-        article about Sofware RAID and LVM.</p>
-
-        <p>Basic idea behind RAID is to deal with independent disks
-        as an array of drives. Raid 0 uses two or more disks as one,
-        with performance gains without fault-tolerance. From raid 1
-        to 6 they offer diferent fault tolerance mechanisms.</p>

-        <p>LVM or Logic Volume Manager bring one more layer, read
-        <a href="http://www.tuxradar.com/content/lvm-made-easy">Lvm made easy</a>.
-        Partitions under lvm are easy to be resized, moved and there is
-        a tool to help encrypt. There is more freedom to name physical
-        disk names exp; production, development, backups...</p>

-        <p>Until now "from install" there is only one partition,
-        it is good idea to have a system with diferent partitions for each
-        propos. If is a "fresh install";</p>
