BOBJ - Hardware Requirement

Hi,

We are currently having BW/BI NW 7.0 EHP1 and also ECC 6.0 EHP4. We are researching about the purchase of BOBJ enterprise. What is the general recommendations in terms of hardware requirement we should be aware of and based on the users who are already using the tools of BOBJ (like accelerator, dashboards, crystal reports etc) how much CPU/memory is it utilizing say for a Concurrent users: 1,020 which are light to moderate users.

Thanks,

Murali.
