I'm looking for a good solution to add NAS to a client's network. The amount of data to be stored is only aout 50 Gigs, and is not likely to grow beyond 80 Gigs. The network is managed by active dirctory, so I need a solution that is active directory compliant. RAID Mirroring is required, and integrated tape backup is desired. Also (least important) HDD scalability is an issue - though it likely won't ever need more than 80 Gig, it might be necessary at some point to upgrade to 120 Gig. Any suggestions on hardware that will fill this need for me are greatly appreciated. I will also post my findings as well, maybe they'll help someone else in the same boat.
