multiple pools with one virtual server
Situation:
Two data centers, A and B. Each one has a load balancer. Each load balancer has a virtual server. Each virtual server points to a local pool of servers.
So, virtual server A on load balancer A uses pool of servers A, and v.s. B uses pool B. So far so good.
I am trying to find out whether a virtual server can have more than one pool, and switch to the "backup pool" if the primary pool goes down. Basically, add pool B to virtual server A (on load balancer A), and have it take over the virtual server if pool A goes down.
Is there a way to do that?
The reason why I'm trying to do it:
The two data centers are disaster recovery sites, and the clients are sent to one site or another based on DNS. But some clients (Explorer) ignore the DNS TTL so remain stuck on one site.
So, if clients are stuck on site B while they should really go to site A, I would like the load balancer B to automatically add pool A to virtual server B - this way the clients are automatically routed internally to the right servers. This assumes the internal routing between sites still works.
