I'm looking to maintain a home server of media (videos,music,etc.) with some RAID(fallback or redundancy) support that I can update relatively easy over the years.
My high level plan is to buy 1U or 2U racks every year or so that have a lot of harddrive bays, and somehow link these logically (meaning I can treat all the space as one large disk I can connect to).
Is this possible? If so what kind of technologies do I need to use to link the separate computers in such a manner (and as efficient/fast as possible). If not, what other recommendations do you have for building a scaling home server (meaning I can add a few dozen TBs every 2-3 years).
