If you want to buy an off-the-shelf NAS then that's different. >I would like to have my mythtv/music/videos on a storage system that >is accessible to my network and can be put in a RAID array.

Or you can have a seperate box with all the drives and nfs mount it to your backend (and all the frontends, and your windows boxes...) You can easily run NFS *and* samba (for windows access) Having 3 tuners and a load of disks in one box has the potential for high CPU and temperatures - and maybe DMA issues. If you are worried about network bw, then drop a cheap gig card in both the NAS and BE. >Is there a more elegant solution to have just the storage somewhere >and hook it up via a network?

For a BE I'd say you're asking for trouble. A glitch here easily causes data corruption. >Does any of this make sense? >Any advice, direction, tutorials, RTFM (with a link to where the FM >is!) would be fantastic. > > Well, the wiki has a fair bit (and you're welcome to add your experiences) My system (which I think is pretty elegant/flexible): * 1.2Tb (XFS,lvm2,raid5) server (6x250Gb SATA + hot spare 250Gb PATA) in tower case. Athlon 1200, 512Mb RAM. * BE: £99 dell server (some intel chip - dunno) 80Gb disk. 2 Tuners * FE1: diskless (boots from NAS) * FE2: 160Gb SATA (for now) I also use the server for video editing.
