The controller in an Ultra 1 is only good for 10MB/sec max. Yes, it looks like you're bottlenecking there. Additionally, as free as they were, I would not recommend using those drives in that chassis; the Ultra 1 doesn't have sufficient cooling for those drives and they will fry themselves in short order. 15,000 RPM drives run very hot and normally require much more airflow than 10,000 RPM drives. _______________________________________________ Aurora-sparc-user mailing list [email protected] http://lists.auroralinux.org/mailman/listinfo/aurora-sparc-user Aurora FAQ: http://www.ecs.soton.ac.uk/~mas01r/aurorafaq.html
