Abstract: A layered-infrastructure blockchain-based system for software license distribution includes a distributed cloud of blockchain full nodes. Each blockchain full node contains a blockchain data structure on which a complete set of license key transactions are recorded. The layered-infrastructure also includes a plurality of storage systems. Each respective storage system contains a blockchain light data structure on which only a subset of license key transactions associated with that respective storage system are recorded. A plurality of hosts connect to the plurality of storage systems. As the hosts connect to the storage systems, license key transactions are generated, such that the license key transactions that are recorded in the blockchain-based system for software license distribution are associated with the connection events between the plurality of hosts and the plurality of storage systems.

Abstract: An aspect of the present disclosure relates to establishing and controlling virtual network communications between storage arrays. In embodiments, Input/Output (IO) workloads received by a source device are monitored. IO operations of each IO workload to be transmitted to one or more target devices of a plurality of target devices can be identified. Transmissions of one or more of the identified IO operations can be controlled based on one or more characteristics of each identified IO operation.

Abstract: An aspect of the present disclosure relates to using at least one service-level objective (SLO) to control data communications between two or more devices over a network. In embodiments, a notification is received by a source device. The notification can include status information of at least one of a plurality of communication paths between the source device and a target device. A communications control technique can be performed based on the indicated status. The communications control technique can include prioritizing one or more data packets based on a data payload corresponding to each packet. The technique can also include controlling the transmission of one or more data packets based on each data packet's priority.
