摘要： Provided is a management system for managing a relation between a database and a volume without installing an agent. A management system manages a relation between a data catalog and a volume of a storage system storing data to be used by the data catalog. A processor of the management system accesses data that is included in the data catalog and that includes authentication information of the volume; detects the number of accesses to the volume in a time range including a timing of the access to the data; and manages the relation between the data catalog and the volume on the basis of the number of accesses.

摘要： A resource allocation system calculates a performance ratio and a cost for each of a plurality of service tiers. For each of the service tiers, the performance ratio is a ratio of the intended performance to an agreement performance, the agreement performance is a performance that serves as a reference performance of the service tier, the intended performance is a performance calculated for the service tier, and the cost is based on a used capacity of an allocated storage resource among the storage resources belonging to the service tier. The system displays a service tier map that has an axis corresponding to the performance ratio and a second axis orthogonal to the axis and corresponding to the cost. A display object is placed, for each service tier, at a position according to the calculated performance ratio and the calculated cost of the service tier on the service tier map.

摘要： An object of the present invention is to provide a computer system and a scale-out method of the computer system that can reduce the possibility of occurrence of performance deterioration in the case where cloud bursting is executed.
In the case where scale-out is executed in a public cloud, a data processing system starts a data copy process of copying data stored in an on-premises first data storage area, to a second data storage area of a storage cluster in the public cloud via a first network. When starting the data copy process, the data processing system executes the scale-out by increasing the number of processing nodes while accessing the data stored in the first data storage area.

摘要： With respect to each of one or more entities, a computer sets a sum of an upper-limit NW send quantity and an upper-limit write quantity to a level equal to or lower than an allocation send quantity that is a send quantity allocated for the entity concerned. With respect to each of the one or more entities, the upper-limit NW send quantity is an upper-limit value of the NW send quantity that is the quantity of data to be sent per unit time via an NW I/F of the computer. With respect to each of the one or more entities, an upper-limit write quantity is an upper-limit value of a write quantity that is the quantity of data to be written per unit time to a logical volume recognized by the entity concerned.
