Abstract: A first solid state drive (SSD) includes a built-in network interface device configured to communicate via a network fabric, and a second SSD includes a built-in network interface device configured to communicate via the network fabric. A connection is opened between the first SSD and the second SSD over the network fabric, where the first SSD is further communicatively coupled to the second SSD further over an interconnect associated with a host computer. The first SSD encapsulates a non-volatile memory over fabric (NVMe-oF) command to transfer data between the first SSD and the second SSD in a capsule and sends the capsule to the second SSD over the connection. The second SSD executes the NVMe command to transfer the data between the first SSD and the second SSD over the connection according to an NVMe-oF communication protocol and without transferring any of the data to the host computer.

Abstract: A network device has a packet input unit, a checking unit, and a discovery unit. The packet input unit is configured to receive ingress packets. The checking unit is configured to determine whether identifying characteristics of received ingress packets match stored identifying characteristics of a packet flow that is stored in a memory, to perform a network action when the identifying characteristic of the received ingress packet matches the stored identifying characteristic. The discovery unit is configured to intercept an egress packet received from the control plane processor, the egress packet corresponding to the received ingress packet, to determine one or more differences in selected portions of a header portion of the received ingress packet resulting from processing at the control plane processor, and to store in the memory a new network action based on the one or more differences.

Abstract: A network device has counters that are configured to generate for a plurality of byte positions in a specified portion of data packets, a count indicative of a correspondence of a value found at the byte position corresponding to a rule such that occurrences of predetermined byte values in the plurality of byte positions may be counted. A packet classifier is configured to receive from the counters a number of byte values corresponding to the rules and to classify data packets based on the analysis.
