Per Server CAL
With the Per Server CAL model, a separate CAL is required for each unique device that accesses a server simultaneously. During setup, the server administrator enters the quantity of CALs purchased for the specific server. If this quantity were set to 30, only 30 computers would be allowed to connect to that server simultaneously. However, if that server served a pool of 100 computers, all the computers would have server access as long as no more than 30 were connected at the same time. After a computer disconnected from the server, a CAL would be freed so that another computer could connect to the server. If multiple servers are used to load balance, separate CALs are required for each server. For example, if you were using two exchange servers and purchased 200 Per Server CALs, you would likely assign 100 CALs to each server.
Ez nem az? (volt amíg nem öltétek le :))
