I need your support for the following problem.
I have a SAN Fabric with 4 Brocade Switches:
ID: 2 (Principal)Model: Brocade 200EFoS: 5.0.1b (upgradable to 6.2.2f)
ID: 1Model: 3800FoS: 3.1.2a (upgradable to 3.2.1c)
ID 51Model: Brocade 300FoS: 6.1.0a (upgradable to 7.x)
ID 100Model: Brocade 300FoS: 6.2.0a (upgradable to 7.x)
Is it possible to have these switches with different FoS in the same fabric?Do you know if there are some compatibility issues?
Brocade 3800 reached EOSL a few years ago, so it does not appear in any compatibility matrix since it is not supported anymore. On the other hand, all the FOS releases mentioned are a little bit too old, anything below v6.2.1 should not be used...
Once said this, connectivity between Brocade 200E and 300 should not be an issue (although I do recommend you to upgrade FOS on both switchs to 6.2.2f and 6.4.3b respectively). When it comes to 3800, I cannot guarantee that it will work, but you can try, I reckon that the switchs will merge but with such a difference of versions, anything could happen...
