I have a singe dell 1855 blade enclosure with 6 servers. I want to migrate my main SQL 2000 database server from a traditional 4u server with an internal raid 5 array to a blade. In my blade enclosure I have dual Brocade SW3014 2gb fiber channel switches and all of my servers have QLogic 2342 daughter cards supporting dual fiber connections. What I want to do is add dual msa1500cs enclosures with five 15k ultra 320 drives in each msa30. I was thinking about putting both set of five drives in a raid 0 and mirroring the 2 enclosures. This way I wouldn’t have a single point of failure. I have will have 2 servers (one offline and set to WOL in the event server 1 is non responsive), each server has a dual FC card hooked up to different switches and different msa1500cs enclosures. Now this all sounds pretty spiffy in my head but this is my first SAN and I think I need a reality check on two things.

1. Can I have the QLogic 2342 card mirror 2 different VLUNS on separate channels via hardware?

2. Is putting my five discs in a raid 0 worth the performance increase to failure potential over a raid 5 array on each SAN

I hope all this made
