Rorke has gotten a lot of great reviews on this and other sites.
Personally I've used Medea for the past 6 or 7 years and absolutely love the performance, price and service after the sale. I started out running my CineWave with a 240RT which was actually never approved by Pinnacle for the CineWave because technically the data rates were not fast enough for dual stream uncompressed RT effects. It worked flawlessly until the 3 Way Color Corrector and RT Chroma Key effects came out. That makes the drive chug a bit and slow it down.
So I added the 480RTR and it is totally rock solid. Additionally, striping two RTR's together give me full HDTV editing capability so I'm halfway to HD.
In addition to the Medea I run the Adaptec 39160 SCSI card and use ATTO Express Tools 2.7 for drive management.
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).
Is this vendor setting you up with an approved Fibre setup or are they creating you something that meets the specs of SD throughput and telling you that it will work with CineWave? Just curious. If it's not a Pinnacle approved setup, ensure that you can return it if you have too many problems.
