Two 3ware 12 port controllers will cost about EUR 1800,- here, I find it quite expensive.. One big advantage of using linux md always was easy monitoring (just check changes on /proc/mdstat and send email alert), and the ease of remote management. Don't know how to do this with hw raid cards. When I have a throughput of say 20Mb/s total on my raid set, that would be fast enough for this system, as it is used by only one client. I think that should not be a problem with cheap sata ports combined with linux md. _______________________________________________ tsl-discuss mailing list [email protected] http://lists.trustix.org/mailman/listinfo/tsl-discuss
