    • In one embodiment of the invention, a utility may be installed (e.g., by a system administrator) on a storage system. The utility may read content units on the storage system that are stored in one data format, and convert the content units to a second data format. In one embodiment, in response to a read request for a content unit, a data format in which to return the content unit may be selected and the content unit may be returned in that data format. In another embodiment, mapping information may be created that specifies in which data format a content unit should be returned in response to a request for the content unit. The mapping information may be stored either on the storage system that stores the content unit, the computer requesting access to the content unit, or any other computer or device in the computer system.
    • 在本发明的一个实施例中,可以在存储系统上安装实用程序(例如由系统管理员)。 实用程序可以读取以一种数据格式存储的存储系统上的内容单元,并将内容单元转换为第二数据格式。 在一个实施例中,响应于对内容单元的读取请求,可以选择其中返回内容单元的数据格式,并且可以以该数据格式返回内容单元。 在另一个实施例中,可以创建映射信息,该映射信息指定响应于对内容单元的请求而应当返回内容单元的哪个数据格式。 映射信息可以存储在存储内容单元的存储系统上,请求访问内容单元的计算机或计算机系统中的任何其他计算机或设备。

    • Embodiments of the present invention are directed to a method and apparatus for receiving an input/output (I/O) request from a host computer that specifies an operation to be performed on a content addressable storage (CAS) system and determining which operation is specified by the request before receipt of the I/O request by a content addressable storage system. In another embodiment, an I/O request from a host computer is received by a first CAS which determines if the request is to be processed by another CAS system. When it is determined that the request is to be processed by another CAS system, the first CAS system may forward the request to the other CAS system. In another embodiment, an appliance receives an I/O request from a host computer to perform an operation that accesses a unit of content. The appliance may set up a communication session between the host and a CAS system so that the unit of content may be transmitted between the host and the CAS system without passing through the appliance.
    • 本发明的实施例涉及一种用于从主计算机接收指定要对内容可寻址存储(CAS)系统执行的操作并确定指定了哪个操作的输入/输出(I / O)请求的方法和装置 通过内容可寻址存储系统接收到I / O请求之前的请求。 在另一实施例中,来自主计算机的I / O请求由第一CAS接收,其确定该请求是否由另一CAS系统处理。 当确定请求由另一个CAS系统处理时,第一个CAS系统可以将该请求转发给另一个CAS系统。 在另一个实施例中,设备从主计算机接收I / O请求以执行访问内容单元的操作。 设备可以在主机和CAS系统之间建立通信会话,使得可以在主机和CAS系统之间传送内容单元而不通过设备。
