    Abstract: Systems and methods for an interconnect layer send queue reservation system are provided. In one example, a method involves performing a transfer of data (e.g., an NVLog) from a storage system to a secondary storage system. A send queue having a fixed number of slots is maintained within an interconnect layer interposed between a file system and a Remote Direct Memory Access (RDMA) layer of the storage system. The interconnect layer implements an application programming interface (API) for the reservation system. A deadlock situation is avoided by, during a suspendable phase of a write transaction, making a reservation for slots within the send queue via the reservation system for the transfer of data. When the reservation is successful, the write transaction proceeds with a modify phase, during which the reservation is consumed and the interconnect layer is caused to perform an RDMA operation to carry out the transfer of data.

    Abstract: A method, non-transitory computer readable medium and storage server computing device that determines when a generated storage operation corresponds with one of a set of predefined storage operations. The storage operation is executed and a result of the execution of the storage operation is withheld from a file system, when the determining indicates that the storage operation corresponds with one of the set of predefined storage operations. A determination is made when a consistency point operation has completed. The result of the execution of the storage operation is presented to the file system, when the determining indicates that a consistency point operation has completed. This technology reduces the number of storage operations that are required to be journaled to maintain consistency of a file system, thereby reducing the runtime resources required to facilitate the journaling and replay resource required to replay the storage operations in a journal following a recovery.

    Abstract: Systems and methods for sharing a namespace of an ephemeral storage device by multiple consumers are provided. In an example, an NVMe driver of a virtual storage system deployed within a compute instance of a cloud environment facilitates sharing of the namespace by exposing an API through which the multiple consumers access an ephemeral storage device associated with the compute instance. During initialization processing performed by each consumer, for example, during boot processing of the virtual storage system, the consumers may share the namespace by reserving for their own use respective partitions within the namespace via the API and thereafter restrict their usage of the namespace to their respective partitions, thereby retaining the functionality provided by the multiple consumers when the host on which the compute instance is deployed has fewer ephemeral storage devices than consumers that rely on the availability of vNVRAM backed by ephemeral storage.

    Abstract: Systems and methods are described for a cross-site high availability distributed storage system. According to one embodiment, a computer implemented method includes providing a remote direct memory access (RDMA) request for a RDMA stream, and generating, with an interconnect (IC) layer of the first storage node, multiple IC channels and associated IC requests for the RDMA request. The method further includes mapping an IC channel to a group of multiple transport layer sessions to split data traffic of the IC channel into multiple packets for the group of multiple transport layer sessions using an IC transport layer of the first storage node and assigning, with the IC transport layer, a unique transaction identification (ID) to each IC request and assigning a different data offset to each packet of a transport layer session.
