Embodiment 1

[0042] Embodiment 1 of the present invention provides a disk array-based FC network data monitoring system, such as figure 1 As shown, the FC monitoring system is connected to the FC network through an optical fiber, and collects data in the FC network.

[0043] Such as figure 2 As shown, the FC monitoring system includes a FC monitoring card, a processor and a disk array;

[0044] Wherein the FC monitoring card is connected to the FC network through an optical fiber, and connected to the processor through a PCIE interface, and the processor is connected to a disk array through a SATA interface.

[0045] The FC monitoring card is used to receive optical signals and perform photoelectric conversion to submit FC frame data to the processor through the PCIE interface;

[0046] The processor is used to package the FC frame data received from the FC monitoring card, and each time the processor writes the data to the disk is an IO operation. In order to avoid frequent IO operatio...

Embodiment 2

[0048] Embodiment 2 of the present invention provides a kind of FC network data storage method based on disk array based on the data monitoring system of above-mentioned embodiment 1, and specific steps are as follows:

[0049] Such as image 3 As shown, the method includes applying for message cache and cache queue, creating FC message receiving task and storage task, system initialization and FC message processing.

[0050] When the processor is processing data, it first applies for M message buffers, and the message buffers are of a fixed size, which is the same as the set data block size for packing the FC frame, i.e. 8Mbytes;

[0051] At the same time, apply for two cache queues, respectively cache queue A to be used and cache queue B to be written. The cache queue A is used to receive cached FC data blocks and pack them according to the set data block size. Queue B receives packaged FC data and writes the data into the disk array.

[0052] The processor creates an FC m...

Abstract

The invention provides a disk array-based FC network data monitoring system and storage method, characterized in that the system includes an FC monitoring card, a processor and a disk array, and the FC monitoring card obtains FC messages from the FC network through optical fibers, and passes The processor packs the FC frame data, and executes the receiving, buffering and writing of the FC data by creating multi-tasks and using multi-threads. The system of the present invention doubles the storage efficiency of the system based on the disk array for data storage. By adopting the direct writing method based on logical sectors and the writing method based on large data blocks, the overhead caused by the use of the file system is avoided, and the storage efficiency of the hard disk is improved. Write rate, while avoiding excessive calls to system IO to increase system overhead, using multi-tasking to further increase the write rate of the hard disk, solving the ultra-high bandwidth FC network storage requirements and inefficient hard disk storage rate the contradiction between.

Description

technical field [0001] The invention relates to the technical field of high-speed data storage, in particular to a disk array-based FC network data monitoring system and storage method. Background technique [0002] Airborne Fiber Channel (FC) network research and development, testing and maintenance are inseparable from data monitoring, monitoring is an important means of FC network research and operation. Data storage is the basic function of the monitoring system, and it is very important to ensure the high speed and security of the data. [0003] In order to reduce equipment costs, many monitoring systems are based on PCs. The working principle of the PC-based monitoring system is as follows. The FC network data is collected through the FC monitoring card, and then stored in the local disk. However, the commonly used FC network link rate is as high as 2.125Gbps, while the maximum storage rate of a common single disk is only 190Mbytes / s, and the effective rate in actual...
