[Linux-cluster] Performance questions

[Shailesh]

Hi,
    I have two performance related queries for GFS,

1. What would be the optimal number of GFS nodes I can 
   have on Gigabit ethernet lan, is it unlimited?

2. How would the comparisions between GFS and Lustre file system 
   look like in terms of 
   - Number of nodes supported for optimal performance and
   - Bandwidth usage.
   ?


Thanks & Regards
Shailesh
