Great stuff, I strongly recommend NLB for ISA/TMG deployments so having the same potetial for UAG is great news...

Most times an IAG configuration is made up of not only changes in the GUI but also files that that are modified, added, or deleted. Does the UAG array manager take into account propogating file level configurations between nodes?

Yes Mark,

UAG array takes care of all the configuration, including files, as long as they are saved in the right CustomUpdate folder as specified here:

Does it make sense removing the second machine from the "Managed Server Computers” again?

Also information is missing which credentials should be used to join the array. Are the credentials just used to join the array or are they used permanently?

Hi guys,

How many NLB-nodes we could have at UAG-array?

Thank you in advance

Best regards,

Alexey Goldbergs

Hi there,

What load balancing algorithm does NLB for UAG support? Only Round Robin? Is it possible to implement a failover only scenario (one array member is only standby)?

Best regards

Thomas

UAG is using Windows Server NLB mechanism, and the distribution of traffic is not pure round-robin. You can read more on the load balancing algorithm in this article:

http://technet.microsoft.com/en-us/library/cc738464(WS.10).aspx

With regard to failover, traffic is distributed among all nodes - no node in a standby - unless it was manually suspended or stopped sending NLB heartbeat.
