CHAPTER 5
This section describes functions like physical partitioning, Extended Partitioning and flexible I/O.
5.1
Partitioning Function
The PRIMEQUEST 2000 series has a partitioning function, which divides the hardware resources of a
cabinet into several logical systems and operates each divided system independently.
The following section describes the partition granularity which is the partition component. After that, an
example of the partition configuration is given and explained for each model.
5.2
Physical Partitioning (PPAR)
The Physical Partition (PPAR) can configure physical partitions in one cabinet to enable flexible system
configuration and server integration while maintaining a high degree of failure isolation.
In the PRIMEQUEST 2000 series, the partition configuration can be changed with a static configuration
control function .The function for changing the configuration of each partition is triggered by a power-off,
power-on, or reboot. The maximum number of PPAR partitions is listed in the table below.

(*1) In the PRIMEQUEST 2800B3/2800B2/2800B, components mounted in the cabinet can be used
within one partition.
In the PRIMEQUEST 2000 series, physical partitions with any number of resources can be configured in the
granularity unit, in combination of the SB/Memory Scale-up Board and IOU, using flexible I/O mode (*1).

The conceptual diagram of the partitioning function for each model is given below.
