    • Optimum load distribution processing is selected and executed based on settings made by a user in consideration of load changes caused by load distribution in a plurality of asymmetric cores, by using: a controller having a plurality of cores, and configured to extract, for each LU, a pattern showing the relationship between a core having an LU ownership and a candidate core as an LU ownership change destination based on LU ownership management information; to measure, for each LU, the usage of a plurality of resources; to predicate, for each LU based on the measurement results, a change in the usage of the plurality of resources and overhead to be generated by transfer processing itself; to select, based on the respective prediction results, a pattern that matches the user's setting information; and to transfer the LU ownership to the core belonging to the selected pattern.
    • 基于由多个不对称核心中的负载分布引起的负载变化,由用户进行的设定,选择并执行最佳负载分配处理,所述控制器具有多个核心,并且被配置为针对每个LU 基于LU所有权管理信息,示出具有LU所有权的核心和候选核心作为LU所有权更改目的地之间的关系的模式; 为每个LU测量多个资源的使用; 根据测量结果对每个LU进行谓词,改变多个资源的使用和由传输处理本身产生的开销; 基于相应的预测结果来选择与用户的设置信息匹配的模式; 并将LU所有权转移到属于所选模式的核心。

    • A first storage system that has a first storage device comprises a first interface device that is connected to a second interface device that a second storage system has. A first controller of the first storage system reads system information elements of first system information (information relating to the constitution and control of the first storage system) from a first system area (a storage area that is not provided for the host of the first storage device) and transfers the system information elements or modified system information elements to the second storage system via the first interface device. The system information elements are recorded in a second system area in a second storage device that the second storage system has.
    • 具有第一存储设备的第一存储系统包括连接到第二存储系统具有的第二接口设备的第一接口设备。 第一存储系统的第一控制器从第一系统区域(不为第一存储器的主机提供的存储区域)读取第一系统信息的系统信息(与第一存储系统的结构和控制有关的信息) 设备),并且经由第一接口设备将系统信息元素或修改的系统信息元素传送到第二存储系统。 系统信息元素被记录在第二存储系统所具有的第二存储装置中的第二系统区域中。

    • A hybrid-type storage system having both SAN and NAS interfaces can be implemented by simple hardware capable of carrying out a SAN function independently of a NAS function and a NAS load. To be more specific, a controller of the storage system comprises a NAS controller for accepting an I/O command issued for a file unit and a SAN controller for accepting an I/O command issued for a block unit. The NAS controller converts an I/O command issued for a file unit into an I/O command issued for a block unit, and transfers the I/O command issued for a block unit to the SAN controller. The SAN controller makes an access to data stored in a disk apparatus in accordance with an I/O command received from the SAN or from the NAS controller as a command issued for a block unit. The NAS and SAN controllers are capable of operating independently of each other.
    • 具有SAN和NAS接口的混合型存储系统可以通过独立于NAS功能和NAS负载进行SAN功能的简单硬件实现。 更具体地说,存储系统的控制器包括用于接受为文件单元发出的I / O命令的NAS控制器和用于接受为块单元发出的I / O命令的SAN控制器。 NAS控制器将为文件单元发出的I / O命令转换为为块单元发出的I / O命令,并将块单元发出的I / O命令传输到SAN控制器。 SAN控制器根据从SAN或从NAS控制器接收的I / O命令访问存储在磁盘设备中的数据,作为为块单元发出的命令。 NAS和SAN控制器能够独立运行。
