Analysis Server architecture

We have a large cube (over 500GB) and several other relatively small cubes built using AS 2000. We are now in the process of upgrading the environment. Basically we are going to buy new infrastructure and use AS 2005. And the OS is XP. The large cube is the one that is widely used in the company by at least over 200 people. Small cube has very few users. My question is what is the best architecture we can use 1. Whether to use one large machine and then have one instance of AS. All cubes are to be migrated to this instance. Issue with this option, we can not makesure we give more resources to the important cube. 2. Have multiple instances of the AS running on the server. Use MS Resource manager (new product shipped with XP server) to manage the resources. Has anyone used MS resource manager or aware of any issue with it ? 3. Use clustered environment – I do not know how use this to allocate more resources to the important cube. Any thoughts ? Much appreciate, any pointers on what we are trying to achieve here . Thank you
