    Abstract: A host I/F unit has a management table for managing an MPPK which is in-charge of the control of input/output processing for a storage area of an LDEV, and if a host computer transmits an input/output request for the LDEV, the host I/F unit transfers the input/output request to the MPPK which is in-charge of the input/output processing for the LDEV based on the management table, an MP of the MPPK performs the input/output processing based on the input/output request, and the MP of the MPPK also judges whether the MPPK that is in-charge of the input/output processing for the LDEV is to be changed, and sets the management table so that an MPPK which is different from the MPPK that is in-charge is to be in-charge of the input/output processing for the LDEV.

    Abstract translation: 主机I / F单元具有用于管理负责对LDEV的存储区域的输入/输出处理的控制的MPPK的管理表，并且如果主计算机发送对LDEV的输入/输出请求， 主机I / F单元基于管理表将输入/输出请求传送给负责LDEV的输入/输出处理的MPPK，MPPK的MP根据输入进行输入/输出处理 /输出请求，并且MPPK的MP还判断是否要改变负责LDEV的输入/输出处理的MPPK，并将管理表设置为与MPPK不同的MPPK， 负责为LDEV的输入/输出处理负责。

    Abstract: An intermediate device is disposed between a host and a search target. Search requests of m-multiplicity (requests involving a data transfer amount that is unknown to the host) for at least one among n-processes (n is an integer equal to or more than 1) to be executed by the host are issued as requests from the host to the intermediate device. A temporary area associated with the search requests is allocated in the host. For each of the search requests, the intermediate device recognizes a hit data volume in accordance with the search request within a search scope. For each of the search, the hit data is written in an area of the temporary area that corresponds to a write destination address. The write destination address is updated for each of the search requests on the basis of the recognized hit data volume.
