Thanks for your reply!
But now I'm confused ....

Yesterday the presales support told me that there is NO possibility to get multipathing working in combination with Citrix Xen. I've seen some posts regarding this issue on this forum, but all topics are a little bit outdated. So, whats right now?

Scenario:
I've got one big open-e Server that should serve 8 of my Citrix Xenserver. I'm thinking about multipathing because of the better performance in the comaprison to a balance rr bond.

best regards
Sebastian
