Abstract: A method, non-transitory computer readable medium and host computing device that stores, by a first virtual storage controller, a plurality of received transactions in a transaction log in an in-memory storage device. The first virtual storage controller is monitored and a determination is made when a failure of the first virtual storage controller has occurred based on the monitoring. When the failure of the first virtual storage controller is determined to have occurred, at least one storage volume previously assigned to the first virtual storage controller is remapped to be assigned to a second virtual storage controller. Additionally, the second virtual storage controller retrieves at least one of the transactions from the transaction log in the in-memory storage device and replays at least one of the transactions.

Abstract: One or more techniques and/or systems are provided for virtual machine rebooting. A host machine may host a virtual machine. Virtual machine reboot information, used to reboot the virtual machine in the event of a failure or restart of the virtual machine, may be identified (e.g., file system metadata buffers, a virtual non-volatile random access memory log, user data buffers, and/or data used to reboot the virtual machine such as to perform a reboot mounting operation and/or a reboot replay operation of a volume of data associated with the virtual machine). The virtual machine reboot information may be cached within relatively fast host memory of the host machine (e.g., instead of merely within a relatively slower hard drive or other storage device). In this way, the cached virtual machine reboot information may be quickly retrieved so that the virtual machine may be rebooted in a relatively shorter amount of time.

Abstract: A live non-volatile (NV) replay technique enables a partner node to efficiently takeover a failed node of a high-availability pair in a multi-node storage cluster by dynamically replaying operations synchronously logged in a non-volatile random access memory (NVRAM) of the partner node, while also providing high performance during normal operation. Dynamic live replay may be effected through interpretation of metadata describing the logged operations. The metadata may specify a location and type of each logged operation within a partner portion of the NVRAM, as well as any dependency among the logged operation and any other logged operations that would impose an ordering constraint. During normal operation, the partner node may consult the metadata to identify dependent logged operations and dynamically replay those operations to satisfy one or more requests. Upon failure of the node, the partner node may replay, in parallel, those logged operations having no imposed ordering constraint, thereby reducing time needed to complete takeover of the failed node.
Abstract translation: 实时非易失性（NV）重播技术使得伙伴节点能够通过动态重放同步记录在非易失性随机存取存储器（NVRAM）中的操作来有效地接管多节点存储集群中的高可用性对的故障节点， 的合作伙伴节点，同时在正常运行期间也提供高性能。 可以通过解释描述记录的操作的元数据来实现动态实时重放。 元数据可以指定NVRAM的伙伴部分内的每个记录操作的位置和类型，以及记录的操作和将强制排序约束的任何其他记录操作之间的任何依赖关系。 在正常操作期间，伙伴节点可以查阅元数据以识别相关的记录操作，并动态地重放那些操作以满足一个或多个请求。 在节点发生故障时，伙伴节点可以并行地重播没有施加的排序约束的那些记录的操作，从而减少完成对故障节点的接管所需的时间。

Abstract: A method, apparatus, and system of presentation of a read-only clone Logical Unit Number (LUN) to a host device as a snapshot of a parent LUN are disclosed. In one embodiment, a method includes generating a read-write clone LUN of a parent LUN and coalescing an identical data instance of the read-write clone LUN and the parent LUN in a data block of a volume of a storage system. A block transfer protocol layer is modified to refer the read-write clone LUN as a read-only clone LUN, according to the embodiment. Furthermore, according to the embodiment, the read-only clone LUN is presented to a host device as a snapshot of the parent LUN.

Abstract: A distributed control protocol dynamically establishes high availability (HA) partner relationships for nodes in a cluster. A HA partner relationship may be established by copying (mirroring) information maintained in a non-volatile random access memory (NVRAM) of a node over a HA interconnect to the NVRAM of a partner node in the cluster. The distributed control protocol leverages a Cluster Liveliness and Availability Manager (CLAM) utility of a storage operating system executing on the nodes to rebalance NVRAM mirroring and alter HA partner relationships of the nodes in the cluster. The CLAM utility is configured to maintain various cluster related issues, such as CLAM quorum events, addition or subtraction of a node in the cluster and other changes in configuration of the cluster. Notably, the CLAM utility is an event based manager that implements the control protocol to keep the nodes informed of any cluster changes through event generation and propagation.

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.
