I don't know if you have heard about IBM Storage v7000 (Storwize).....
Well this my enviroment right now
I have a dual storage controller - v7000 - which has 4 fiber channel cables to each Brocade 3000....switch just have 4 port left each one and we need to add 10 more servers.....
so what is needed to stack o join (not sure about the work) I mean create one big fabric of 4 brcoade 3000.
what are the requirements? ISL? licenses for ISL? anything else?
BTW I was thinking is it needed to stack them? can they work as they are working right now? I mean instead of two independent switch as 4 independent switch?
------- edit 2
I thin 2 switch must be stacked and the othet 2 too in other to have 2 fabrics
thanks a lot

I may have seen some news about it. Looks like it has 8 FC host ports.
As far as I understand your post you now have 4 switches, each has 4 free ports, becoming 16 free ports in total - is that correct?
And you want to cable:
all host ports of the v7000: 8
two ports from each of the 10 new servers: 20
So with my math you're missing 12 ports.
Sounds like to me that you need to get a pair of new switches.
Are you going to need all 8 host ports from the v7000? Maybe 4 is enough? Does the v7000 support direct connectivity? If you really cannot get new switches then perhaps that's a solution in the meantime.

you question is more as confused.
--->>> so what is needed to stack o join....../...... I mean create one big fabric of 4 brcoade 3000.
such config is called Single Fabric.
--->>> what are the requirements? ISL? licenses for ISL? anything else?
In order to ISL TWO or more Switch, all witches in the Fabric must have Fabric License - E_Port -
--->>> I thin 2 switch must be stacked and the othet 2 too in other to have 2 fabrics
as mentioned, if you ISL "stacked" all 4 Switches you get a Single Fabric, in order to create DUAL Fabric for Failover you should ISL just TWO Switches each Fabric e.g.
SWITCH_1 Domain_ID 1
SWITCH_2 Domain_ID 3
SWITCH_3 Domain_ID 2
SWITCH_4 Domain_ID 4

it's going to be something like that
I am missing the ISL and trunking in fact I have to read some to get the understanding about ISL and Trunking
thanks a lot guys

ISL and ISL-Trunking are not the same.
trunking is optional if you want to increase Performance but not mandatory required.
in order to build a Fabric - ISL=Inter Switch Link - you need Fabric License
