Re: standby adapter
I am looking for the answer to the question of why our customer is not actively using two adapters. what do you think I should answer this question thanks

I answered that above: Rather than having both adapters as active, you have a hot standby - meaning that performance in the event of a failover will be predictable (assuming vmnic0 and vmnic1 can offer...

i am curious about a topic. when i use active-active mode vSwitch configured. There are 10 virtual servers. Which active nic does it use if I open these virtual servers respectively? Is there a rule?
View ArticleRe: active-active adaptor
It will roughly distribute them across those vmnics. There is no hard, definitive rule as to which one will be used. Importantly, it will not attempt to "balance" the load based on the utilization.
