This is a long term archive and this data will only
reside here.

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.

The
application would probably write to both clusters at the same time.Â
The application has two sites also and I would locate this storage close
to it.

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!
