Abstract: A data storage system that includes first and second controllers is provided. Data is mirrored from one controller to the other controller according to different steps depending on the amount of data to be mirrored. When the data to be mirrored is less than or equal to a predetermined number of bytes, one less interrupt is generated than when the data to be mirrored is greater than the predetermined number of bits.
Abstract translation: 提供了包括第一和第二控制器的数据存储系统。 根据不同的步骤，根据要镜像的数据量，将数据从一个控制器镜像到另一个控制器。 当要镜像的数据小于或等于预定数量的字节时，比要镜像的数据大于预定位数时产生一个以上的中断。

Abstract: A network storage controller for transferring data between a host computer and a storage device, such as a redundant array of inexpensive disks (RAID), is disclosed. The network storage controller includes at least one channel interface module which is adapted to be connected to the host computer and storage device. The channel interface module is connected to a passive backplane, and selectively transfers data between the host computer and storage device and the passive backplane. The network storage controller also includes at least one controller management module, attached to the passive backplane. The controller management module communicates with the channel interface module via the passive backplane, and processes and temporarily stores data received from the host computer or storage device. In applications where redundancy is required, at least two controller management modules and at least two channel interface modules may be used. The controller management modules may mirror data between one another using the passive backplane and a shared communication path on the channel interface modules, thereby substantially avoiding the use of host or disk channels to mirror data. The channel interface modules are operable to connect the host computer or storage device to one or more controller memory modules. The controller memory modules may include a DMA engine to facilitate the transfer of mirrored data.

Abstract: A network storage controller (100) for transferring data between a host computer and a storage device, such as a redundant array of inexpensive disks (RAI), is disclosed. The network storage controller (100) includes at least one channel interface module (136, 140) which is adapted to be connected to the host computer and storage device. The channel interface module (136, 140) is connected to a passive backplane (116), and selectively transfers data between the host computer and storage device and the passive backplane (116). The network storage controller (100) also includes at least one controller management module (104, 108), attached to the passive backplane (116). The controller management module (104, 108) communicates with the channel interface module (136, 140) via the passive backplane (116), and processes and temporarily stores data received from the host computer or storage device. In applications where redundancy is required, at least two controller management modules (104, 108) and at least two channel interface modules (136, 140) may be used. The controller management modules (104, 108) may mirror data between one another using the passive backplane (116) and a shared communication path on the channel interface modules (136, 140), thereby substantially avoiding the use of host or disk channels to mirror data. The channel interface modules (136, 140) are operable to connect the host computer or storage device to one or more controller memory modules (104, 108). The controller management modules (104, 108) may include a DMA engine to facilitate the transfer of mirrored data.
