    • A system for managing data transfer using an operating system address space, the address space comprising a user space and a kernel space, the system comprising a data buffer in the kernel space and a control module for the data buffer in the user space, the system further comprising a network protocol handling module that receives an I/O request in the kernel space for performing an I/O operation on the data buffer. The network protocol handling module notifies the control module of the I/O request via an upper level protocol handling module. The control module maintains address pointers in the data buffer and informs the network protocol handling module of the buffer address at which the I/O operation is to be performed.
    • 一种用于使用操作系统地址空间管理数据传输的系统,所述地址空间包括用户空间和内核空间,所述系统包括所述内核空间中的数据缓冲器和所述用户空间中的所述数据缓冲器的控制模块,所述系统 还包括网络协议处理模块,其在所述内核空间中接收对所述数据缓冲器执行I / O操作的I / O请求。 网络协议处理模块通过上级协议处理模块向控制模块通知I / O请求。 控制模块维护数据缓冲区中的地址指针,并向网络协议处理模块通知执行I / O操作的缓冲区地址。

    • A controller, system, method and computer program for emulating one or more tape-based storage devices using non-tape based physical data storage media. The controller is adapted to generate a data set for indicating an available capacity of the one or more emulated tape-based storage devices, the data set includes capacity data for indicating a respective available capacity of the one or more emulated tape-based storage devices based on an available capacity of the non-tape-based physical data storage media. The controller is also adapted to provide access to data stored on the non-tape based physical data storage medium using tape-based media command and the data set, and to dynamically update the capacity data of the data set in response to a change in the available capacity of the non-tape-based physical data storage media.
