4 x Unity failover pairs for 20k seats

[askq2forum]

Hi we have to provide a VM deployment for 20K seats. Will 4 x Unity failover pairs with exchange on the secondary servers be ok for this(5k seats per pair). They will form 1 domain with 2 additional servers acting as dc's/gc's within the domain.

thanks...Jag

are you sure you can put exchange on the secondary in 4.x? I thought that was 5.x.

Rip, thanks for reply, you are correct re Unity 5

I need to clarify - we are proposing 4 pairs of Unity 5.x with Exchange on the secondary server.They will form a single domain with another 2 servers as dc/gc's. Just want opinion if thats ok from a design point.

Cheers...Jag

It sounds solid to me just as long as the networking speed/connection is good.

Just for my knowledge, are each pair going to be in a different physical location?
