[gpfsug-discuss] NDS in Two Site scenario

[Mark.Bush at siriuscom.com]

Marc, what you are saying is anything outside a particular data center shouldn’t be part of a cluster?  I’m not sure marketing is in line with this then.

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.
