摘要： Certain aspects of a method for iSCSI boot may include loading boot BIOS code from a host bus adapter or a network interface controller (NIC) by an iSCSI client device. A connection may be established to an iSCSI target by the iSCSI client device after loading the boot BIOS code. The boot BIOS code may be chained to at least one interrupt handler over iSCSI protocol. An operating system may be remotely booted from the iSCSI target by the iSCSI client device based on chaining the interrupt handler. An Internet protocol (IP) address and/or location of the iSCSI target may be received. At least one iSCSI connection may be initiated to the iSCSI target based on chaining at least one interrupt handler. The iSCSI target may be booted in real mode if at least one master boot record is located in the memory.

摘要： Certain embodiments of the invention may be found in a method and system for performing SCSI read operations with a CRC via a TCP offload engine. Aspects of the method may comprise receiving an iSCSI read command from an initiator. Data may be fetched from a buffer based on the received iSCSI read command. The fetched data may be zero copied from the buffer to the initiator and a TCP sequence may be retransmitted to the initiator. A digest value may be calculated, which may be communicated to the initiator. An accumulated digest value stored in a temporary buffer may be utilized to calculate a final digest value, if the buffer is posted. The retransmitted TCP sequence may be processed and the fetched data may be zero copied into an iSCSI buffer, if the buffer is posted. The calculated final digest value may be communicated to the initiator.

摘要： A method and system for handling received out-of-order network data using generic buffers for non-posting TCP applications is disclosed. When incoming out-of-order data is received and there is no application buffer posted, a TCP data placement may notify a TCP reassembler to terminate a current generic buffer, allocate a new current generic buffer, and DMA the incoming data into the new current generic buffer. The TCP data placement may notify the TCP reassembler the starting TCP sequence number and the length of the new current generic buffer. Moreover, the TCP data placement may add entries into a TCP out-of-order table when the incoming data creates a new disjoint area. The TCP data placement may adjust an existing disjoint area to reflect any updates. When a TCP application allocates or posts a buffer, then the TCP reassembler may copy data from a linked list of generic buffers into posted buffers.

At least a portion of the incoming data may be stored in the allocated generic buffer if the TCP application buffer is unable to accommodate the incoming data. The method may further determining whether the incoming data for the TCP connection transferred to the posted generic buffer is in sequence and ordering the incoming data based on a sequence number if the incoming data is out of sequence.

摘要： A method for processing network data includes collecting by a network interface controller (NIC), a plurality of transmit (TX) buffer indicators into a plurality of priority lists of connections. Each of the plurality of TX buffer indicators identifies transmit-ready data located externally to the NIC and not previously received by the NIC. One or more of the plurality of TX buffer indicators may be selected. The identified transmit-ready data may be retrieved into the NIC based on the selected one or more of the plurality of TX buffer indicators. At least a portion of the identified transmit-ready data may be transmitted. Each of the plurality of priority lists may be generated based on a particular connection priority characteristic and a particular connection type. The identified transmit-ready data may be associated with the same connection priority characteristic and the same connection type.
