a data access program storage medium and a brain program storage medium. A brain node receives a data access request a from a NAS client computer, refers to an association table in a hard disk to identify a data access node among data access nodes, and transmits a data access request to the data access node. The data access node accesses data designated by the data access request stored in a hard disk which the node is responsible for accessing and transmits the access result to the requesting NAS client computer.
