If i have 10 server and 100 Client window OS, than how many Device CAL i will require to access this 10 server?Thanks & Regards, Param - MCSE, CCNA ( http://paramgupta.blogspot.com )

Hello, With a Device CAL, you purchase a CAL for every device that accesses your server, regardless of the number of users who use that device to access the server. Device CALs may make more economic and administrative sense if your company has workers who share devices, for example, on different work shifts. You shall purchase 100 CALs since you have 100 Client Windows OS. For detailed information, check this: http://www.microsoft.com/licensing/about-licensing/client-access-license.aspx Thanks ZHANG
