non http GSLB with failover pairs in each DC

Hi guys,

I'm fairly confident that it's possible to use GSLB between two datacenters for non http traffic. My question is, can you do this while having redundant CSS in each datacenter?

Thanks

definitely possible. The easiest solution would be to use box-to-box redundancy.

Gilles.

So I would use box-to-box redundancy in each datacenter, then VIP redundancy between datacenters?

no.

Bob-to-box and vip redundancy are done locally.

You have to select one of them and in this case, the easiest solution would be box-to-box.

Between the data centers you use GSLB.

Just to make sure I understand...

You can either configure box-to-box redundancy or VIP redundancy within the datacenter (locally) -- not both. Between the datacenters you use GSLB.

YOu mentioned that the easiest solution on the local level would be box-to-box, but could you use vip redundancy locally if you still wanted local services to be redundant within each datacenter? Basically, can you mix it so that you have some services redundant across datacenters, but other services redundant within datacenters?

Thanks again,

I assume you can.

The problem is that since you have 2 devices in each datacenter, you need to configure GSLB between all 4.

While if you have box-to-box redundancy, one device in each datacenter is dormant and GSLB is just used as if there was only 1 device.
