    • A system and method for performing a search operation within a sequential access data storage subsystem are disclosed. According to one embodiment, a data storage subsystem is provided which comprises a search module and a communication channel interface to communicatively couple the data storage subsystem to a host data processing system via a communication channel. In the described embodiment, the search module is configured to receive search attribute data from the host data processing system via the communication channel interface, where the search attribute data specifies a search attribute. The search module is further configured to perform a search operation on data of a sequential access storage element utilizing the search attribute and to provide search result data to the host data processing system via the communication channel interface in response to a performance of the search operation.
    • 公开了一种用于在顺序访问数据存储子系统内执行搜索操作的系统和方法。 根据一个实施例,提供了一种数据存储子系统,其包括搜索模块和通信信道接口,用于经由通信信道将数据存储子系统通信地耦合到主机数据处理系统。 在所描述的实施例中,搜索模块被配置为经由通信信道接口从主机数据处理系统接收搜索属性数据,其中搜索属性数据指定搜索属性。 所述搜索模块还被配置为利用所述搜索属性对顺序访问存储元件的数据执行搜索操作,并且响应于所述搜索操作的执行,经由所述通信信道接口向所述主机数据处理系统提供搜索结果数据。
