    • A storage system includes a virtual volume, a plurality of RAID groups, a pool unit for managing a plurality of first real storage areas and a controller. If a write command related to the virtual volume is issued from a higher-level device, the controller selects a prescribed second real storage area from among respective second real storage areas included in a prescribed first real storage area, and associates this prescribed second real storage area with a prescribed area inside the virtual volume corresponding to the write command, and which associates one virtual volume with one first real storage area. A migration destination determination unit selects a migration-targeted second real storage area from among the respective second real storage areas associated with the virtual volume, and selects a migration-destination first real storage area, which is to become the migration destination of data stored in the migration-targeted second real storage area.
    • 存储系统包括虚拟卷,多个RAID组,用于管理多个第一实际存储区域的池单元和控制器。 如果从上级装置发出与虚拟卷有关的写入命令,则控制器从包括在规定的第一实际存储区域的各个第二实际存储区域中选择规定的第二实际存储区域,并将该规定的第二实际存储 具有与写入命令相对应的虚拟卷内的规定区域的区域,并且将一个虚拟卷与一个第一实际存储区域相关联。 移动目的地确定单元从与虚拟卷相关联的各个第二实际存储区域中选择迁移目标第二实际存储区域,并且选择迁移目的地第一实际存储区域,其将成为存储在其中的数据的迁移目的地 迁移目标第二实际存储区域。

    • The invention relates to exchanging micro programs in a storage device, automatically, without halting operation. In one embodiment, the path adapters of a host computer are connected to the input/output ports of respective clusters of a storage device, by respective connection paths. Path switching software is provided in the host computer, as well as database indicating connection destinations of the connection path. In the storage device, the input/output ports are connected to a group of a plurality of hard disk drive devices. An internal management device, and a database indicating the connection destination of each input/output port, are provided in the storage device. The management server device is connected to a host computer and a storage device, via a LAN, and a program exchanging program and micro programs to be used in exchange are provided in this management server device. Instructions for invoking the program are issued from the computer.

    • Memory resources are effectively utilized by visually setting an external memory resource as an internal memory resource. A first storage controller has a multilayer memory hierarchy constructed by LDEV (logical device) connected from LUN, and VDEV (virtual device) connected to the lower order of the LDEV. At least one of the VDEVs is constructed by mapping the memory resources arranged in external storage controllers. The functions of a stripe, RAID, etc. can be added in the mapping. Various kinds of functions (remote copy, variable volume function, etc.) applicable to the normal internal volume can be also used in a virtual internal volume by using the external memory resource as the virtual internal memory resource so that the degree of freedom of utilization is raised.
    • 通过将外部存储器资源可视地设置为内部存储器资源来有效地利用存储器资源。 第一存储控制器具有由从LUN连接的LDEV(逻辑设备)和连接到LDEV的较低阶的VDEV(虚拟设备)构成的多层存储器层级。 通过映射布置在外部存储控制器中的存储器资源来构造至少一个VDEV。 可以在映射中添加条带,RAID等的功能。 通过使用外部存储器资源作为虚拟内部存储器资源,也可以在虚拟内部卷中使用适用于正常内部卷的各种功能(远程复制,可变卷功能等),以便使用自由度 被提高
