pls mention e.g. ASIC 1-- port 0-8 , I have to do localization of high intensive I/O storage and servers for migration from 12K to 5300, though I maintain port groups, I will see the ASIC too.

--->>> pls mention e.g. ASIC 1-- port 0-8 .....I have to do localization....
you cannot anything localized trough the ASIC's
you question don't make any sense.
as mentioned, 16 User Port per ASIC's

Why can not I do the localization according to the ASIC?
16 user port per ASIC means 5300 has 9 ASICs and 80 ports. is it 0-15 1 ASIC and like this.
e.g. in FC4-32 blade ports 0-15 comes under one ASIC and 16-31 comes under other ASIC. and in FC4-48, ports 0-7, 24-39 comes under one and 8-23 and 40-47 comes under the other .

This example with the Blade here is useless.
Internal links are: 32Gbit/sec between each front and backend ASIC's
with other words all Nine ASIC's are Cascaded the One to another One
This is the reason why you cannot localized anything....

<This is the reason why you cannot localized anything....>
I am a little bit confused. We bought 4 5300s with all the PODs. we have to release 6 3800s and 2 12Ks. If localization is not possible in these SWs.. then I am thinking we should not have gone for these SWs. pls suggest Mr. Techhelp.....
Anyway I have already made plan taking the port groups.
Do you have some doc about 5300 ASICs? pls provide me.

Assuming there are five front-end ASICs with 8 ports on each one to connect to the four back-end ASICs, there could only be 2 ports (16-Gbps) to each back-end ASIC, not 32-Gbps. Did I misunderstand your comment? Also, I don't see why there cannot be local switching for the ports attached to the same front-end ASIC.
