Abstract: Technology is provided for selecting a master node of a node group in a storage system. The technology can gather data regarding visibility of one or more storage devices of the storage system to one or more active nodes of the node group, determine a maximum visibility value for the node group and selecting an active node with associated visibility value equal to the maximum visibility value as the master node of the node group.

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。
