			<br />A filesystem called <strong><a href="http://www.opensolaris.org/os/community/zfs/whatis/">ZFS</a></strong> was introduced in Solaris 10.
			<br />It goes to great lengths to be fast and reliable. Very reliable.
			<br />Hey kids, try this at home...

			<br />There's a pile of hard drives in my kitchen, living in an old DEC "shelf".
			<br />This array is plugged into an Ultra 5 running build 39 of <a href="http://www.sun.com/software/solaris/solaris-express/get.jsp">Solaris Express</a>.

			<br />ZFS uses the concept of "storage pools" called <strong>zpools</strong>.
			<br />This array forms a zpool called <tt>poolpoolpool</tt> (10 points if you get the name).
			<br /><a href="http://blogs.sun.com/roller/page/bonwick?entry=raid_z">RAID-Z</a> provides redundancy and all 7 disks are happy...

			<br />I've created a filesystem called <tt>media</tt> which is attached at <tt>/export/media</tt>.<br/>There's a video file on that filesystem.</p>

			<br />Thanks to NFS, I'm playing that video on my computer.<br />What happens if I do --

			<br />HAH. 
			<br /><tt>c1t3d0   UNAVAIL</tt> - Gee, I wonder why that could be?
            <br />Now, certain software RAID implementations would've just crapped themselves - they expect disks to disappear with the <strong>power off</strong>.

			<br />ZFS says: <tt>Attach the missing device and online it using 'zpool online'.</tt>
			<br />Screw that, let's finish the episode first.

			<br />One <tt>zpool online</tt> later...
            <br /><strong>This doesn't even show off how well ZFS protects data integrity - I could've written trash to the hard drive while it was plugged in, for that matter.
