Solution Overview
Problem
Current information handling systems face challenges in efficiently managing workloads and hot-swapping co-processors in data centers, particularly in maintaining system uptime and reducing the need for physical presence of technicians for maintenance.
Innovation Solution
A system and method for managing workloads and hot-swapping co-processors using a wireless management network that includes a management controller and a wireless management module, enabling out-of-band monitoring and control, secure wireless connectivity, and automated hot-plug operations, allowing for remote management and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If co-processors are hot-swapped in data centers, then maintenance can be performed without complete system shutdown, but system uptime and stability may be compromised during the swapping process
Solution Approach 1:
The system performs preliminary actions by migrating workloads to other co-processors before removing the target co-processor. The management controller identifies suitable target co-processors, migrates active workloads to them, and only then proceeds with the hot-swap operation, ensuring system stability throughout the maintenance process
Solution Approach 2:
The management controller acts as an intermediary between the host processor and co-processors during hot-swap operations. It coordinates workload migration, manages the removal and insertion of co-processors, and ensures proper system state transitions, thereby maintaining system reliability during maintenance operations
2Ease of repair
If technicians physically manage and maintain co-processors, then hardware issues can be addressed, but the need for physical presence increases operational complexity and response time
Solution Approach 1:
The management controller enables self-service capabilities by automatically managing workload migration and coordinating hot-swap operations without requiring technician intervention. The system can identify failed co-processors, migrate workloads, and facilitate replacement autonomously, reducing both physical presence requirements and operational complexity
Solution Approach 2:
The patent replaces manual mechanical operations with automated electronic control. The management controller uses electronic signals to manage workload migration and coordinate hot-swap operations, substituting the need for physical technician manipulation of hardware components with automated electronic management
3Reliability
If workloads are migrated between co-processors, then system availability is maintained, but the migration process adds complexity to workload management
Solution Approach 1:
The management controller provides universal functionality by handling multiple tasks: identifying failed co-processors, selecting target co-processors for workload migration, coordinating the actual migration process, and managing hot-swap operations. This multi-functional approach consolidates complexity into a single controller rather than distributing it across multiple components

AI summary
An information handling system includes a host processing complex and a wireless management system. The host processing complex instantiates a hosted processing environment and includes a first general-purpose processing unit (GPU) and a GPU hot-plug module that enables a hot-plug operation to replace the first GPU with a second GPU while power is provided to the host processing complex. The hosted processing environment instantiates a first workload on the first GPU. The wireless management system operates out of band from the hosted processing environment, directs the hosted processing environment to halt the first workload, and directs the GPU hot-plug module to perform the hot-plug operation.
