Problems solved by technology

[0007] At present, there is no unified and perfect method to systematically test the various performance indicators of the above-mentioned storage bodies. When selecting storage devices for the broadcast system, various technical indicators of various storage devices to be selected are often based on different design requirements. They are tested separately, which not only prolongs the test cycle, but also cannot guarantee the integrity and reliability of the test. Therefore, the TV station urgently needs a comprehensive and complete test method to help the TV station choose a suitable storage system in the design and construction of the broadcast system. body and how it is structured

Embodiment

[0033] This embodiment is a method for selecting and testing broadcast storage devices. The test system used in the method is as follows: figure 1 As shown, it includes: multiple test workstations, file system servers and test management workstations are connected to storage access ports on the storage body to be tested through switches to form a test network. Such as figure 1 As shown, there is a test management workstation, in which a virtual file generation module, a read process management module and a write process management module are deployed. There are also multiple test workstations (due to the limitation of drawing, figure 1 Only 4 are drawn in the figure, but there can actually be many), in which the read process simulation module and write process simulation module are deployed. In addition, the tested memory bank is also connected to the network through its own multiple storage access ports (due to the limitation of drawing, figure 1 Only 6 are drawn in the fi...

Abstract

The invention relates to a playing and memorizing device type selection testing method. A system using the method comprises a plurality of testing work stations, a file system server and a testing management work station which are connected to a tested memory bank through switches to form a testing network and a testing device. The playing and memorizing device type selection testing method comprises the steps of generating simulation files, testing bandwidth of the tested memory bank in a normal work state, testing fault tolerance of the tested memory bank, testing the performance of the tested memory bank and finishing testing. The method tests the bandwidth, fault-tolerant capability, operating performance and other situations of the tested memory bank by simulating various business requirements and emergency situations encountered by the tested memory bank in the playing system and can provide an important reference basis for type selection of the memory bank in the playing system.

Description

technical field [0001] The invention relates to a type selection and testing method of a broadcast storage device, which is a method for selecting a suitable storage body in the construction of a broadcasting system of a TV station. Background technique [0002] In the current digital broadcasting system of TV stations, a large-capacity storage body is often required to store the program materials to be broadcast. The storage used in the broadcasting system of the TV station is different from the traditional storage in the application method, which is mainly reflected in the following aspects: [0003] Considering the safety factor, the storage banks in the broadcast system are generally configured as active and standby. Under normal circumstances, the active and standby storage banks are used in turn to share capacity and bandwidth. However, in emergency situations, if When a memory bank fails, the other memory bank needs to bear all the bandwidth pressure, so the requirem...
