Supportability of my Central Admin article approaches

Print | posted on Friday, May 08, 2009 4:37 PM

Recently a bunch of people have asked me about the supportability of the approaches to providing “high availability” for SharePoint Central Administration I detailed in my article SharePoint Central Administration: High Availability, Load Balancing, Security & General Recommendations.

This short update is to clarify the situation following discussions with Microsoft Premier Field Engineers on the matter.

Running Central Administration on more than one server in the farm is 100% supported, and indeed a recommended best practice.

Load Balancing Central Administration is 100% supported. And even if it wasn’t it wouldn’t matter as you can simply take load balancing out of the equation and hit one of the machines directly.

Implementing Kerberos Authentication for load balanced Central Administration is 100% supported.

Implementing Central Administration on Port 80 or 443 is 100% supported.

If you are told by someone that the above approaches are unsupported, they are incorrect. Please contact me via this blog and I will follow up with you.

I second you , but I have seen these arguments bubble up number of times in MSDN forums (and else where), and most of the time some one leave comment (that one of the mentioned scenario) is not supported.
I want to provide link to this blog entry as evidence whenever the scenario comes up, off course if you don't mind.

Thanks!

Check the following thread , the poster's who reply at "Tuesday, February 24, 2009 5:42 AM" (its a long thread so you might have to scroll a bit) , pointed that its not a good idea to host the CA on multiple servers.

Quotes from the posting.
--------------------------------------------------------
"As for hosting Central Administration on more than one server -- don't do it. There are some posts out there that talk about it, but I would strongly advise you not to go down that road. Get SharePoint running in a basic setup first before trying to do something like that. It is not a standard configuration and not sure if it would even be supported by MSFT if anything broke."

I do remember there are other forum posts , but do not have exact thread links , I will try to post them to you as I gather them.

Thanks!
