Blade Server Storage Expansion via Middle Plane Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blade server systems face limited storage capacity due to the size of internal hard drives, necessitating external storage systems that occupy space and require unnecessary lines, while smaller enterprises often have underutilized server racks with idle slots.
Innovation Solution
An expandable storage apparatus integrated within the blade server system, comprising a storage system, control module, and connector to the middle plane, allowing direct access and eliminating the need for external storage systems by using a JBOD or RAID system with hot-swappable capabilities and dynamic allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If external storage systems are connected to increase storage capacity, then storage capacity is improved, but space occupation and line complexity increase
Solution Approach 1:
The patent merges the storage system with the blade server system by integrating storage modules into the existing rack structure. The storage modules share the same physical space and power infrastructure as the blade servers, eliminating the need for separate external storage systems and reducing overall space occupation.
Solution Approach 2:
The rack structure is designed to serve multiple functions: it houses both blade servers and storage modules, provides power to both, and offers a unified management interface. This multi-functionality allows the same infrastructure to support both computing and storage needs, reducing the need for additional dedicated storage infrastructure.
2Quantity of substance
If external storage systems are connected to increase storage capacity, then storage capacity is improved, but the amount of lines and connections increases
Solution Approach 1:
The storage modules are integrated into the blade server system's existing connection infrastructure. They share the same backplane, power distribution, and management interfaces as the blade servers, eliminating the need for separate connection cables and reducing line complexity.
Solution Approach 2:
The patent introduces a storage controller or management interface that acts as an intermediary between the blade servers and storage modules. This intermediary consolidates multiple storage connections into a unified interface, simplifying the connection architecture and reducing the number of individual lines required.
3Reliability
If blade servers are removed for maintenance or replacement, then system reliability is improved, but system downtime occurs
Solution Approach 1:
The patent implements hot-swappable blade server design, allowing servers to be removed and replaced without shutting down the system. The redundant power supplies and modular architecture enable seamless server replacement, maintaining system operation during maintenance activities.
Solution Approach 2:
The system allows blade servers to be discarded (removed) and recovered (replaced) dynamically without affecting overall system operation. The modular design enables individual server replacement while the system continues to function, and the same physical slots can be reused for new servers.
Data Source
AI summary
An expandable storage apparatus for a blade server system is provided. In one preferred embodiment of the invention, the storage apparatus inserted within a blade server system comprises a storage system for storing desired information which can be accessed by the blade server system; a control module to control access to information stored in the storage system; and a connector being connected to a middle plane of the blade server system, wherein the storage apparatus is effectively coupled through an input/output module and a middle plane to a blade server within a single blade server system eliminating the need to connect the blade server system to an external storage system.
