Controller and Port Worldwide Names
(Node IDs)
A worldwide name—also called a NODE_ID—is a unique 64-bit number assigned to
a subsystem by the Institute of Electrical and Electronics Engineers (IEEE) and set by
Compaq manufacturing prior to shipping. As shown in Figure 3–9, it refers to the
shelf the controllers sit on, and the worldwide name is stored in the controllers’
memory for the benefit of the shelf. The worldwide name assigned to a subsystem
never changes.

Each subsystem’s worldwide name ends in zero, for example 5000-1FE1-FF0C-
EE00. The controller port IDs are derived from the worldwide name.
