I'm currently replacing an existing Brocade SAN with a 9134 based one (not a big site).
Now the 9134 is also available in a stacked config (buying through IBM) which consists:
1 x 9134
2 x 10Gb port activation Licenses
2 x 10Gb CX4 copper transceivers
1 x CX4 Cable
You obvously buy these in pairs to stack a pair of switches, I've looked around, but i'm still not 100% what you actually get.
Do you still have two switches and a fast ISL or does it appear as 1 bigger switch? IF one big switch is one the master and thats the one you connect your ethernet management cable into?
