Another plus to software raid is data portability. Consider that down the road you might be moving from Intel Pentium to Itanium. Your hardware RAID controller may not work or be supported on your new platform. Now what? The data on the drives is stored in a proprietary format which probably cannot be read unless you have a functioning controller. Your only path would be to have the data tranfered via a dump/restore or some alternative method (network?). If you use the native Linux software RAID, chances are very high that you can simply unplug the drives from one system and move them to the other. Of course, I'm not including the OS partitions and kernel binaries in this example as that is a whole different compatability problem. Performance is one consideration when comparing software versus hardware. However consider that on i86, Linux software RAID is implemented in the MMX processor (as best I know), so impact is minimal. -christoph ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
