  • Systems and methods for distributing cache space
    Patent number: 10452553
    Abstract: The disclosed computer-implemented method for distributing cache space may include (i) identifying workloads that make input/output requests to a storage system that comprises a cache that stores a copy of data recently written to the storage system, (ii) calculating a proportion of the cache that is occupied by data written to the cache by a workload, (iii) determining that the proportion of the cache that is occupied by the data written to the cache by the workload is disproportionate, and (iv) limiting the volume of input/output requests from workload that will be accepted by the storage system in response to determining that the proportion of the cache that is occupied by the data written to the cache by the workload is disproportionate. Various other methods, systems, and computer-readable media are also disclosed.

  • System and method for creating snapshots in openflame environment
    Patent number: 10191879
    Abstract: A method for creating snapshots and backups in a virtual computing environment is provided. The method includes writing application output of an application spanning one or more virtual machines as an application consistency group to a writeback cache, wherein the one or more virtual machines are implemented using one or more compute nodes and wherein the writeback cache is implemented in direct attached storage in the one or more compute nodes. The method includes pausing I/O (input/output) operations of the application and marking the pausing, in the writeback cache. The method includes resuming the I/O operations of the application, after the marking and dumping data, according to the marking, from the writeback cache to a data node, as a snapshot.
