It has to be configured in the BIOS and windows needs a raid driver at install to even see the raid drive. But the onboard controller still utilizes system resources. So it is not a "pure" software raid, but a mix of hardware (controller) / software I guess. But I don't really know a whole lot about it. -----Original Message----- From: Mark Kirkwood [mailto:markir@paradise.net.nz] Sent: Sunday, April 30, 2006 7:04 PM To: Gregory Stewart Cc: Theodore Loscalzo Subject: Re: [PERFORM] Performance Issues on Opteron Dual Core Gregory Stewart wrote: > Theodore, > > Thank you for your reply. > I am using the onboard NVidia RAID that is on the Asus A8N-E motherboard, so > it is a software raid. > But as I said, the CPU utilization on that machine is basically 0%.

SATA controller on the A8N-E (as there seem to be a lot of crappy SATA controllers around at the moment). Also (I'm not a Windows guy) by software RAID, do you mean you are using the "firmware RAID1" from the controller or are you using Windows software RAID1 on the two disks directly?
