How Automatic Client Upgrade Hammered Our Primary Server

Recommended Posts

Folks,

 

My first experience with Automatic Client Upgrade (post R2 SP1) is not a good one...

 

After enabling this in live, even with the maximum 31 day upgrade window, our Primary server jumped to 95% network utilisation - things returned to normal shortly after disabling it. Following a brief investigation this morning I think I know why... OK, we were expecting Scheduled Tasks to be created across all our clients on day one. What we didn't expect was that client source would be pre-staged to the PCs at the same time! To add insult to injury, as this deployment doesn't employ the usual caching methods the 1E Nomad software we use to reduce server load was bypassed too... For now we are going to use the old right-click-a-collection-and-reinstall-client method to deploy it gradually ourselves.

 

What's the point in being able to increase the window to 31 days if the server is going to push client executables to every PC on day one? I still find it hard to believe it works like this but this is what I'm seeing. Note, only ccmsetup.exe is mentioned in the log but I saw an up-to-date 27Mb MSI in the same folder... Anyway, see the log snippet below.
