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. -------------- next part -------------- An HTML attachment was scrubbed...
