Open-Faced Compute and Storage Rack-Wall for Higher Device Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rack systems with vertical supports at repeating intervals lead to wasted space and reduced computing or storage capacity due to the arrangement of standard hard disk drives, resulting in inefficient use of data center space.
Innovation Solution
A rack-wall computing and/or data storage system with an open-faced mounting structure that eliminates front-facing vertical supports, allowing for greater device density and flexible enclosure sizes, enabling hot-serviceable chassis and improved air flow by increasing gaps between components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vertical supports are placed at repeating intervals in conventional rack systems, then structural stability is provided, but space is wasted and device density is reduced
Solution Approach 1:
The patent removes the front vertical support posts from the rack system, extracting the unnecessary structural element that was causing space waste. The rear vertical supports remain to maintain structural stability, while the front opening allows direct access to devices and increases usable space for mounting components.
Solution Approach 2:
The patent transitions from a traditional four-post rack structure to an open-faced structure by eliminating vertical supports in one dimension (the front), while maintaining the horizontal shelving dimension. This dimensional change allows devices to be mounted closer together and improves air flow paths.
2Reliability
If standard off-the-shelf hard disk drives are used, then cost-effectiveness is improved, but space utilization is reduced due to arrangement constraints
Solution Approach 1:
The patent enables flexible and dynamic arrangement of standard hard disk drives within the open-faced rack enclosures. The removed vertical supports allow devices to be positioned in optimized configurations rather than being constrained by fixed vertical post locations, maximizing space utilization while maintaining cost-effectiveness of standard drives.
3Reliability
If vertical supports are present at repeating intervals, then structural support is provided, but air flow is restricted and cooling efficiency is reduced
Solution Approach 1:
By removing the front vertical support posts, the patent eliminates obstacles that blocked air flow paths. This extraction creates unobstructed channels for air to move through the rack, improving cooling efficiency and reducing the energy required for thermal management while rear supports maintain necessary structural integrity.
4Reliability
If conventional rack systems with vertical posts are used, then structural integrity is maintained, but accessibility for maintenance is reduced
Solution Approach 1:
The removal of front vertical support posts creates an open-faced structure that provides direct access to devices mounted in the rack. Technicians can now easily reach and service components from the front without obstruction, while the rear vertical supports preserve the necessary structural integrity of the entire rack system.
Data Source
AI summary
A rack-wall computing and/or data storage system includes computing and/or storage devices mounted in enclosures; the enclosures are also mounted in one or more device chassis that fit into one or more vertical slots of an open-faced mounting structure. The mounting structure is free of vertical or horizontal supports on a front side, which allows for a greater density of enclosures (and therefore computing or storage devices) to be mounted in a given volume of space, as compared to conventional racks that include vertical supports at repeating intervals (e.g., every 24 inches). Also, a given device chassis can be extracted from the mounting structure, via the open front face, using a rail system, wherein in the extracted position, the enclosures are accessible for servicing on at least two sides (e.g., front and back).
