1.1 Understanding Nodes, Services, and Roles
The HP XC system consists of individual computers, called nodes, that supply various services.
For example, some nodes provide services that provide networking while others provide services
that allow users to run jobs.
This section describes nodes, services, and roles.
1.1.1 Nodes
Each node of an HP XC system is an individual computer. All nodes of an HP XC system must
be of the same architecture. Some nodes contain their own local storage.
1.1.1.1 Node Types
These are the types of nodes in the HP XC system:
compute nodes Provide the basic services that let users run jobs. Any node in the HP
XC system is capable of being a compute node.
An HP XC system is comprised mostly of compute nodes.
