This is very true. Without external storage or SAN, the second I/O-Service domain can not be truely independent. One would also have to ensure that networking and storage connectivity is replicated in the second I/O-Service domain. This requires a good understanding of the hardware architecture to plan out. Ultimately, with features like Live Migration... this may be a moot point unless you only have a single server. Or you have a specific need to have an I/O domain.

Unless people are booting from SAN or are using external boot disks to compliment the internals, I can currently see what advantage having multiple i/o domains in a single box gives - anyone ? -- This message posted from opensolaris.org _______________________________________________ ldoms-discuss mailing list ldoms-discuss at opensolaris.org http://mail.opensolaris.org/mailman/listinfo/ldoms-discuss
