WampServer

Ok, so I'm using wamp5 on my intranet website and its working great. While poking around in PHPMyAdmin however, I found this variable named Innodb_buffer_pool_pages_free and it says it keeps track of how many free pages there are in the database. Does that mean that is how much more room I have to store things or is it something else? I was just wondering because eventually I will need a lot more free space then 84 pages. Thanks
