Abstract
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 negotiation authentication process and generates a packet setting request according to the login request; the kernel module establishes destination environment information according to the packet setting request so 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
The invention relates to the stocking system of a kind of internet small computer interface (iSCSI), particularly a kind of stocking system of internet small computer interface of the request of logining (Login) that can quicken the iSCSI stocking system.
Background technology
Seagate makes rapid progress, hard drive space by Mbytes (Mega Byte, MB) be promoted to kilomegabit (Giga Byte, GB).Along with the network technology progress; Internet small computer system interface (internet Small Computer Systems Interface by name; ISCSI) communication protocol standard is proposed by IETF (Internet Engineering Task Force); In order to form a virtual network storage server through many main frames of TCP/IP (Transmission Control Protocol/Internet Protocol) communications protocol serial connection, it has high speed transmission abilities and the unrestricted expansion/backup capabilities that expands the virtual storage equipment capacity.Storage server through the iSCSI communications protocol realizes can be made up of one or more destination end (Target); Once store data and be called session (Session); Initiation session one end is called originating end (Initiator); Originating end transmits request (Request) package and sets up session with destination end, and destination end receives Request Packet to respond and to set up session online.
Yet under the requirement of transmission speed, the burden of the system processing power that Data Transport Protocol caused also can not be overweight.Because the iSCSI agreement is that framework is on the TCP/IP communications protocol; Then be to join on it with SCSI (Small Computer Systems Interface) interface; If with iSCSI and TCP/IP communications protocol all is to be carried out by host-processor; Storage network at a high speed and great amount of data transmission require can know that host-processor will expend too much disposal ability on transfer of data down bear so must thinking how to reduce the processing of main frame.
Summary of the invention
The technical problem that the present invention solves is, a kind of stocking system of internet small computer interface is provided, in order to quicken the request of logining of internet small computer interface.
The invention discloses a kind of stocking system of internet small computer interface, in order to quicken the login request of iSCSI stocking system to destination end, this stocking system comprises:
One originating end proposes one and logins request in order to set up data transmission channel; And
One destination end is connected in this originating end, and this destination end comes from this request of logining of this originating end and the data transmission channel of foundation and this originating end in order to reception, comprises in this destination end:
One user's morphotype piece is logined request in order to receive this, and this user's morphotype piece is consulted verification process according to this request of logining in order to carry out one alternately, and produces a packet setting request;
One kernel module is connected in this user's morphotype piece, and in order to setting up a destination end environmental information, this destination end environmental information is in order to the supplemental characteristic of this packet setting request of writing down this user's morphotype piece according to this packet setting request for this kernel module; And
One network card is connected in this kernel module, and this network card sends an access request to this originating end according to this destination end environmental information, when this originating end responds a full characteristic phase requests to this destination end, then changes by this network card and handles this full characteristic phase requests.
This request of logining transmits through a transmission control protocol.
Data transmission channel between this originating end and this destination end is Ethernet, fiber optic network or wireless network.
Comprise a TCP offload engine in this network card, be offloaded on this network card, to reduce the load of processor in order to TCP/IP flow with the host-processor of this destination end.
The stocking system of internet small computer interface disclosed by the invention utilizes the network card in the destination end, when the request of logining that each originating end proposed is received through network card and carry out dissection process, to reduce the load capacity of destination end to the request of logining.
About characteristic of the present invention and embodiment, conjunction with figs. is made most preferred embodiment and is specified as follows.
Description of drawings
Fig. 1 is the structural representation according to the stocking system of internet small computer interface of the present invention;
Fig. 2 is the flow chart according to the stocking system of internet small computer interface of the present invention.
Wherein, Reference numeral:
Stocking system 110 originating ends of 100 internet small computer interfaces
120 destination end, 130 user's morphotype pieces
