Problems solved by technology
[0003] However, under the requirement of transmission speed, the burden of system processing capacity caused by the data transmission protocol should not be too heavy
Because the iSCSI protocol is based on the TCP / IP communication protocol, and it is connected to the SCSI (Small Computer Systems Interface) interface, if both the iSCSI and TCP / IP communication protocols are executed by the host processor, then the Under the requirements of high-speed storage network and large amount of data transmission, it can be seen that the host processor will consume too much processing power on data transmission, so it is necessary to think about how to reduce the processing burden of the host

The invention discloses a storage system of an Internet small computer system interface for accelerating a login request of the Internet small computer system interface. The storage system comprises an initiator and a destination; the initiator proposes the login request so as to establish a data transmission channel; the destination receives the login request and establishes the data transmission channel between the destination and the initiator; and the destination comprises a user state module, a kernel module and a network card. The user state module carries out an interactive negotiationauthentication process and generates a packet setting request according to the login request; the kernel module establishes destination environment information according to the packet setting requestso as to record parameters of the packet setting request of the user state module; the network card transmits an access request to the initiator according to the target environment information; and when the initiator responds to a full-characteristic stage request to the destination, the full-characteristic stage request is processed by the network card.
Description
technical field [0001] The present invention relates to an Internet Small Computer Interface (iSCSI) storage system, in particular to an Internet Small Computer Interface storage system that can accelerate the login request (Login) of the iSCSI storage system. Background technique [0002] Hard disk technology is changing with each passing day, and the hard disk space has been increased from Mega Byte (MB) to Giga Byte (GB). With the advancement of network technology, a communication protocol standard named Internet Small Computer Systems Interface (iSCSI) was proposed by IETF (Internet Engineering Task Force) to use TCP / IP (Transmission Control Protocol / Internet Protocol) The communication protocol connects multiple computer hosts in series to form a virtual network storage server, which has high-speed transmission capabilities and unlimited expansion / backup capabilities to expand the capacity of virtual storage devices. The storage server implemented through the iSCSI com...
