Is there a disk mirroring product for Linux? I want to make my server more resilient. Thanks.

Many (maybe even most) RAID cards will work in Linux. You can also use software RAID.

Thanks. What can I use for software mirroring.

Software RAID
 
Unfortunately.. you have to setup software RAID (and some hardware RAID) at the time you create the diskpartitions (to the best of my knowledge).

You can not simply "turn it on" with a running system and have it protect your data.
