Hi everyone

(if this is in wrong category pls move it)

I'm about to start a new project :)

but i dont know if its possible the way i think.
i have attached a image to this thread to describe how i would like to do it.

Im about to get 4 MacMini's and would like those to bee loadbalancing for OD, file, and so on to a little branch office.
on those 4 MM's i would like to have like 8 virtual mac osx server running with diffrent roles.

the loadbalancing part comes then (not that i hope so) a MM breaks and then the other 3MM take over the load from the virtual servers. until the forth is replaced.

i hope you get my idea.... :)

Hmm. Not an expert, but in my book this is not called load balancing, rather it is known as migration or fail-over. It is a function available in the virtual machine operating system. One example of where to read about this is here:

http://pubs.vmware.com/vsphere-51/i...UID-3EE13ED8-172F-4560-B806-1E342AD7C486.html

Typically I would expect the cluster of servers to share common disk storage in a SAN or similar. If one server stops, then all data is accessible from the other servers.

I am not sure this would be either easy or inexpensive to do on a farm of mac servers.

PS: in my book, load balancing is typically when several servers run the same applications, ie several servers runnig web servers to same site. An external "load-balancer" then sends the request to the at the moment least loaded webserver, in effect balancing the load between the different servers.

If you're using Open Directory you will simply make one master and the rest replicas.

Load balancing is impossible on OS X server for pretty much everything. OD can do failover by creating replica servers, which is fairly easy to do.

However it can be done in linux
