Looking at ways to implement a HA solution on Server 2008.
I had a look at DFS Replication but the problem is that it only allows a single namespace server and selecting sharing folders with multiple target locations.
Failure of the namespace server would result in not being able to access folders using the namespace. Additionally from what I've read, there is no mechanism to lock files when opened by one user, so there'll be issues of incorrectly opening/saving data here.
Alternatively, I can setup a failover cluster as the following guide:
However, this arrangement does require shared clustered storage and I'm no looking to invest on any expensive SAN solution. I thinking possibly using some other means of storage virtualisation.
Basically, I like to setup a HA file server with just two servers and in the cost effective way. If there any suggestions on achieving the mentioned, please let me know. Thank you.
