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.<br />
<br />
1. Can I have the QLogic 2342 card mirror 2 different VLUNS on separate channels via hardware?<br />
<br />
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<br />
<br />
I hope all this made <br />

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
