[Alug] NAS Application

Hi All Currently run 40 odd servers from the US. All slackware. Just setting up a similar sized operation in the UK. But in the US all servers run from their own HD. I am thinking of building a NAS for the UK Racks and setting the home dirs, mail dirs, conf files etc.. all from a single NAS with a backup server taking snapshots every hour or so. Anyone got any experience with this or any programs (Using apache/mysql/qmail etc..) that have any problems with this type of setup? Ta D
