none of these will work. you need to use proprietary solutions that will intercept Write calls to the OS, transfer them to DR site, actually write to remote disk, get an acknowledge from there, write to local disk, and *only then* acknowledge a successful write to applcation.(now u know why zero data loss solutions cost a bomb and screw up app response times)
