Hi All, It may not be directly related to openBSD issues, but I need to ask here since I believe I can make use of openBSD and some services on it to make this project work. Anyways, I am planning for a DR site for our data center. First, we thought if main data center was down, then the DR site should be activated. Then, I got some input from higher level managers like suggesting if it was possible to fail over to DR site for some of the services we are providing. These services include http/https/smtp/pop3/imap. We have a number of different domains for each service.
So, I believe a DNS solution to fail over to a DR site is out of question since we have to maintain not only our own domain, but a number of customer domains. This leads me towards a BGP solution. I read an article from cisco for a BGP solution. They suggest at least 2 extra internal connections between data center and the DR site along with the main Internet connection. Here are my questions: 1) Do you know of any good readings/articles/books for building DR sites? 2) What do you think about the extra connections as suggest in one of cisco's articles when building BGP based fail over to a DR site? Can I just use VPN over the main Internet feeds between data center and DR site? 3) Do you have any example of such a project done with openBSDs? Thanks, Rami
