What is node.
A node is a group of SAP BusinessObjects Business Intelligence platform servers that run on the same host and are managed by the same Server Intelligence Agent (SIA). All servers on a node run under the same user account.
One machine can contain many nodes, so you can run processes under different user accounts. One SIA manages and monitors all of the servers on a node, ensuring they operate properly.
