CHAPTER 1 PRIMEQUEST Overview

Partition function

The partition function logically divides hardware resources in one cabinet into
multiple systems, and each of the systems operates independently. The maximum
number of partitions depends on the model: up to 8 partitions in the PRIMEQUEST
480, and up to 4 partitions in the PRIMEQUEST 440.
The partition function provides the following advantages:
• Flexible system construction
The partition function can be used to construct multiple business systems in the same
cabinet, thereby enabling flexible system construction.
• Robustness
Hardware protects each partition from being affected by another partition. If a failure
occurs in a partition, the other partitions are not affected by it.
