[OpenAFS] Any feedback on an AFS fileserver serving very large volumes?

[Renata Maria Dart]

Based on some encouraging rumours, we are thinking about trying out 
an AFS fileserver to serve very large volumes, 100gb+.  Does anyone 
who has tried this, or thought about it, have any feedback regarding:

1.  (solaris) hardware best suited for this, both cpu and storage
2.  size of partitions
3.  options on the fileserver and volserver processes
4.  client considerations such as cache size and afsd options
5.  the largest volume you've tried and any stories about 
    moving or backing it up
6.  performance of the server
7.  anything else of interest

Thanks in advance,

Renata
