  • Caching method and system based on cache cluster
    Patent number: 10469577
    Abstract: A caching method based on a cache cluster is provided, the method including determining a partition number of a caching partition corresponding to to-be-written data; querying, with a view service node according to the partition number, primary node information of the caching partition corresponding to the to-be-written data; receiving the primary node information that is of the caching partition corresponding to the to-be-written data and that is returned by a view service node, and sending a write request to a primary node of the caching partition corresponding to the to-be-written data; writing the to-be-written data into a local write-back cache according to the write request; and obtaining information about each secondary node of the caching partition corresponding to the to-be-written data from the view service node, and copying the to-be-written data to each secondary node of the caching partition corresponding to the to-be-written data.

  • Multi-protocol global namespace mechanism for network attached storage
    Patent number: 8527586
    Abstract: The present invention provides a system and method for abstracting multiple network attached storage (“NAS”) locations, providing a single global namespace and a single mount point that is protocol and location-independent. As a result, rather than identifying each NAS and file server by location, access is provided through a single transparent mechanism. In order to maintain transparency, the present invention provides a way to reconcile the different naming practices for different file server protocols.
