The OpenDev Collaboratory (in which OpenStack itself is developed) relies heavily on AFS and has for around a decade run OpenAFS clients and servers on OpenStack Nova instances. Sadly I don't have an answer for your dilemma, but am similarly interested. In our case, our OpenAFS servers all have interfaces on directly-connected provider networks. The only cases where we do AFS through floating IP are OpenAFS clients. While I haven't observed performance degradation related specifically to this, because we distribute our servers and clients globally the latency is fairly debilitating to throughput already. We've also been evaluating kAFS off and on for our AFS clients, but doubt it deals with these specific protocol challenges any better than OpenAFS. I've heard AuriStor (a commercial fork) has implemented some extensions to/revision of the protocol in order to make it more efficient over the modern Internet, so might be worth looking into if being strictly open source isn't a requirement in your environment (in OpenDev we only use open source software, so don't have direct experience with it). -- Jeremy Stanley
