Hi Tao,

Glad to hear things are working for you.  Rather than ask a very open
ended question about how Drupal scales - for which the only reasonable
answer is "it depends" - you might try outlining your requirements.  
How many sites, how many users, how are the sites going to be used,
administered etc.  Also some information on your current IT
infrastructure - types of servers, network etc. would be helpful.
