  • Adaptive namespaces for multipath redundancy in cluster based computing systems
    Patent number: 11226753
    Abstract: Methods, systems, and apparatuses for a high availability (HA) storage cluster comprising a switch, a set of storage resources, and a set of nodes. Each node includes an HA module. The HA module maintains a real storage object representing a storage resource that provides an interface for accessing the storage resource. The HA module maintains a ghost storage object corresponding to the real storage object. The ghost storage object is configured to return an error in response to a call to the interface when the command is an I/O command and return a valid path when the command is a discovery command, connect command, or namespace ID command. When the node owns the storage resource, the interface of the real storage object is called to execute the command. Otherwise, the interface of the ghost storage object is called to respond to the command.

  • Systems and methods for accessing non-volatile memory and write acceleration cache
    Patent number: 10831650
    Abstract: Embodiment of a storage stack are disclosed whereby increased performance and other technical improvements are achieved by an application requesting access (e.g., asynchronously) to an address, returning a buffer, and the application issuing a buffer release when the operation is complete.

  • Adaptive Namespaces for Multipath Redundancy in Cluster Based Computing Systems
    Publication number: 20190354302
    Abstract: Systems and methods for storage clusters and nodes thereof are disclosed. Embodiments may utilize an adaptive scheme to dynamically reconfigure namespaces based on the state of the storage cluster to support multipath redundancy in the storage cluster.
