A quite informative (but technical) article regarding RaidZ performance is this 2008 blog post: https://blogs.oracle.com/roch/entry/when_to_and_not_to Regarding zpool vs. zfs, I'd suggest any ZFS administration handbook you like. A classic one is the "Solaris ZFS Administration Guide", available online from Oracle at http://docs.oracle.com/cd/E19253-01/819-5461/ I'd suggest chapter 3, then article http://docs.oracle.com/cd/E19253-01/819-5461/gaypk/index.html, then chapter 2 and finally chapter 1, in that particular order. Unfortunately, it is only a HTML version. It used to be available in PDF in the past, but apparently Oracle stopped that practice. Google is your friend anyway. There are also some quite good talks on ZFS basics on youTube and some nice slide sets out there, but I don't have any administration related ones at hand. I have more the technical stuff aimed at ZFS development ready.
