I'm quite imporesses that Nexenta can build storage metro cluster (site to site storage mirroring). As Nexenta is built on Illumos (successor of OpenSolaris) I was thinking what kind of components are involved in their storage metro cluster. Could anybody enlight me what components are doing this site-site mirroring and if these components are open source so one can build similar storage metro cluster on his own? ZFS is local filesystem so what takes care of clustering?
