Bluecoat proxies with active-standby LTMs

Hi,

We have a couple of LTMs that will act in active-standby mode for our cache farm project where we will be implementing explicit proxy solution.

 

I would request your advice for connecting these Bluecoat proxies to the LTMs. I want these proxies (3-4 in in number) to be connected directly to both the LTMs. In case the primary LTM goes down, the user traffic should seamlessly shift to the secondary LTM.

 

I know that we can connect the proxies to a switch which will in turn connect to the LTMs but I do not want to have another device between LTMs and proxies. Which solution is better and what are our options here?

 

Your advice will be highly appreciated.

 

Thanks

    you can directly connect proxysg to bigip. since there are two bigip, u have to divide proxysg by two.

     

     

    anyway, if i were you, i would connect all proxysg to stack switch which then connect to bigip using link aggregation.

    Hi Ahmer,

     

    I am in full agreement with nitass that L2 switch between the proxy and LTM is strongly recommended.
