Ok, so currently we have a HA pair of LTMs with ASM modules that load balance web servers as we are a small hosting company.
We recently just purchased equipment to build out a DR site for our websites and along with that purchased a GTM for each site, and two BIG-IP boxes with EdgeGateway, WebAccelerator, and WAN Optimization to go along with our curent HA pair of LTMs.
Configuring the EdgeGateway and WAN Optimization is pretty straight forward. My main question is concerning the design and integration of the GTM, Web Accelerator and LTM piece.
Seems like every doc out there on WebAccel configuration assumes you are running it on the same box as your LTM. For us this is not the case as our GTM, LTM and WA all are on different BIG-IP devices.
Currently we have a pretty simple design as our Firewall NATing to the VIPs on the LTM and the Pool Members behind that.
When we integrate the WA it looks like we will have to create new VIPs for each Website on the WA Box and then make their pool members the current VIP IPs for the website on the LTMs. I was hoping there was someway around having two VIPs for each site since when we add a new one we will now have to do it in two places. Then as we grow it will get confusing since every website will have like 5 IPs(Wide IP, External IP, WA VIP, LTM VIP, Server Host IP)
Anyone have any insight on this? The only doc I could find that was even close to it was how to integrate multiple stand alone WAs behind a LTM(s).
