How do you plan to house, connect, power and monitor them? I calculated we would need 3 racks for the arrays, servers and switches. We have the space in our datacenter so that won't be an issue. > so you want a redundant storage system?

The application would probably write to both clusters at the same time. The application has two sites also and I would locate this storage close to it. > This sound all very ambitious to me.

We have been looking at a Dell PowerValut group of arrays or the Compellent (BSD isn't so bad). I'll take a closer look at the IBM too. But since this data will exist no where else, I would like some additional redundancy above the security the array and DR site provide. So far, complete solutions to handle all of this go well above my budget. Thank you! -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
