And now for something rather pretty!
In Data ONTAP 8.2.1, for the new FAS8040/8060 models, there is the option to use 4 cluster interconnects per node.
Below is a diagram that shows how we connect this up to CN1610 cluster switches for a 2-node FAS8040A. Before I present the diagram, here’s the logic:
e0a and e0b share an ASIC (let’s call it ASIC 1*)
e0c and e0d share an ASIC (let’s call it ASIC 2*)
*ASIC = Application-Specific Integrated Circuit
So, to avoid an ASIC failing and taking out both connections to a cluster switch, we have:
Port 1 on ASIC 1 (e0a) to Cluster Switch 1 - Port 1
Port 1 on ASIC 2 (e0c) to Cluster Switch 2 - Port 1
Port 2 on ASIC 1 (e0b) to Cluster Switch 2 - Port 2
Port 2 on ASIC2 (e0d) to Cluster Switch 1 - Port 2
Then rinse and repeat for subsequent nodes.

What is this diagram type? I looked in creately diagram community, it doesn't add up.ReplyDelete
