Re: Zero data loss solution

"Zero data loss"

This is a requirement without bounds which means that there is no correct answer.
What if someone cuts the cable?
Or there is a power failure?
Maybe a circuit quits working in an I/O card?

Is the transmission distance less than 1 foot? 1000 feet? 500 miles?
What are the two SANs involved? Do they have replication firmware installed?
What is the replication time frame? 1 second? 1 hour? 1 week?

As you can see, there are just too many questions that are not answered in the specification.
