We have a 9980V connected with 2 Paths directly to a Brocade 7500 SAN Router at our production site.
We have another 9980V connected with 2 paths directly to a Brocade 7500 SAN Router at the DR site.

Truecopy synchronous works as advertised between the two sites with a DWDM and Dark fiber link between the two SAN routers.

Except that the InitialResponse Times are of the order to 80 to 100 ms which is unacceptable for Truecopy Synchronous

We also have a similar setup with two SE9985 (NSC55) and two McData 4700 and the Initial Response times are of the order of 4 ms.

Has anyone implemented the Brocade 7500 and Truecopy Synchronous ? If yes can someone post the Inital Response Times please ?

BTW :- A fcping between site A and B comes back in<1 ms
