This is a great way to build UNIX based NAS server with all goodness of ZFS.
Sun recently announced the addition of powerful developer tools and expanded professional service capabilities to help developers better leverage the growing open source communities that are fast changing the economics of the storage IT landscape. Over 3,000 members and 30+ projects within an active and growing OpenSolaris storage community demonstrate a groundswell within the storage industry for developers and enterprise companies to use open source alternatives to expensive proprietary storage offerings.
Sun further claimed that average developer will be able to set up an OpenSolaris server is about 10 minutes. You can build a OpenSolaris operating system storage server in 10 minutes or less.
