The thing that's bad about these things is you know they are putting in a system that if it works is not optimized nor sized correctly at best. At worst it's unstable and unusable. Either situation likely gives the product somewhat of a poor reputation. What I wish companies would do is seek out people who actually have the experience to do it right and/or train their people.
I've been playing around with Server 2012 with Essbase this weekend by the way. It didn't like the Weblogic deploy and I didn't have the patience to dig under the covers. It's pretty happy with just Essbase. Also looks like even if you use more threads than processors Essbase limits it; which in my case with my 4 disk raid SSD may mean hyperthreading would actually give me a lift for big aggs. Very curious to check that out the next reboot here.
