Scalable Boot
The scalable boot project improves system boot/reboot times, having a positive effect on
system availability. Scalable boot benefits mainly high-end systems with large I/O
configurations.
Summary of Change
By performing parallel ioscans, boot time is reduced by 5-95%, depending on the I/O
configuration.
Impact
When a system is booted or rebooted for any reason, it can be brought back on-line more
quickly with scalable boot. Higher-end systems with larger I/O configurations will
realize the most difference in reduced boot/reboot time.
Compatibility
There are no compatibility issues.
Performance
Boot time has been reduced by 5-95%, depending on the I/O configuration.
Documentation
Since implementation is done in the kernel and no user/administrator adjustments are
exported, scalable boot documentation is unnecessary.
Obsolescence
Not applicable.
