which type of raid and setting up a raid on Solaris
 

I have 2 hard drives that are close to but not exactly the same size. I'd like to run them in a raid. I am a beginner at raids. I tried search for the raid documentation for solaris specifically but failed to find it. Where is it? I found a bunch of other junk instead. Could anyone tell me what the best type of raid is? I want to see both hard drives as one and have them setup so that if one fails, the other one takes over, and I lose no data. Sorry for my newbie question. My hard drives are IDE. I am not using a serial ata raid controller. Thanks.

docs.sun.com is usually a good start:

How can you judge it's junk if you are a beginner with RAID ?
Depends on the needs you have.
Then what you want is RAID-1, better known as disk mirroring.
IDE is okay.
So what you want is software RAID.
If you are using Solaris 10 or newer, I would suggest to use ZFS raid capabilities, they are far easier to manage than other technologies.
Just create two partitions of the same size on each disk, and have them mirrored, that's it. Beware that the root partition can't be used yet with ZFS though.

If you want full redundancy, you can mix ZFS and SDS like this guy does:
