Prerequisites for successful VOD systems and servers:
1. The network system should be designed so as to avoid network traffic congestion.
2. High-performance switches are tightly integrated with servers, storage systems, backup systems, software, system settings, and client settings.
3. There is a need to continuously monitor and debug the network environment, the use of the network, the throughput of devices and servers on the network.
4. Operate in an environment where there is no dust or air conditioning. Each important server has a UPS protection with remote monitoring. To have ground and lightning protection facilities.
5. Select the appropriate raid. RAID-0 to RAID-7, and double raid. Number of disks, single channel or dual channel.
6. SCSI or FC (Fibre Channel) selection. FC-Fc-al hubs and FC switches.
7. Consider whether to use storage cluster technology, storage area network equipment, and data backup in situations where storage is large, content is preserved, and service requirements are high.
8. The faster the speed of the disk, the faster the search for files and read and write rates.
9. The larger the file system packet fragmentation, the higher the transmission efficiency.
10. Store subsystem to server I/O.
11. The bandwidth of the PCI bus and the device of the PCI device affect whether the data from the storage subsystem can be transmitted smoothly to the system memory.
12. The speed and number of CPUs and the frequency of the system clock can affect the load and bandwidth of the server.
13. The larger the memory and buffer, the wider the bus connection channel. The more digits, the faster the calculation frequency, the better the video service.
14. Operating systems and software can affect service stability, service, and network overhead.
15. Network I/O is an important bottleneck. TCP sessions have very large CPU requirements, limit the number of users connected to the server, and also affect other computing functions that the CPU handles video-on-demand.
16. The ease with which servers and storage systems can be upgraded is a problem.
17. If the application of the server is to provide uninterrupted service, then regular maintenance, rebuilding data, and system upgrades should consider how to continue to maintain services.
18. Server software is installed on the server hardware. This software can support what media format, with what transport protocol, port connection problems will not be fault-tolerant.
19. Client hardware software must also be configured to successfully watch streaming media.
20. In the real world, customer funds are limited, time is pressing, there is no expertise in all areas of talent. And all of the above subsystems have countless manufacturers and products of choice. Each has its own characteristics. The ability to maximize performance is a question mark. The ability of the driver to work perfectly with the operating system and application software can also affect the service.
