[dba-SQLServer] sql server 2005 database mirroring

The article does not explicitly say that whether there is a bug problem or 
not with db mirroring, just lack of it in production use.  I hope that it 
gains popularity fast so that they can release db mirroring ahead of 
schedule they just set forth.  It is a pretty cost-effective way for 
disaster recovery compared to clustering.
