This may be true, but redudancy is what's wanted by simply adding to the existing raid group. I understand Sun's approach here, but at least people used to NetApps and the like have gotten used to the ability to add storage incrementally to previous raid groups (its RAID 4, single or dual parity, with automatic raid group separation for performance). To the point of what Linux can do, it now does support the same RAID4 (CentOS5 by the above example) and can grow an existing RAID array.
