Hi all,
We're going to be migrating a bunch of small servers (30 - 40) of random instances and such to a couple larger more robust servers.

I am curious to know of some good stats I can query to get an idea of how much the database is used, how heavy the usage is, etc... so I know how to plan for the server hardware and how many databases I can put on each server versus the amount of CPU/RAM we have available.

Basically, there are some cases where we have SQL databases that are lightly used by some applications and could easily be put together on the same server, but others in which they probably benefit from a dedicated environment (IE..heavy usage, etc)

So... any stats that would be beneficial for me to look at that people are aware of? Maybe a point in a good direction to read/look

Thanks,
Tim

It is purely based on your environment. This include the hardware and other resources. I suggest to create some benchmark data like what is the resource utilization, user connections etc. which help you to consolidate the servers/databases.

+1 to bench-marking, hard to tell what is what without knowing your basic daily load. I would recommend using PerMon or a similar tool to perhaps tally up some stats for a week. You could also look at some DMV to determine the number of reads your servers had logged since the last service restart and compare them to a "known" busy server (to get an idea).
