[gpfsug-discuss] NDS in Two Site scenario

[Marc A Kaplan]

Careful! You need to plan and test, test and plan both failure scenarios 
and performance under high network loads.
I don't believe GPFS was designed with the idea of splitting clusters over 
multiple sites. 
If your inter-site network runs fast enough, and you can administer it 
well enough -- perhaps it will work well enough...

Hint: Think about the what the words "cluster" and "site" mean.

GPFS does have the AFM feature, which was designed for multi-site 
deployments.
