Unless you have your own dedicated server, you are prone to limits put up by hosting companies. This applies to every hosting company including gigarank and godaddy.
Inode is one such limit. Every shared or VPS hosting has a inode limit - for example say 50,000. Its likely that VPS has higher inode limits.
A file or folder is considered an inode. So if you are having 500 files and 50 folders, your inode is 550.
A common wordpress installation has more than 1500 inodes. Thats just the files and folders used by wordpress - if you have your own uploaded images and files, this will go higher. I am not sure what you host - but keep this in mind.
Also if you use mail, I think every mail received or sent stored in the hosting account is treated as an inode.
So if you exceed your inode limit, you will be asked to upgrade.
But you might hit other limits sooner than inode limit like CPU/RAM limits. Every site uses CPU. There are CPU limits are exerted by the hosting companies and you might soon exceed these limits..

There is no such thing as unlimited hosting - you need to find exactly the limits imposed by any hosting. I think gigarank administrators can clearly tell whats the advantage of hosting with them rather than with godaddy.
