And not something you really have to be concerned with any more. When we were doing raid arrays on a 386, sure. But unless you are paying BIG bucks for a raid controller, software raid will outperform hardware raid. The fastest raid controller today will never see an upgrade. Within a year or two when the machine gets upgraded, nobody want's to spring for faster controllers. So they remain the same old controllers and everybody hopes they won't crap out because the array may not be recoverable. I'm not talking about the FAKE Raid controllers here. I'm talking about the "qquality" controllers with on-board processors and lots of cache memory. (Which you can never find replacement memory modules for after a few years). Ive ran such contollers jumpered to shutdown the on-board raid processing, and used them just for their multiple independent headers in software raid arrays. -- After all is said and done, more is said than done. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
