摘要:
Provided is a computer system for identifying all physical resources which have been allocated to logical units before to be subject to shredding and for performing shredding on the identified physical resources. All the physical resources related to the physical resources specified by a user to be subject to data erasing are selected using usage history for the storage system. Moreover, a shredding task for the selected physical resources is generated according to configuration information of the storage system and shredding is performed based on the generated task. Consequently, the data is completely erased.

To provide a computer system, a management computer and a storage system, and a storage area allocation amount controlling method for improving I/O performance of the host computer. In a computer system comprising a storage system comprising one or more storage devices with storage areas, a host computer which uses a storage area of the storage device, and a management computer for dynamically allocating the storage area in response to an input/output request from the host computer; wherein the management computer monitors dynamic allocation of a real storage area to a storage area in the storage system, and calculates allocation increment amount to the allocated storage area based on the allocation frequency and the total amount of allocation.

Exercising integral management of storage apparatuses even when SANs are integrated or when the scale of a SAN expands. In response to an operation request from a management terminal, an integrated management computer collects the management information for storage apparatuses from management computers; selects, based on the collected management information, one or more management computers, to which the task of performing the requested operation is to be assigned, provides the selected management computer(s) with the ability to manage the storage apparatuses which are the management target for the management computer(s); collects pieces of process information from the management computer(s) with the management ability; and integrates and manages the collected pieces of process information.
摘要:
The management computer creates a connection between a virtual computer and a logical volume of a storage apparatus based on the application management information that stores a connection relationship between an application program and an I/O adapter, before a server computer provided with a hypervisor that logically divides the computer resources that include a CPU, a memory, and an I/O adapter and that operates them as an independent virtual computer starts an application program that has been stored into the storage apparatus on the virtual computer.
摘要:
The computer system includes: a first storage system having devices that are various components for storing data transmitted from a host computer; a second storage system having devices that are various components for storing data transmitted from the first storage system; and a management apparatus that manages the first and second storage systems. The management apparatus includes a storage unit that stores configuration information, performance information and threshold values used for performance management regarding the devices in the first and second storage systems connected to the management apparatus; and a setting section that adopts and sets, when internal management information and data are copied from the first storage system to the second storage system, threshold values assigned to the devices in the first storage system to the devices in the second storage systems.
