Pre-boot OS Installer Standby State for Data Center Boot Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing boot process for computing devices is time-consuming, especially for large numbers of devices being provisioned or re-provisioned in a data center, due to the lengthy initialization routines and OS installation processes.
Innovation Solution
The proposed solution involves a pre-boot process that initializes the computing device into a standby state, where the OS installer is loaded and waits for a command to resume the boot process. This allows the initialization procedures and OS installer loading to be completed before the actual boot request is received, significantly reducing the overall boot time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the traditional boot process is used to initialize computing devices, then the devices can be started up, but the process takes several minutes which reduces productivity
Solution Approach 1:
The patent applies preliminary action by performing the OS installer loading and initialization procedures before the actual boot request is received. The computing device is pre-booted into a standby state where the OS installer is already loaded and ready, so when the boot request arrives, the device can quickly transition to the operational state without performing the lengthy initialization routines at that moment.
2Loss of time
If the boot process is accelerated by pre-loading the OS installer, then boot time is reduced, but power consumption increases due to devices remaining in standby state
Solution Approach 1:
The patent applies periodic action by managing the standby state of computing devices in a periodic manner. Devices are pre-booted into standby state in advance, remain there during a waiting period, and then quickly transition to operational state when boot requests are received. This periodic cycling between standby and operational states allows the system to balance power consumption with boot speed requirements.

AI summary
Techniques for booting a computing device are disclosed. An example method includes, in response to powering on or rebooting a computing device, performing a pre-boot process comprising loading an Operating System (OS) installer into storage of the computing device and executing the OS installer. The method also includes entering, by a processing device executing the OS installer, a standby state after performing the pre-boot process. The method also includes in response to receiving an activation instruction, exiting the standby state and installing an operating system of the computing device.
