I recently moved into a company that is using NAV 2009 R2. It’s my first time working with this platform and I’m exploring some expansion/high availability options.
Our current architecture is that all of our users connect via a RemoteApp to an RDS Gateway server, which hosts the actual NAV application. The NAV application on that server then talks to a database server that interfaces with an enterprise grade NAS which contains the NAV db and logs. This seems to work well, and I have no issues with the functionality or performance.
My concern is that there are two potentially significant single points of failure - the RDS server and the DB server. We have ~20 users that work in NAV all day every day, as a company we are expanding, and downtime would severely impact our operations. I’ve tried searching around this forum and Microsoft’s website and I’ve found a few things, but I’m looking for some personal views/experiences -
- What does your company do for high availability/redundancy of your NAV system?
- I’ve seen several mentions that NAV 2009 can’t be clustered - how do you load balance, multiple gateways?
- Do normal SQL2008 HA techniques apply?
- How do customizations to NAV work in a multiple server environment?
We’ve reached out to our implementation partner about this as well, but we’re trying to expand our knowledge base. Thanks for any information you can provide.
