no - I don't know SQL server ..

the question was out of curiosity - well I checked tahiti (otherwise I wouldn't dare to ask a question here), but I didn't find a real answer. No concepts that describe such a combination, but also no rule that a cluster cannot be partitioned.

Maybe crosschecking the concepts, admin and performance tuning guide was not enough.

Would a partitioned cluster table make any sense? Could it (if technically possible) accelerate data access? The more I think about it, the more I tend to say no.

But I dont want to waste your time ...

thanks anyway!
