Problems solved by technology

Therefore, based on the existing network environment, the rate at which data is imported into the iSCSI target (target) in the iSCSI system is low, which in turn leads to low performance of the iSCSI storage network.

Embodiment 1

[0022] Below to figure 1 As an example, the method for importing data into an iSCSI target provided by Embodiment 1 of the present invention is described in detail. figure 1 The flow chart of the method for importing data into an iSCSI target provided by Embodiment 1 of the present invention. In the embodiment of the present invention, the subject of implementation of the following steps may be an iSCSI initiator (initiator), but it is not limited thereto. The following Take the iSCSI initiator as the implementation subject to describe in detail. Such as figure 1 As shown, this embodiment specifically includes the following steps:

[0023] Step 101: Receive at least one data write request within a preset time, each of the at least one data write request carries target data and a disk location where the target data is to be written.

[0024] Before receiving the data write request, the iSCSI system first performs initialization login. In the initialization login phase, the i...

Embodiment 2

[0040] Embodiment 2 of the present invention also provides an iSCSI initiator for importing data into an iSCSI target, so as to implement the method for importing data into an iSCSI target in the foregoing embodiments of the present invention, such as image 3 As shown, the iSCSI initiator is applied to the iSCSI system including the iSCSI initiator and the iSCSI target, and mainly includes the following functional units:

[0041] The receiving unit 301 is configured to receive at least one data write request within a preset time, where each data write request in the at least one data write request carries target data and a disk to which the target data is to be written Location.

[0042] After the initialization of the iSCSI system is completed, the time window timer is started, and the data write request is started to be received, and the timer ends when the timer reaches the preset time length. Within this preset time, the iSCSI initiator can receive at least one data writ...

Abstract

The invention relates to a method for importing data into an iSCSI (Internet Small Computer System Interface) target and an iSCSI starter. The method comprises the steps of receiving at least one data write-in request within preset time, writing data with adjacent disk positions carried in the at least one data write-in request into the request for combining to form a combined data write-in request, dividing the combined data write-in request according to maximum message segment length of a TCP (Transmission Control Protocol) link and a useable buffer area of the iSCSI target, continuously transmitting a plurality of data write-in requests after division to the iSCSI target, and allowing the iSCSI target to write data carried in the data write-in requests after the division into the designated disk positions. The method realizes the combining and the division of the collected data write-in requests, and the proportion of SCSI (Small Computer System Interface) data transmission in the TCP link is increased.

Description

technical field [0001] The invention relates to the technical field of network storage, in particular to a method for importing data into an iSCSI target device and an iSCSI initiator. Background technique [0002] With the rapid development of computer technology, information data is increasing geometrically, and the storage of information data has become an urgent problem to be solved. In order to solve this problem, the application of network storage technology was born. Internet Small Computer System Interface (iSCSI) is a technical standard based on the IP protocol, which allows users to build a storage area network (Storage Area Network, SAN) through a TCP / IP network. With the emergence of iSCSI technology, users who use LAN as the network environment can easily and quickly interactively transmit and manage information and data with only a small amount of investment, so building an iSCSI system with large capacity and high throughput , which is of great significance t...
