Currently, we are hosted on shared ZCS server. Since our needs are growing, I was planning to move to a dedicated ZCS server for capacity and performance. The hosting company recommends to move to a cluster (I assume, the same platform as it runs now) with dedicated mail store instead. I am trying to understand difference between both setups:

- administration
- resilience
- growth
- performance

They offer to provision a full blown server just for the mail store, which I consider overkill. Why not to run ZCS on it as well?

Thanks
