Mirroring technology

A cluster technology. It is the two servers built on the same local area network that mirror the hard disks of the two servers through software or other special network devices. Among them, one server is designated as the master server and the other is the slave server. The client can read and write only the mirrored volumes on the master server. That is, only the master server provides services to users over the network. The corresponding volumes on the slave servers are locked to prevent data access. The master/slave server monitors each other's running status through the heartbeat monitoring circuit. When the master server is down due to a fault, the slave server will take over the application of the master server in a short period of time.

Jinko solar panel, Canadian Solar panel, ja solar panel etc.all of which are among the top 10 world-renowned brands. The original A grade product is mainly mono crystalline and half cut cell solar modules, with a power range of 400watts to a maximum of 700watts.quality warranty is 25 years.

A grade, this type of film is characterized by a neat and uniform appearance, printed electrode grid lines, no broken grid, no surface stains, no leakage, no aluminum package, no hidden cracks, no scratches, no black core, no reverse current, stable electrical performance, and high conversion efficiency
Using solar cell testing equipment to measure and screen, the conversion efficiency, filling factor, and appearance that meet certain standards are first level. Generally, the conversion efficiency, filling factor, and appearance of first level are better than those of level B
The level of solar panels can be divided into first level, second level, third level, and fourth level, and the first level components can be divided into first level+and first level - two levels. The second level is also the same, and the cost difference between different levels of solar panels is also very large.
