Given the fact that the ESS storage server, which is commonly used in zSeries environments, offers seamless peer-to-peer remote copy functions for disk volumes, even your entire data center can burn down but you can still resume the guest in the backup data center. Once swsuspend stabelizes in the kernel, we should look at what needs to be done in order to make it handy for guest migration on the mainframe...
