Sliding Disk Array Enclosure Mount for Dense Serviceable Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-scale storage systems face challenges in achieving increased drive density while maintaining full serviceability and efficient cooling, as existing systems often compromise on access and airflow due to the stacked configuration of disk array enclosures.
Innovation Solution
A sliding mount system that allows two disk array enclosures to be mounted in the same space as a single enclosure, enabling them to be positioned closely together and easily slid out for service access, while maintaining a common orientation for airflow and cabling management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If two DAEs are mounted in the same space using a sliding mount system, then drive density is increased, but serviceability access becomes restricted
Solution Approach 1:
The patent applies the dynamics principle by implementing a sliding mount system that allows DAEs to transition between two positional states: a first position for normal operation with full serviceability access, and a second position that increases drive density. The mounting system includes sliding mechanisms that enable the DAE to be dynamically repositioned along a sliding path, allowing operators to switch between operational configurations as needed.
2Area of stationary object
If DAEs are mounted in close proximity to increase density, then space utilization is improved, but airflow and cooling efficiency may be compromised
Solution Approach 1:
The system dynamically adjusts the spatial relationship between DAEs by allowing them to slide between positions. When in the first position, DAEs are spaced to maintain optimal airflow channels for cooling. When sliding to the second position, the system prioritizes density while the airflow channels remain designed to accommodate the compact configuration, ensuring cooling efficiency is maintained across both operational states.
3Adaptability or versatility
If a sliding mount system is implemented to enable position changes, then serviceability and density are improved, but device complexity increases
Solution Approach 1:
The mounting system is segmented into modular components including sliding mechanisms, mounting brackets, and positioning guides that can be independently assembled and maintained. This segmentation reduces overall system complexity by allowing each component to be optimized separately and facilitates easier serviceability of the mounting system itself.
Solution Approach 2:
The sliding mount system is designed with universal features that serve multiple functions: the same sliding mechanism enables both position changes for serviceability access and position changes for density optimization. The mounting system simultaneously provides structural support, positioning control, and serviceability enhancement, reducing the need for separate specialized components.

AI summary
An electronic component housing system includes a cabinet having a front portion and a rear portion; a sliding mechanism mounted within the cabinet; and first and second electronic devices mounted to the sliding mechanism, the first and second electronic devices each having a front end and a back end. The sliding mechanism, in a first mode, enables the first and second electronic devices mounted thereto to be positioned within the cabinet between the front portion and the rear portion thereof, such that the front end of the first electronic device is disposed proximate the front portion of the cabinet and the back end of the second electronic device is disposed proximate the rear portion of the cabinet. The sliding mechanism, in a second mode, enables the first electronic device to be positioned beyond the front portion of the cabinet and the second electronic device to be positioned in a location substantially similar to the position occupied by the first electronic device in the first mode.
