Ring topology with 4 Brocade 300

Hi,

I have two Brocade 300 connect together in fabric. Can I expand this fabric by connect more two switch in order to make a ring topology for redundant?

All my switch have fabric lisence.

Thank you.

Sure. You can also create a mesh if you want for super extra redundancy.

If you plan on much traffic make sure you connect with trunks and consider exchange-based routing.

Make sure the Domain IDs are unique among all switches you plan to interconnect before connecting them Smiley Happy

Re: Ring topology with 4 Brocade 300

can my ask what is the reason why you want to create Ring/Mesh Topology ?

 

keep in mind such a Topology is very difficult to Expand.

 

since you have in Total 4x Switch, I would create a Dual Fabric

 

Fabric_A: = Switch_1 and Switch_2

Fabric_B: = Switch_3 and Switch_4

 

is my opinion as per my experience.

Dear TechHelp24,

I have only a FC path from storage to switch_4. If server connect to switch_1 or switch_2, It can not see Storage? All my servers only have a FC port.

So, I think a ring topology is suitable for my system.

Please tell me more your advice

Thank you

--->>>I have only a FC path from storage to switch_4.

 

if you connect the Storage Port to a ONE Switch only, you have a Single Point of Failure,

 

we assume one day failed this Switch, all Server and Connectivity have don't access to the Storage.

 

Of Course, most modern Storage System are equipped with FC Controller Total within 4 FC Port, in suche case you can safely Create a Dual fabric as mentioned in my preview Post

 

The same, i assume all you Server are equipped with DUAL Port HBA.

 

In such case I would insist to encourage you to Create a DUAL Fabric

 

Fabric_A:

 

Switch_1

Switch_2

 

Fabric_B:

 

Switch_3

Switch_4
