Thanks Lynn, Greg, & Steve. I think I see the error of may ways now. Let me define this a little more.

It is a single cluster environment (1 active, 1 passive).

It is about 90% OLTP (10% warehouse).

It has 2 instances with 150+ databases.

The total space consumed, excluding backups, is about 500 Gig.

Space is expected to grow at about a 500 Mb/day.

We expect to replace our hardware every 5 years.

Rack mount is definitely prefered.

Not concerned with SLA's at this point.

Backup replication & storage does not need to be considered in this purchase.

The majority of the growth occurs during normal U.S. business hours.

$200k is the very maximum. I would probably scale down from this.
