One-Third Width IT Sled Block Chassis for Rack Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information handling systems face limitations in scalability and flexibility, particularly in accommodating different widths of IT gear within a standard rack, which restricts concurrent support of full-width, half-width, and one-third width sleds, leading to constraints in servicing and operational efficiency.
Innovation Solution
A modular, expandable rack-based information handling system that incorporates a block chassis design allowing for the insertion of one-third width IT sleds, enabling side-by-side placement and direct power coupling, along with block-level control, to support hybrid combinations of compute and storage nodes, thereby increasing compute density and allowing for concurrent operation during cold storage servicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If full-width server sleds are used in a standard rack, then the rack structure is simple and standardized, but the flexibility and scalability to accommodate different widths of IT gear is reduced
Solution Approach 1:
The rack is divided into multiple rack units, each rack unit capable of accommodating IT gear of different widths (full-width, half-width, one-third width). This segmentation allows the rack to be configured flexibly to accommodate various IT gear widths while maintaining a standardized overall structure.
Solution Approach 2:
Each rack unit is designed with universal characteristics to accommodate multiple types of IT gear (full-width, half-width, one-third width sleds). The standardized rack unit structure with adjustable components enables it to serve multiple functions and accommodate different configurations without requiring entirely different rack designs.
2Quantity of substance
If cold serviceable storage IT gear is selected for the full-width server rack, then storage capacity is improved, but computing IT gear necessarily does not operate when the full-width server rack is being cold serviced
Solution Approach 1:
The rack is divided into separate rack units that can be serviced independently. Storage IT gear in one rack unit can be cold serviced without affecting computing IT gear in other rack units, allowing computing operations to continue during storage servicing.
Solution Approach 2:
The modular rack unit structure acts as an intermediary that isolates the servicing operation to a specific rack unit while allowing other rack units to continue operating. This enables selective servicing of storage gear without shutting down the entire rack system.
3Productivity
If one-third width IT sleds are inserted into the rack, then compute density and configuration flexibility are increased, but the rack and chassis design complexity increases
Solution Approach 1:
The rack is segmented into standardized rack units that can accommodate one-third width IT sleds along with full-width and half-width sleds. This segmentation enables high compute density through compact one-third width sleds while maintaining standardized, manageable chassis design through the modular rack unit approach.
Solution Approach 2:
Different rack units can be configured with different local qualities - some optimized for one-third width sleds to maximize compute density, others for full-width sleds for specific high-performance applications. This allows localized optimization without requiring complete redesign of the entire rack system.

AI summary
Modular, expandable rack assembly physically supports components of information handling systems. Base structure of interconnected panels form volumetric space having front section and rear section, with opposing side panels forming front access space and rear access space, respectively, having width that supports insertion of standard full-width IT gear. Guides are located within interior surfaces of opposing side panels at the front section to rear section. Block chassis has frame that provides block height to enable insertion of at least one layer of up to N side-by-side fully functional IT gears within block chassis, which in turn is physically inserted into front section of base structure and held in place by opposing guides of opposing side panels. When N is 3, three side-by-side one-third width IT sleds, each containing IT gear, are inserted in respective one-third width IT bays of block chassis.
