One of the nice things is you can tell it to mirror the original drive so you don't have to reinstall. Other cards (like the 3Ware Escalades) kill both drives data when you create the mirror, so you have to reinstall/restore backup.

Its very recommended to have only one disk per IDE/ATA channel since it can only deal with one request to one device at the time. > Drives are both Seagate 7200rpm 40Gb ATA100 and the controller supports > ATA100 also.

I have a very similar setup with a vinum raid, using 4 drives on 2 Promise ATA100 (the cheapest one) controllers. They work flawless. Just check the hardware notes on freebsd.org. There are several IDE/ATA controllers that are supported under 4.8-STABLE. > Solutions must be cheap i.e under 50 UKP as the wife will kill me for > spending any more ;-) > > Cheers all cheers, tom ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
RE: ATA mirroring solution required
Well, if you're willing to spend some money, getting a hardware RAID1 2-channel IDE controller would be the way to go. As a cheaper alternative, I, personally, would change the drive configuration so that each channel had a HDD master and a CDROM slave. Hope this helps, Tyler McGeorge ...to the rescue... -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Chris Smith Sent: Tuesday, October 21, 2003 2:48 PM To: [EMAIL PROTECTED] Subject: ATA mirroring solution required Hi, Got a bit of a sticky situation. I have a bog standard Compaq AP230 workstation with two IDE channels and 3 devices so far (two CDROM devices and a hard disk). I want to add a second disk as a software RAID1 mirror of the primary disk. I know how to do this in FreeBSD so thats not a problem - the hardware side is. The only available IDE port I have would be shared with the existing hard disk i.e two hard disks in RAID1 on the primary IDE chain. AFAIK this is bad for performance reasons. Drives are both Seagate 7200rpm 40Gb ATA100 and the controller supports ATA100 also. Running 4.8-STABLE. Where do I go? I was looking for a secondary controller to give each drive it's own channel on the controller (ie a promise/HPT one) but have no experience with these under FreeBSD. Can someone recommend one if possible that works flawlessly or an alternative solution? Solutions must be cheap i.e under 50 UKP as the wife will kill me for spending any more ;-) Cheers all -- Chris Smith http://www.infinitemonkeys.org.uk/ ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]" ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
