There are some other issues to conside. If the Web server is to be used to provide access for large file downloads, it may be sensible to consider placing those files on higher performing disk devices under the NAS appliance. This applies equally for areas to be used for FTP upload and download (assuming that is a permitted operation).
Using NAS as the storage for Web servers can also provide some additional benefits. Most NAS products provide snapshot or cloning tools. This can be used to replicate web server data for testing, update distribution or to create additional servers for load balancing. Finally, NAS provided storage can be accessed by multiple web servers concurrently, allowing simple web server clusters to be implemented.
