Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional disk array enclosures face severe thermal issues due to blocked airflow during maintenance, which can lead to increased temperatures and potential damage to disk devices.
Innovation Solution
A cap design with vents and windshield bars is implemented, where the vents abut against the upper surface of storage devices and the windshield bars cover gaps between adjacent devices, forming a grid structure to maintain airflow and prevent leakage, ensuring optimal thermal performance even during maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cap is closed to protect storage devices during maintenance, then device protection is improved, but thermal performance deteriorates due to blocked airflow
Solution Approach 1:
The cap is segmented into multiple functional elements: solid portions for protection, and vent portions with through-holes for airflow. This segmentation allows the cap to simultaneously provide device protection and maintain thermal performance by enabling cooling airflow to pass through the vent portions while the solid portions protect the storage devices.
Solution Approach 2:
Different portions of the cap have different properties: the solid portions provide protection while the vent portions with through-holes provide airflow channels. This local quality differentiation allows the cap to perform multiple functions - protection and cooling - simultaneously, resolving the contradiction between device protection and thermal performance.
2Ease of operation
If gaps between adjacent storage devices are left open for accessibility, then ease of operation is improved, but thermal performance deteriorates due to airflow leakage
Solution Approach 1:
The windshield bars act as intermediary elements that span across the gaps between adjacent storage devices. These bars prevent airflow leakage through the gaps while maintaining accessibility to the storage devices, thus resolving the contradiction between ease of operation and thermal performance by mediating the airflow path.
3Temperature
If vents are added to the cap for airflow, then thermal performance is improved, but device protection deteriorates due to potential exposure
Solution Approach 1:
The cap has different local qualities: solid portions for protection and vent portions with controlled through-holes for airflow. The vent portions are designed with specific aperture sizes and positions that allow cooling airflow while the solid portions maintain device protection. This local quality differentiation resolves the contradiction between thermal performance and device protection.

AI summary
Various embodiments of the present disclosure disclose a storage system. The storage system comprises: at least one storage device array enclosure, each of the storage device array enclosure accommodating storage devices, which are arranged in columns and have gaps existing between adjacent storage devices; each storage device array enclosure includes a cap for covering accommodated storage devices; the cap includes vents and windshield bars, such that when the cap is in a closed state, the vents abut against an upper surface of the corresponding storage devices and the windshield bars cover the gaps between adjacent storage devices. The design of the cap in the storage system of the present disclosure can ensure that during the maintenance of the storage devices in the storage device array enclosure, the cooling airflow is capable of passing through the vents of the opened cap and then entering inside of another storage device array enclosure above the maintained storage device array enclosure, so as to effectively improve thermal performance inside the storage device array enclosure.
