摘要： A method of implementing a logical unit reset across a plurality of interfaces in a distributed storage system, comprising: initiating a session for implementing the logical unit reset across the plurality of interfaces in response to receiving at a central controller a logical unit reset command from an originator interface, and writing session-data including an indication that the originator interface implemented the respective logical unit reset locally; communicating a logical unit reset command from the central controller to each interface other than the originator interface; updating the session data in response to receiving an indication from an interface that the logical unit was successfully reset locally and when each one of the plurality of interfaces implemented the logical unit reset locally, communicating a success response to each one of the plurality of interfaces.

摘要： A system and method for accelerating input/output (IO) access operation on a virtual machine, The method comprises providing a smart IO device that includes an unrestricted command queue (CQ) and a plurality of restricted CQs and allowing a guest domain to directly configure and control IO resources through a respective restricted CQ, the IO resources allocated to the guest domain. In preferred embodiments, the allocation of IO resources to each guest domain is performed by a privileged virtual switching element. In some embodiments, the smart IO device is a HCA and the privileged virtual switching element is a Hypervisor.

摘要： Systems and methods for failure monitoring in a storage system. In some cases, a failed entity is detected based on an analysis of at least the indications obtained in return for input/output commands sent to multiple entities in the storage system. In some of these cases, it is also determined whether the failure is enduring or transient.

摘要： A method and system for digital communication wherein nodes exchange messages at a first data rate in order to coordinate testing at a second, higher data rate. After testing is completed, the nodes exchange test results at the first data rate, and if conditions are satisfactory for operation at the second data rate user data are transmitted at the second data rate. Otherwise, user data are transmitted at the first data rate.

摘要： A method for preventing deadlock in communication between a host software application and a network interface card (NIC), comprises writing a doorbell associated with at least one descriptor having a descriptor context to a buffer in the NIC, dropping at least one doorbell from the buffer if the buffer is full, thereby allowing a write of a new doorbell to the buffer, and recovering each dropped doorbell for further execution of descriptors associated with this doorbell. The descriptor execution is in order of posting by the application to the NIC. A system implementing the method comprises a doorbell drop mechanism and a doorbell recovery mechanism.

摘要： A network interface adapter includes a network interface, coupled to send and receive data packets over a network and a host interface, for coupling to a host processor and to a system memory associated therewith. The system memory contains context information with respect to a plurality of transport service instances used to send and receive the data packets over the network, each of the data packets belonging to a respective one of the service instances. Packet processing circuitry, coupled between the network interface and the host interface, processes the data packets using the context information of the respective service instances. A cache memory associated with the packet processing circuitry is coupled to load from the system memory and store the context information of the respective transport service instances for the data packets being processed by the packet processing circuitry.
