摘要： Methods and systems for a virtual environment are provided. A method includes receiving a packet from a first virtual machine at a virtual switch; determining if the packet is destined to a second virtual machine by comparing a destination address to a mapping data structure maintained by the virtual switch; transferring the packet to a first virtual function of a device assigned to the first virtual machine by directly mapping the first virtual function to the first virtual machine; the first virtual function initiating a direct memory access (DMA) operation to transfer the packet to the second virtual machine based on a logical memory address of the second virtual machine that is received from a second virtual function; and using the DMA operation to transfer the packet to the second virtual machine.

摘要： Methods and systems for processing task management requests are provided. A cache client adapter receives a task management request other than an abort for a logical storage object owned by a cache owner adapter and determines if there are any pending input/output (I/O) requests associated with the storage object. The cache client adapter sends an abort request to the cache owner adapter when there are pending I/O requests and sends the task management request directly to a controller that manages a storage device whose space is presented as the logical storage object; and sends only the task management request to the controller when there are no pending I/O requests for the logical storage object.

摘要： Network device and associated methods are provided. The network device includes a plurality of base-ports, each base-port coupled to a plurality of network links and each base-port includes a plurality of sub-ports configured to operate as independent ports for sending and receiving information. Each network link is coupled to a smoothing first in-first out (FIFO) memory module that is used to temporarily store information at a first clock rate and information is read from the smoothing FIFO at a second clock. A sub-port can include one network link or more than one network link for receiving information from another device. A controller module monitors the smoothing FIFO for each network link to insert or delete characters from each of the smoothing FIFO based on a sub-port configuration for maintaining an order in which information is received for the sub-port.

摘要： A system having an initiator adapter coupled to a computing system and communicating with a target adapter coupled to a target controller managing a plurality of storage devices is provided. The initiator adapter initiates an input/output (I/O) request for the target adapter; assigns an exchange identifier for processing the I/O request and embeds a cookie in the exchange identifier for performing a function. The target adapter then sends a response to the I/O request to the initiator adapter with the exchange identifier and the cookie; and the initiator adapter extracts the cookie from the exchange identifier received from the target adapter.
