NICs for Private Interconnect redundancy

Steve_74May 31 2012 — edited May 31 2012
DB/Grid version : 11.2.0.2
Platform : AIX 6.1

We are going to install a 2-node RAC on AIX (that thing which is almost good as Solaris )

Our primary private interconnect is
### Primary Private Interconnect
169.21.204.1      scnuprd186-privt1.mvtrs.net  scnuprd186-privt1 
169.21.204.4      scnuprd187-privt1.mvtrs.net  scnuprd187-privt1
For Cluster inteconnect's redundancy , Unix team has attached an extra NIC for each node with an extra Gigabit-ethernet switch for these NICs.



###Redundant Private Interconnect attached to the server
 
169.21.204.2      scnuprd186-privt2.mvtrs.net  scnuprd186-privt2  # Node1's newly attached redundant NIC
169.21.204.5      scnuprd187-privt2.mvtrs.net  scnuprd187-privt2  # Node2's newly attached redundant NIC
Example borrowed from citizen2's post


Apparently I have 2 ways to implement cluster inteconnect's redundancy

Option1. NIC bonding at OS level
Option2. Let grid software do it

Question1. Which is better : Option 1 or 2 ?

Question2.
Regarding Option2.
From googling and OTN , i gather that , during grid installation you just provide 169.21.204.0 for cluster inteconnect and grid will identify the redundant NIC and switch. And if something goes wrong with the Primary Interconnect setup (shown above) , grid will automatically re-route interconnect traffic using the redundant NIC setup. Is this correct ?


Question 3.
My colleague tells me , for the redundant Switch (Gigabit) Unless I configure some Multicasting (AIX specific), I could get errors during installation. He doesn't clearly what it was ? Anyone faced Multicasting related issue on this ?
