Abstract: A method, non-transitory computer readable medium, and storage controller computing device that establishes an application interface and a source interface to a programmable switch. A flow table of the programmable switch is updated to insert routing actions associated with the application and source interfaces.Next, when an application request received from an application is locally serviceable is determined. When the determination indicates the application request is not locally serviceable, a migration request for data associated with the application request is sent to the programmable switch from the source interface and a destination address of a source storage server is used. Additionally, a migration response to the migration request including the data from the source storage server is received from the source interface. The data is then stored locally in a destination storage server and thereby is migrated from the source storage server.

Abstract: Example embodiments provide various techniques for securing communications within a group of entities. In one example method, a request from an entity to join the group is received and a signed, digital certificate associated with the entity is accessed. Here, the signed, digital certificate is signed with a group private key that is associated with a certification authority for the group. The signed, digital certificate is added to a group roster, and this addition is to admit the entity into the group. The group roster with the signed, digital certificate is itself signed with the group private key and distributed to the group, which includes the entity that transmitted the request. Communication to the entity is then encrypted using the signed, digital certificate included in the group roster.

Abstract: One or more techniques and/or systems are provided for multicast transport configuration, for multicast transport, and/or for fault policy implementation. In an example, a multicast component may receive a data copy request from an application to copy data to multiple destinations. A scheduler component may create a transport schedule specifying an order with which to facilitate data copy operations across transports, such as heterogeneous transports, to the destinations. A dispatcher component may apply application specified transport modifiers to the data copy operations (e.g., a modification to a quality of service for a transport). The dispatcher component may facilitate the data copy operations and provide operation result information to a policy agent. The policy agent may provide notifications of data copy operation statuses from the operation result information and/or may implement a fault policy (e.g., a retry on a different transport) for a data copy operation that experienced a fault.

Abstract: Methods and systems for dynamic hashing in cache sub-systems are provided. The method includes analyzing a plurality of input/output (I/O) requests for determining a pattern indicating if the I/O requests are random or sequential; and using the pattern for dynamically changing a first input to a second input for computing a hash index value by a hashing function that is used to index into a hashing data structure to look up a cache block to cache an I/O request to read or write data, where for random I/O requests, a segment size is the first input to a hashing function to compute a first hash index value and for sequential I/O requests, a stripe size is used as the second input for computing a second hash index value.

Abstract: This disclosure uses both an administrative thread and multiple worker threads (N) to process the LUN on-lining work in parallel at both the volume level and the LUN level. When the administrative thread receives the message to start the initialization, the administrative thread assigns the work for reading the VTOC information for the LUNs in a volume to one or more worker threads and moves on to perform additional initialization tasks. N worker threads work on N volumes in parallel. These worker threads then independently send messages (e.g., asynchronous messages) to the file system layer, and once the file system layer is done loading the required buffers, the file system layer sends replies back to the administrative thread. The administrative thread then again assigns work to the worker threads to finally bring the LUNs on-line.

Abstract translation: 本公开使用管理线程和多个工作线程（N）在卷级别和LUN级别并行处理LUN上线工作。 当管理线程接收到消息以开始初始化时，管理线程将将卷中的LUN的VTOC信息分配给一个或多个工作线程并继续执行其他初始化任务。 N个工作线程并行处理N个卷。 这些工作线程然后独立地向文件系统层发送消息（例如，异步消息），一旦文件系统层完成加载所需的缓冲区，则文件系统层将回复发送回管理线程。 然后，管理线程再次将工作分配给工作线程，以最终使LUN在线。

Abstract: Systems and methods herein are operable to simultaneously mirror data to a plurality of mirror partner nodes. In embodiments, a mirror client may be unaware of the number of mirror partner nodes and/or the location of the plurality of mirror partner nodes, and issue a single mirror command requesting initiation of a mirror operation. An interconnect layer may receive the single mirror command and split the mirror command into a plurality of mirror instances, one for each mirror node partner, wherein the mirror instances may be simultaneously launched. After the plurality of mirror operations has begun, the interconnect layer may manage completion reports indicating the completion status of respective mirror operations, and send a single return to the mirror client indicating whether the mirror command succeeded.

Abstract translation: 这里的系统和方法可操作以将数据同时镜像到多个镜像伙伴节点。 在实施例中，镜像客户端可能不知道镜像伙伴节点的数量和/或多个镜像伙伴节点的位置，并且发出请求启动镜像操作的单个镜像命令。 互连层可以接收单个镜像命令，并将镜像命令拆分成多个镜像实例，每个镜像镜像实例一个，每个镜像节点伙伴可以同时启动镜像实例。 在多个镜像操作开始之后，互连层可以管理指示相应镜像操作的完成状态的完成报告，并且向镜像客户端发送指示镜像命令是否成功的单个返回。

Abstract: Atomic write operations for storage devices are implemented by maintaining the data that would be overwritten in the cache until the write operation completes. After the write operation completes, including generating any related metadata, a checkpoint is created. After the checkpoint is created, the old data is discarded and the new data becomes the current data for the affected storage locations. If an interruption occurs prior to the creation of the checkpoint, the old data is recovered and any new is discarded. If an interruption occurs after the creation of the checkpoint, any remaining old data is discarded and the new data becomes the current data. Write logs that indicate the locations affected by in progress write operation are used in some implementations. If neither all of the new data nor all of the old data is recoverable, a predetermined pattern can be written into the affected locations.

Abstract translation: 存储设备的原子写入操作通过维护在缓存中被覆盖的数据直到写入操作完成来实现。 写操作完成后，包括生成任何相关的元数据，将创建一个检查点。 创建检查点后，旧数据将被丢弃，新数据将成为受影响存储位置的当前数据。 如果在创建检查点之前发生中断，则恢复旧数据，并丢弃任何新数据。 如果在创建检查点后发生中断，则丢弃任何剩余的旧数据，并将新数据变为当前数据。 在一些实现中使用写入指示在进行中写入操作影响的位置的日志。 如果既不能全部新数据也不能恢复旧数据，则可以将预定模式写入受影响的位置。

Abstract: System and method for remotely performing a power cycle operation for a storage shelf of a storage server using a control path independent of a data path used for processing I/O requests is provided. The storage server maintains a data structure for storing information regarding a state of a plurality of power latches that are used to control power for the storage shelf having an alternate control path module for receiving control commands via the control path. Depending on the state of the plurality of power latches, the storage server sends one or more commands to the alternate control path module to turn off power to the storage shelf during a power cycle operation. When the power shelf is powered off, the storage server waits for a certain duration and then sends one or more power on commands to the alternate control path module to power on the storage shelf.
