Hi,
Need your help on this:
According to MS: adding multiple Asynchronous Service servers can significantly improve fault tolerance and further boost performance(http://technet.microsoft.com/en-us/library/gg197607.aspx).
The question is how significantly it will be improved? for example, can we meet 99.9% service availability target if we have 2 separate instances of the asynchronous service? if not, how many separate instances we need then to meet 99.9% availability target ?
Your answer/comments is greatly appreciated!
Frank
