摘要： The present invention provides improved techniques for managing storage resources, such as disk drives, I/O ports, and the like in a network based storage system according to a user position within the network. Embodiments according to the present invention can provide a relatively high performance storage access environment for the mobile users moving around a wide area. For example, in one applicable environment, there are several data centers in the wide area, and each data center has a local storage system that is connected to the other storage systems through a network. Copies of a user's volume can be made in some of the storage systems. A remote copy function is utilized for making real time copies of the user's volume.

摘要： In a system where a storage device is coupled to a computer, a storage area in the storage device is efficiently allocated to the computer. The system comprises a virtualization apparatus to be coupled to the virtualization apparatus. The virtualization apparatus, responding to a request from the computer, issues a notice to the effect that a predetermined size of virtual volume has been allocated to the computer. The virtualization apparatus, upon receiving an access request from the computer to the virtual volume, allocates storage areas existing in a plurality of storage devices to the virtual volume, converts the access request received from the computer to an access request addressed to a storage device having the storage devices allocated to the virtual volume, and transmits the converted access request to the storage device.

摘要： Conventionally, when a switch virtualizing a storage (storage virtualization switch) is installed in a computer system including an SAN, a host computer, and a storage device, since a port ID of a virtual storage and a port ID of a storage device assigned to the virtual storage are different, the computer system has to be suspended at the time of installation of the storage virtualization switch. According to one embodiment of the invention, the storage virtualization switch installed in the computer system assigns a port ID to a port of a virtual storage generated by the storage virtualization switch so as to be equivalent to a port ID of an existing storage device and, in the case in which the port ID is designated as an access destination by an access request from one computer to the storage device, sends the access request to the virtual storage.
摘要翻译：通常，当在包括SAN，主计算机和存储设备的计算机系统中安装虚拟化存储（存储虚拟化交换机）的交换机时，由于虚拟存储器的端口ID和分配给存储设备的存储设备的端口ID 虚拟存储不同，计算机系统必须在安装存储虚拟化交换机时暂停。根据本发明的一个实施例，安装在计算机系统中的存储虚拟化交换机将端口ID分配给由存储虚拟化交换机生成的虚拟存储器的端口，以等于现有存储设备的端口ID，在通过从一个计算机到存储设备的访问请求将端口ID指定为访问目的地的情况下，将访问请求发送到虚拟存储器。

摘要： A storage system is connected to a computer, and a name server exercising control over the interrelation between initiators and targets, and includes a first storage node and a second storage node. The first storage node has a first logical unit to which a first target is set, and the second storage node has a second logical unit. For data migration from the first logical unit to the second logical unit, the first storage node forwards data stored in the first logical unit to the second storage node, and the second storage node stores the data into the second logical unit. The first storage node also forwards information about the first target to the second storage node, and the second storage node sets a target to the second logical unit using the received information about the first target.

摘要： In order to avoid location of a buffer or a cache memory required for recovering a path trouble in the conventional storage unit, a new switch is provided between a computer and a storage unit. This switch manages a command to be relayed thereby, transmits to the computer an error response if the switch detects a trouble, and at a time changes a setting so that the subsequent commands may be transmitted through an alternate path.
