    • An exemplary storage network and methods of operation are disclosed which make use of data consistent internal mirrors within a storage device. The exemplary storage network comprises first, second, and third storage cells, each of which include physical storage media and a storage controller that controls data operations with the storage media. The storage controllers are configured such that, in operation, write operations executed on the first storage cell are copied remotely in an ordered sequence to a cache memory in the second storage cell, write operations in the cache memory are mirrored onto a primary and secondary storage media in the second storage cell, and write operations mirrored to the secondary storage media are copied remotely to the third storage cell.
    • 公开了示例性存储网络和操作方法,其利用存储设备内的数据一致的内部反射镜。 示例性存储网络包括第一,第二和第三存储单元,每个存储单元包括物理存储介质和控制与存储介质的数据操作的存储控制器。 存储控制器被配置为使得在操作中,在第一存储单元上执行的写入操作以有序的顺序被复制到第二存储单元中的高速缓冲存储器中,高速缓冲存储器中的写入操作被镜像到主存储器和辅助存储器 第二存储单元中的介质以及镜像到辅助存储介质的写入操作被远程复制到第三存储单元。

    • A database system is capable of executing a database application that transfers a logical object in multiple fragments. The database system comprises a main storage site, a remote storage site, a main protocol executable on the main storage site, and a remote protocol executable on the remote storage site. The remote storage site is capable of linking to the main storage site and mirroring information stored in the main storage site. The remote storage site includes a storage and a cache sidefile divided into a plurality of array sidefile recordsets. The main protocol is capable of including information indicative of logical object fragment commencement and completion in the multiple fragment database application transfer. The remote protocol is capable of controlling the cache sidefile to cache the multiple fragments as received and to enable destaging of the logical object to the storage on receipt of all fragments.
    • 数据库系统能够执行以多个片段传送逻辑对象的数据库应用程序。 数据库系统包括主存储站点,远程存储站点,主存储站点上可执行的主协议以及远程存储站点上可执行的远程协议。 远程存储站点能够链接到主存储站点并镜像存储在主存储站点中的信息。 远程存储站点包括被分成多个阵列侧文件记录集的存储和缓存侧文件。 主协议能够在多片段数据库应用传输中包括指示逻辑对象片段开始和完成的信息。 远程协议能够控制高速缓存侧文件来缓存接收到的多个片段,并且在接收到所有片段时使逻辑对象能够到达存储器。

    • A subcool flow control valve useful in a refrigerant system includes an enclosure having a fluid flow pathway for a controlled fluid between an inlet and an outlet. A thermally conductive flexible wall forms a sealed cavity within the enclosure for carrying a controlling fluid. A metering orifice operable between the pathway and the outlet port controls an amount of metered fluid passing through the outlet port in response to movement of the flexible wall toward and away from the metering orifice in response to temperature changes of the controlled fluid transmitting temperature and thus pressure changes to the controlling fluid in the sealed cavity. Inverse thermal feedback means is formed as part of the valve for stabilizing valve operation thus providing means for transmitting a thermal signal from the metered controlled fluid back to the controlling fluid.
    • 可用于制冷剂系统的过冷流量控制阀包括具有用于入口和出口之间受控流体的流体流动通道的外壳。 导热柔性壁在外壳内形成用于承载控制流体的密封空腔。 响应于受控的流体传递温度的温度变化响应于柔性壁朝向和远离计量孔的移动而响应于受控流体传递温度的温度变化,可操作在路径和出口之间的计量孔口可控制通过出口的计量流体的量 对密封腔中的控制流体的压力变化。 逆热反馈装置形成为用于稳定阀操作的阀的一部分,从而提供用于将热信号从计量控制流体传送回控制流体的装置。

    • A data synchronization method (for a redundant data storage arrangement in which there are at least a primary storage entity and mirroring first and second remote storage entities in communication therewith, respectively, writes to the first and second remote storage entities being tracked via respective first and second sidefiles, the first and second storage entities having different levels of write-currency relative to each other) may include: comparing the first sidefile with the second sidefile; and updating writes stored at the second remote storage entity based upon the comparison of the first and second sidefiles.
    • 一种数据同步方法(对于冗余数据存储装置,其中存在至少一个主存储实体,并且分别与其通信的第一和第二远程存储实体镜像,分别经由各自的第一和第二远程存储实体对第一和第二远程存储实体进行跟踪) 第二侧文件,具有不同级别的写入货币的第一和第二存储实体相对于彼此)可以包括:将第一副文件与第二副文件进行比较; 以及基于所述第一和第二侧面文件的比较来更新存储在所述第二远程存储实体的写入。
