Hi Wendy, thanks for the response again. Sorry, again just to clarify, I meant to say that MY configuration will consist of the app cluster nodes accessing an iSCSI SAN using GigE NICs. I don't have any PCI slots on these machines available to use HBAs on them or believe me, I would be using iSCSI HBAs. Didn't mean to say that that's a limitation of GFS or anything, sorry :) Yes, I guess the only sure way to find out is testing but unfortunately we're a start-up company with no resources (esp. human) and limited equipment or methods to test the workload other than putting it out into a field test scenario and measure/watch it during beta/field testing. Lab testing won't be possible at all. Which is why if I could, I'd like to make a decision now based on other people's experience and just stick with that solution without having to re-do everything with the other solution. If you know what I mean. I just hope there are more people reading this who have real-world implementations who could help me with some advice :) Best Regards, \R -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
