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?
This is a good question. I had heard that GFS had been tested at
somewhere near 300 nodes or something, but further investigation
has shown that those tests were using the old GULM.
As I understand it now, with DLM, the system is limited a practical
limit of around 16 nodes. Is this still correct?
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.
Another very good question, indeed.
