Raid 1 for spanned hard drives possible?
|
From: J on 2 Apr 2010 14:14 I inherited a client that has the following setup : SBS 2003 standard sp2 Dell CERC ATA Raid Controller It has 2 drives : 1 is a simple 80GB drive partitioned into C and D; the other drive is 150GB dynamic spanned to the D. Can I put in another 250GB drive and mirror it to the existing partitions? TIA
From: Cliff Galiher - MVP on 2 Apr 2010 14:20 I doubt it, but even if you could, I'd strongly discourage it. IDE drives were never designed for server use because ATA as a protocol is not robust. SCSI has a long heritage of being very intelligent, so it (or SAS) lends itself very well to RAID. The setup you describe, with a span that you'd then be trying to mirror, would probably crush your performance on simple IDE drives. -Cliff "J" <japhyrider2005(a)yahoo.com> wrote in message news:0139b7ab-b7ac-4a18-8863-4cec9b97c82e(a)h27g2000yqm.googlegroups.com... > I inherited a client that has the following setup : > SBS 2003 standard sp2 > Dell CERC ATA Raid Controller > > It has 2 drives : 1 is a simple 80GB drive partitioned into C and D; > the other drive is 150GB dynamic spanned to the D. > > Can I put in another 250GB drive and mirror it to the existing > partitions? > TIA

I can't directly answer your question, but, I'm going to bet that you can't just mirror the existing drive (physical) without trashing it. BTW, you said they are SCSI in your other reply, but you state ATA in the controller above. So, is the 150 an ATA or SCSI? -- You can't trust your best friends, your five senses, only the little voice inside you that most civilians don't even hear -- Listen to that.

I'm guessing from the description that you did this with software RAID (ie, the RAID built into SBS). In which case, the answer is a simple no. -- Charlie. http://msmvps.com/blogs/russel "J" <japhyrider2005(a)yahoo.com> wrote in message news:b1c9eb60-de93-4004-8e7a-bce4d9a394a2(a)r18g2000yqd.googlegroups.com...
