    Abstract: Technology is disclosed for recovering I/O modules in a storage system using in-band alternate control path (ACP) architecture ("the technology"). The technology enables a storage server to transmit control commands, e.g., for recovering an I/O module, to the I/O module over a data path that is typically used to transmit data commands. The control commands are typically transmitted using ACP that is separate from the data path. By enabling transmission of control commands over the data path, the technology eliminates the need for separate medium for ACP, at least in part, to transmit the control commands. The technology can be implemented in a pure in-band ACP mode, which supports recovering an I/O module of a storage shelf in which at least one I/O module is responsive, and/or in a mixed in-band ACP mode, which supports recovery of I/O modules of a storage shelf in which all I/O modules are non responsive.

    Abstract translation: 公开了用于使用带内替代控制路径(ACP)架构(“该技术”)在存储系统中恢复I / O模块的技术。 该技术使得存储服务器能够通过通常用于发送数据命令的数据路径向I / O模块发送例如用于恢复I / O模块的控制命令。 控制命令通常使用与数据路径分离的ACP传输。 通过使数据路径上的控制命令能够传输,该技术消除了对于ACP的单独介质的需要,至少部分地传送控制命令。 该技术可以以纯带内ACP模式实现,其支持恢复其中至少一个I / O模块响应的存储架的I / O模块和/或混合带内ACP模式, 其支持恢复所有I / O模块不响应的存储架的I / O模块。

    Abstract: A storage system includes a RAID adapter, disk array switches, sub-processors, and hard disk drives (HDDs). A disk-related operation is initiated in the RAID adapter. The RAID adapter dispatches a command to a disk array processor (or sub-processor) in an enclosure for the processor to perform the operation on one or more drives. The adapter may dispatch the command to a processor in a single enclosure through a disk array switch or to processors in multiple enclosures through switches in the upstream enclosures. The adapter is then free to perform other functions. The processor commences the specified operation on one or more selected drives, either sequentially one at a time or sequentially more than one (or all) at a time. Upon completion of the operation, the results are transmitted by the processor and received by the adapter. Thus, by offloading the task to the distributed sub-processors, the burden on the RAID adapter is significantly reduced, system bandwidth usage is reduced, and access to other drives within the enclosure (as well as within other enclosures) may be maintained. Tasks which may be offloaded in such a manner include, but are not limited to, drive firmware updating, drive scrubbing and secure data erasure.

    Abstract translation: 存储系统包括RAID适配器,磁盘阵列交换机,子处理器和硬盘驱动器(HDD)。 磁盘相关操作在RAID适配器中启动。 RAID适配器将命令分配给机箱中的磁盘阵列处理器(或子处理器),以便处理器对一个或多个驱动器执行操作。 适配器可以通过磁盘阵列交换机将命令分派到单个机柜中的处理器,或通过上游机箱中的开关将命令分配到多个机箱中的处理器。 然后适配器可以自由执行其他功能。 处理器在一个或多个选定的驱动器上开始指定的操作,一次一个依次依次执行,或者一次连续执行多个(或全部)。 操作完成后,结果由处理器传送并由适配器接收。 因此,通过将任务卸载到分布式子处理器,RAID适配器的负担显着降低,减少了系统带宽使用,并且可以维护对外壳(以及其他机箱内)的其他驱动器的访问。 可以以这种方式卸载的任务包括但不限于驱动固件更新,驱动器擦除和安全数据擦除。

    Abstract: Network data storage systems and methods allow computers reading and writing data at a plurality of data centers separated by, potentially, large distances to replicate data between sites such that the data is protected from failures, including complete Site failures, while not allowing network latency to significantly impede the performance of read or write operations. Continued access to all data is provided even after a single failure of any component of the system or after any complete failure of all equipment located at any single geographic region or any failure that isolates access to any single geographic region. Write data is replicated synchronously from Active Sites, e.g., sites where servers are writing data to storage resources, to Protection Sites located sufficiently close to Active Sites such that network latency will not significantly impact performance, but sufficiently far apart such that a regional disaster is unlikely to affect both sites. Write data is then asynchronously copied to other sites, potentially including one or more Active sites, located at greater distances.

    Abstract translation: 网络数据存储系统和方法允许计算机在多个数据中心读取和写入数据,这些数据中心可能距离很远,以便在站点之间复制数据,从而保护数据免受故障,包括完整的站点故障,同时不允许网络延迟 显着阻碍了读写操作的执行。 即使在系统的任何组件发生单一故障之后或者位于任何单个地理区域的所有设备发生任何完全故障或者任何将访问隔离在任何单一地理区域的故障之后,仍可继续访问所有数据。 写入数据从Active Sites(例如,服务器正在将数据写入存储资源的站点)同步复制到位于与Active Sites紧密相连的保护站点,以便网络延迟不会对性能造成重大影响,但区域灾难相当遥远 不太可能影响两个网站。 然后将写入数据异步复制到其他站点,可能包括位于更远距离的一个或多个活动站点。

    Abstract: One embodiment of the present invention is an integrated circuit implementing a storage-shelf router (1102), used in combination with path controller cards (1110) and optionally with other storage-shelf routers (1104), to interconnect SA' disks (1108) within a storage shelf (1100) or disk array to a high-bandwidth communications medium, such as an FC arbitrated loop (1008). When two, four, six, or eight or more storage-shelf routers are used within a storage shelf, and tl interconnections between the storage-shelf routers, disk drives, and external communications media are properly designed and configured, the resulting storage shelf constitutes a discrete, highly-available component that may be included in a disk array or in other types of electronic devices. The storage-shelf router features a disk-drive adaptation layer (3604) that allows a storage-shelf router to interface to, and manage, any of many different types of disk drives (3608-3611). The disk-drive adaptation layer includes a disk-profile table (3902) and associated firmware logic.
