Node

The term "node" in this document refers to CPUs that run the Comware system and require process backup. For example, if a device has multiple MPUs, each MPU has a node. If the device has multiple access controller modules, each access controller module has a node. If the device has multiple firewall modules, each firewall module has two CPUs that run the Comware system. One CPU is for data switching, and the other is for security services that are required to be backed up. The CPU for security services is a node.
