Storage Tray Slot Mechanism for Power-Loss Data Flush
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As data processing capacity and performance increase in server devices, the power consumption also rises, leading to potential power loss issues that can compromise data integrity, necessitating effective data protection measures during power outages.
Innovation Solution
A storage device with a tray that moves along a slot during power loss, combined with a host device's power supply unit and a baseboard management controller module, ensures stable operation by providing auxiliary power and data flush commands to secure data integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data processing capacity and performance are increased in server devices, then data processing capability is improved, but power consumption increases leading to potential power loss issues
Solution Approach 1:
The tray is designed to move along the slot in advance when power loss is detected, creating a time buffer before complete power failure. This preliminary mechanical action extends the operational window for data flushing from volatile memory to non-volatile storage, allowing the system to complete critical data protection tasks even as power deteriorates.
2Reliability
If power loss protection measures are implemented, then data security is improved, but device complexity increases
Solution Approach 1:
The tray acts as a mechanical intermediary between the host device and the storage device. When power loss occurs, the tray moves along the slot to physically separate or reposition the storage device, creating a mechanical buffer that extends the time available for data protection. This intermediary mechanism provides a simple yet effective way to buy time for data flushing without requiring complex electronic control systems.
3Loss of time
If the tray moves along the slot during power loss, then data flush time is extended, but mechanical reliability requirements increase
Solution Approach 1:
The system transitions from a static configuration to a dynamic one during power loss events. The tray is designed to move along the slot only when needed, transforming the storage device from a fixed position to a movable position. This dynamic adjustment extends the data flush time by creating additional time buffer, while the mechanical design ensures the movement is simple and reliable without requiring complex actuators or control mechanisms.

AI summary
A storage device includes: a substrate including a first surface which extends in first and second directions intersecting each other; an electronic element disposed on the first surface of the substrate; a connector connected to a host device; a tray on which the substrate is mounted; and a guide frame disposed in the tray to support the substrate and having a slot formed to extend along the first direction to a first length, in which, when a loss of power provided from the host device occurs, the tray moves along the slot by the first length.
