    Abstract: One or more techniques and/or systems are provided for interconnect failover between a primary storage controller and a secondary storage controller. The secondary storage controller may be configured as a backup or failover storage controller for the primary storage controller in the event the primary storage controller fails. Data and/or metadata describing the data (e.g., data and/or metadata stored within a write cache) may be mirrored from the primary storage controller to the secondary storage controller over one or more interconnect paths. Responsive to identifying a failover trigger for a failed interconnect path, the secondary storage controller is instructed to fence (e.g., block) I/O operations from the failed interconnect path. Streams of data and/or metadata that were affected by the failure may be instructed to transmit such data and/or metadata over one or more non-failed interconnect paths to the secondary storage controller during failover of the failed interconnect path.

    Abstract: Systems and methods which provide for managing multiple mirror resources in a storage distribution network are provided. In some embodiments, a system provides for both high availability and disaster recovery functionality at different mirroring locations. Other embodiments may provide for multiple high availability and/or multiple disaster recovery mirror resources. These mirror resources are operated in a heterogeneous manner in the sense that each have its own transport, protocol, and the like, but are configured function cooperatively or as a single mirror with respect to mirroring a primary node. Embodiments may provide for the mirroring and resynchronization of mirrored resources in the event of a communication loss with a particular resource without ceasing the mirroring operations to other resources.

    Abstract: One or more techniques and/or systems are provided for mirroring a caching log data structure from a primary storage controller to a secondary storage controller over multiple interconnect paths. The secondary storage controller may be configured as a backup or failover storage controller for the primary storage controller in the event the primary storage controller fails. Data and/or metadata describing the data may be mirrored from the primary storage controller to the secondary storage controller over one or more interconnect paths. The caching log data structure may be parsed into a plurality of streams. The streams may be assigned to interconnect paths between the primary storage controller and the secondary storage controller. A data ordering rule is enforced during mirroring of storage information of the streams across the interconnect paths (e.g., the secondary storage controller is to receive data in the order it was sent by respective streams).

    Abstract translation: 提供了一个或多个技术和/或系统,用于通过多个互连路径将缓存日志数据结构从主存储控制器镜像到辅助存储控制器。 在主存储控制器发生故障的情况下,辅助存储控制器可以被配置为主存储控制器的备份或故障转移存储控制器。 可以通过一个或多个互连路径将描述数据的数据和/或元数据从主存储控制器镜像到辅助存储控制器。 缓存日志数据结构可以被解析成多个流。 可以将流分配给主存储控制器和辅助存储控制器之间的互连路径。 在跨互连路径的流的存储信息的镜像期间执行数据排序规则(例如,辅助存储控制器将按照由相应的流发送的顺序来接收数据)。

    Abstract: Systems and methods which provide for managing multiple minor resources in a storage distribution network are provided. In some embodiments, a system provides for both high availability and disaster recovery functionality at different mirroring locations. Other embodiments may provide for multiple high availability and/or multiple disaster recovery mirror resources. These mirror resources are operated in a heterogeneous manner in the sense that each have its own transport, protocol, and the like, but are configured function cooperatively or as a single minor with respect to minoring a primary node. Embodiments may provide for the minoring and resynchronization of mirrored resources in the event of a communication loss with a particular resource without ceasing the minoring operations to other resources.
