CHAPTER 1 PRIMEQUEST Overview
• Free resource allocation
If CPUs, memory, and I/O resources have fixed connections, resources may
sometimes be used ineffectively. The flexible I/O mechanism enables CPUs,
memory, and I/O resources to be allocated as required according to the operation
mode to reduce costs.
• Reduced mean time to repair (MTTR)
If an SB fails, use of the flexible I/O mechanism and a reserved SB enables system
recovery simply with a reboot, thereby significantly shortening the MTTR.
The MTTR is the average time necessary for recovery of a faulty computer. It is the
period in which the faulty computer does not operate before it is repaired. The shorter
the MTTR, the easier the maintenance and repair.
Free resource allocation with the flexible I/O mechanism
The flexible I/O mechanism enables flexible use of hardware resources. Specifically,
SBs and IO_Units are freely connected by the flexible I/O mechanism in the crossbar,
and the flexible I/O mechanism provides diversity and flexibility in such connections.
shows an example of the flexible I/O mechanism and partition
configuration.
Note:
The lines in the crossbar represents connections between SBs and IO_Units.
