GTM instead of LTM HA

Hi,     I'm looking at deploying a new environment with dedicated 6900 LTMs and have concerns about the single point of failure they represent in an HA config. Sure it's "HA" and it's two machin...

If you're worried about availability, obviously 2 pairs will be better than 1. Would these be placed in a manner that would require you to use network failover or would you be using voltage failover?

 

 

I've been running 6900s for a couple years now and have been plenty satisfied with them. I can definitely say though that I have had issues with network failover but with MAC Masquerading, can get away with it. With that said, you will obviously have a shared config on a single pair making human error that much more of a risk.

 

 

If you have the money, I'd definitely go with 2 pairs. I haven't played with 6400s but have played with 6800s and can say 6900s are much more stable so I wouldn't be too concerned on that front.
