More importantly, it's very hard to determine if it does work. You have to fail it over to tell, and do it enough times to be sure that it'll really work when you do need it. That is, it might work five times you test it, and then when the real event occurs, the database is corrupt. In addition, it's hard to test because putting together a test infrastructure is itself very costly.

The product being considered is Mirror View to go with an EMC SAN/ Chris, the reason DoubleTake is not an option is based on the understanding that the replication is a "best effort" process and is not guaranteed. According to EMC, Mirror View is confirmed replication between sites. The bottom line, though, is that if this doesn't work, then it's not worth the huge chunk of money they are asking for it.
