Farhan, thanks for the contribution.

No doubt it will nudge many to make the move to mirroring. And for those that have not started to use mirroring, get going. It has little downside, and huge upside.

Based on my non-scientific observation, the passive mirroring process uses around 2-3% of system resources (maybe less). So, if you have multiple production database servers, you can expand their use and set them up as a passive mirror for other production systems. The corollary to this is that a server dedicated solely as a passive database mirror is a waste of resources.
