1. Storage - how is the shared storage acheived?
By storage replication (preferably with fibre)

If two node,  DRBD may work with a very-very fast link (It works in a 100mbps lan though like campuses with two nodes in very seperate buildings)
 
2. Fencing - any special methods to fence ?
DRC/ILO/ILOM comes to mind
 
3. Max. number of nodes possible in such a setup

I have done it with 4 nodes max

4. any special methods/exceptions/rules to setup this cluster?
 
 
Pointers to any material in this regard will be great. Thanks much in advance.
