How Nodes handle a data request -Isilon
Can some one explain me understand how Isilon - Nodes handles a data request?
As per the Isilon documentation each node in a cluster is a peer and any node can handle a data request.My question is lets say we have an
8-node cluster where 2 nodes(Node1, Node 2) cpu utilisation is 90%.does the new data requests from clients connected to node-2 is still handled by node2 or other nodes? Also is there any parameters like if a node reaches certain percent busy, user requests connected to that node would be handled/processed by its peer nodes?

yes the Initial request is handled by node2.
But the data resides also on other nodes (depending on your protection Setting) so a request will be handled (userfaced) by node 2 but the data will be read also from other nodes (i.e. 4 + 7 + 8) in the backend.
You could modify the incoming Connections on cpu-cycles so you don't do a roundrobin but a cpuload-Balance. This can be done in the smartconnect settings and is an option only available for smartconnectadvanced license.
