You can try self-powered sata expander boxes. Basically a sata jbod enclosure with smps. Don't know about the cost though. > 2.

Currently only decent way to tie together storage on different machines is via iscsi. Comstar has made this much more robust. If you are thinking of HA than expanding the storage you could try open solaris cluster to tie together pools using iscsi in an HA config. I would advice against making everything you have into a single pool. cheers Binu > Idea: > 1.
