I'm in the process of putting together 3 CineWave systems all sharing 1 storage array. Rorke had a decent solution for me, but it looks like the vendor I'm going with is an outfit from San Francisco called Grande Vitesse Systems (http://www.gvsnet.com/).
However, having said that... I haven't actually USED their stuff yet so I can't vouch for the quality or reliabilty myself, but the people are knowledgable and everyone I can find who has their stuff says very complimentary things about their products.
As an FYI - the cost for the drive system (including the 2Gb Fibre Channel HBA for the chassis and a Fibre Channel Raid Controler... which I think is expensive) is about $24,000 for 1TB of usable storage (the drives are mirrored, so it is actually 2TB of raw storage) which should give you in the neighborhood of 10-15 hours of Uncompressed Cinewave SD Goodness™ (depending on the format you choose, of course).
