Currently our setup is bound to a single ISP , our production application domain urls instance are bound to that single ISP. So we are heavily depend on single ISP. Hence we are planning for redundancy at ISP Level and wih Secondary ISP. Now we would required F5 solution to handle redundancy between ISPs without affecting domain change or IP change at our end. Also we would like to local load balancing of servers with F5. At present we have f5 1600 ltm for server load balancing. In case of ISP1 failure, applications hosted on our network should be available for end users through ISP2, without any disturbance/downtime/Major Changes. Once this is successful, we are planning for DR site for the same hosted applications. In case of DC site failure, the hosted applications should be available for end users through DR site, without any disturbance/downtime/Major Changes. Attached sample network setup of me. appreciate to advice of design to handle isp redundancy and server using F5 1600.
TechgeeegHi Rizwan,
The answer of your requirement is the F5-GTM this will take care of the ISP level redundancy and once you will have another DR site it will take care of the DC level redundancy as well. F5-GTM-1600 is an answer for you it has a throughput of 1Gbps if you have LTM 1600 and its fulfiling your requirement then yes the same model of GTM is enough for your network. For any other detail you may contact me.

Rizwan_77594hi tech,
I understood that license to be activated to enable the present ltm 1600 to act as ltm+gtm combo device. But , i am unable to undertand where should i position the device, and how to do isp and server load balancing. would require some docs, or deployment examples from you- TechgeeegNo you don't have to activate the license on LTM-1600 for it to act as GTM.... Technical details wise I prefer you to take GTM as a separate HW Appliance which will place just after your ISP1 & ISP2 routers so the connection will be like this...
ISP1 Router
--------- GTM ----- Firewall ---------Core Switch---Servers
ISP2 Router
Also on the core you will have LTM connected....
I hope this answers your question - Rizwan_77594Thanks,I undertood now. Can we have GTMs in HA pair?
I appreciate if you can upload/send me implementation document of above setup would be much helpfull.
PS : In F5 website, it is mentioned gtm is an add on component to LTM, and can co-exist. - TechgeeegYes it's highly recommended to have GTM as a HA pair. Yes this is true that GTM is an add on component on LTM but due to their placement I have always seen them running separately.
It may not be possible for a new person to Carry out the complete installation of GTM succesfully so I prefer you get some professional services. You may source me out the installation services... ;)...
