[rrd-users] Just a basic question... one or multiple RRDs?

I am going to be using RRD to store metrics on server health. For each 
5 minute interval, the following type of data is collected:
     CPU Utilization (%)
     Server Load
     Number of Processes
     Number of Threads
     Used Memory
     Free Memory
     Memory Cache Hit Rate (%)
     Filesystem A Space Used
     Filesystem A Space Free
     Filesystem B Space Used
     Filesystem B Space Free

Can I create just a *single* RRD file to store all this different type 
of data? Or is it wiser to create separate RRDs... one for each 
group/type of data? My first instinct was to go the multiple RRDs 
route. But after thinking about it longer, I don't think I need to for 
any greate reason and it would be easier to just make one.

Thought I would run it by some people that experience ... this is my 
first time working with RRD.
