Abstract: Systems and methods enable session sharing for session-based remote direct memory access (RDMA). Multiple queue pairs (QPs) can be added to a single session and/or session group where each of the QPs has a common remote. Systems and methods may query a session ID for an existing session group and then use the session ID with an add QP request to join additional QPs to an existing session. Newly added QPs may share one or more features with existing QPs of the session group, such as encryption parameters. Additionally, newly added QPs may be configured with different performance or quality of service requirements, thereby isolating performance, and permitting true scaling for high performance computing applications.

Abstract: Methods and systems provided herein involve extracting an input/output (I/O) operation from a packet received over an I/O pipeline, the I/O operation comprising either a read request to read data from at least one storage device or a write request to write data to the at least one storage device; determining that an address associated with the I/O operation exists in a lookup table that is provided for thin provisioning of the at least one storage device; performing one or more RAID calculations associated with the at least one storage device based on the address and the I/O operation; and accessing the at least one storage device to perform the I/O operation based on the one or more RAID calculations; and second processing component configured to carry out a second set of operations that occur when the address associated with the I/O operation does not exist in the lookup table.

Abstract: In one embodiment, a network device, including a network interface to receive packets over a packet data network, and a hierarchical policer to provide queue fairness for a plurality of network flows competing for access to a multiplex network receive queue, and including level one meters to label the received packets, a level two meter to receive at least some of the labeled packets and relabel the at least some labeled packets, and queueing logic add the packets labeled with a first label-type to the multiplex network receive queue and drop the packets labeled with a third label-type.

Abstract: A system includes a bus interface and circuitry. The bus interface is configured to communicate with an external device over a peripheral bus. The circuitry is configured to support a plurality of widgets that perform primitive operations used in implementing peripheral-bus devices, to receive a user-defined configuration, which specifies a user-defined peripheral-bus device as a configuration of one or more of the widgets, and to implement the user-defined peripheral-bus device toward the external device over the peripheral bus, in accordance with the user-defined configuration.
