摘要： Machine implemented methods and systems for writing data at a storage device are provided. A write command from an initiator adapter is received at a target adapter interfacing with a target controller for writing data to the storage device; where the write command includes information regarding a virtual logical unit number (LUN) for writing data in response to the write command. The target controller uses an indicator to notify the target adapter to process the write command and provides information regarding a designated LUN for the storage device where data is to be written at the storage device in response to the write command. Thereafter, the target adapter sends a response to the initiator adapter that it is ready to receive data and issues a write command for the storage device at the same time.

摘要： Systems and methods for storage operations are provided. As an example, a method includes configuring a non-volatile memory of a network device to be used as a storage device for storing data for an application; generating a logical storage object for the application for using storage space at the non-volatile memory of the network device to store data for the application, where the network device creates a unique identifier for the logical storage object; identifying the logical storage object as a mirror logical storage object such that data written at the non-volatile memory device is mirrored by another network device operating as a peer to the network device; providing the unique identifier to the other network device for generating a mirror logical storage object for mirroring data that is stored at the non-volatile memory; receiving a request at the network device for writing data to the non-volatile storage object; writing data at the non-volatile memory of the network device when the request identifies the network device; and mirroring the data at the other network device, when the request indicates that the data needs to be mirrored.

摘要： Methods and systems for transmitting information are provided. A threshold message size is configured to determine when an application executed by a computing system can send a latency message identifying a memory location from where a device can procure a payload for transmission to a destination. The computing system sends a latency message to the device, where the latency message includes the memory location, a transfer size and an indicator indicating if the application wants a completion status after the latency message is processed. The computing system stores connection information at a location dedicated to the application that sends the latency message. The device transmits the payload to the destination; and posts a completion status, where the device posts the completion status at a completion queue associated with the application with information that enables the application to determine whether other latency messages can be posted.

摘要： Methods and systems for efficiently processing input/output requests are provided. A network interface card (NIC) is coupled to a storage device via a peripheral link and accessible to a processor of a computing device executing instructions out of a memory device. The NIC is configured to receive a read/write request to read/write data; translate the read/write request to a storage device protocol used by the storage device coupled to the NIC; notify the storage device of the read/write request, without using the processor of the computing device, where the storage device reads/writes the data and notifies the NIC; and then the NIC prepares a response to the read/write request without having to use the processor of the computing device.

摘要： Methods and systems for optimizing data structures to efficiently control network data transfers are provided. For example, the method includes determining common key type sets from a plurality of network processing rules; creating one or more hash data structures using the most common key type sets; programming network processing rules that use the most common key type sets into the one or more hash data structures; programming remaining network processing rules into a content addressable memory (CAM); and using the one or more hash data structures and the CAM to find an appropriate network processing rule to process a network packet.

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.
