Abstract: Systems, methods, and related technologies for application-centric object storage and interfaces. In certain aspects, a processing device receives, from a first application, one or more requests with respect to a data object. The processing device processes the one or more requests to identify one or more substructures of the data object. Based on an identification of the one or more substructures of the data object, the processing device defines a storage structure for the data object. The processing device defines an interface through which the first application can provide data access commands to the data object as stored in the defined storage structure.

Abstract: A method or system of managing data with high granularity, comprises identifying data objects and an associated data management policy. The policy uses features and a common semantic to define a feature-based sequence of data management actions of a data management operation that varies for different objects depending on respective features. Features of the data objects are obtained and then used to associate a data management action with the object using the policy so that the object is managed individually according to its own features, thus achieving high granularity of data management precision and also high flexibility.

Abstract: A method for communication in a packet data network including a subnet containing multiple nodes having respective ports. The method includes assigning respective local identifiers to the ports in the subnet, such that each port receives a respective local identifier that is unique within the subnet to serve as an address for traffic within the subnet that is directed to the port. In addition to the local identifiers, respective port identifiers are assigned to the ports, such that at least one of the port identifiers is shared by a plurality of the ports, but not by all the ports, in the subnet. The plurality of the ports are addressed collectively using the at least one of the port identifiers.

Abstract: A computing method includes specifying a virtual computer system including at least one virtual or physical compute node, which produces data packets having respective source attributes. At least one Virtual Input-Output Connection (VIOC) that is uniquely associated with the values of the source attributes is defined. A policy specifying an operation to be performed with regard to the VIOC is defined. The virtual computer system is implemented on a physical computer system, which includes at least one physical packet switching element. The physical packet switching element is configured to identify the data packets whose source attributes have the values that are associated with the VIOC and to perform the operation on the identified data packets, so as to enforce the policy on the VIOC.

Abstract: A method for data storage includes configuring a driver program on a host computer to receive commands in accordance with a protocol defined for accessing local storage devices connected to a peripheral component interface bus of the host computer. When the driver program receives, from an application program running on the host computer a storage access command in accordance with the protocol, specifying a storage transaction, a remote direct memory access (RDMA) operation is performed by a network interface controller (NIC) connected to the host computer so as to execute the storage transaction via a network on a remote storage device.

Abstract: A data storage system includes a storage server, including non-volatile memory (NVM) and a server network interface controller (NIC), which couples the storage server to a network. A host computer includes a host central processing unit (CPU), a host memory and a host NIC, which couples the host computer to the network. The host computer runs a driver program that is configured to receive, from processes running on the host computer, commands in accordance with a protocol defined for accessing local storage devices connected to a peripheral component interface bus of the host computer, and upon receiving a storage access command in accordance with the protocol, to initiate a remote direct memory access (RDMA) operation to be performed by the host and server NICs so as to execute on the storage server, via the network, a storage transaction specified by the command.

Abstract: A network interface includes a host interface for communicating with a node, and circuitry which is configured to communicate with one or more other nodes over a communication network so as to carry out, jointly with one or more other nodes, a redundant storage operation that includes a redundancy calculation, including performing the redundancy calculation on behalf of the node.
