SRDF and IP addresses
Hello,
4 IP addresses are required on both side to implement SRDF, are the 4 IPs mandatory ? Why ?
How does SRDF work regarding IP, in case there is a router or a switch between the 2 sites ?
Thanks for your answers

Consty,
Each Gig-E port requires its own IP. Presumably, each of your arrays has four Gig-E ports, so you need four IP addresses per array.
If there is a router/switch between sites (which there should be), the arrays will form a "mesh" of TCP sessions between each other -- each port from "Array1" will establish a TCP session to all ports on "Array2." So with four ports/IPs per array, you'll end up with sixteen TCP sessions, and the arrays will balance replication traffic across these sessions.
Thanks,
- Sean

Thanks a lot for your answer !
What will happen if we only use 2 IP ? Will it work somehow or not ?
Thanks

Consty,
2 IP will work if you only use 2 out of 4 directors. I think Sean has already explained this

Hello,
Thanks all of you for your answers.
My next question is to know the minimum bandwidth used for asynchronous SRDF .
Thanks
