Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for maintaining and upgrading virtual server racks in cloud computing environments are costly and labor-intensive, requiring manual effort and spare resources, leading to potential downtime and security breaches during maintenance tasks.
Innovation Solution
The implementation of a nested rack manager (NRM) that dynamically allocates and manages resources across existing physical racks, enabling the creation of virtual nested racks for workload expansion and maintenance without the need for additional physical resources, thereby reducing downtime and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual maintenance and upgrading methods are used for virtual server racks, then security and control are improved, but labor intensity and costs increase
Solution Approach 1:
The system implements automated self-service through the nested rack manager that autonomously performs workload migration, resource allocation, and rack decommissioning without manual intervention. The NRM continuously monitors resource availability and automatically executes maintenance tasks, eliminating the need for manual operations while maintaining security through controlled automated processes.
2Loss of time
If spare resources are allocated for maintenance operations, then downtime is reduced, but resource utilization efficiency decreases
Solution Approach 1:
The patent implements nested virtual racks within existing physical racks, creating a hierarchical structure where virtual racks can be dynamically created, migrated, and decommissioned without requiring separate spare physical infrastructure. The nested architecture allows workloads to be moved between nested racks during maintenance, eliminating downtime while using existing resources efficiently rather than allocating dedicated spare resources.
Solution Approach 2:
The system dynamically allocates and migrates workloads between nested racks based on real-time resource availability and maintenance requirements. The nested rack manager continuously adjusts resource allocation, creating and destroying nested racks as needed, which reduces downtime for maintenance operations while maintaining high resource utilization by avoiding static spare resource allocation.
3Adaptability or versatility
If additional physical racks are deployed for workload expansion, then scalability is improved, but cost and floor space consumption increase
Solution Approach 1:
The patent creates virtual nested racks within existing physical rack infrastructure, enabling workload expansion and scalability without deploying additional physical racks. The nested architecture allows multiple virtual racks to coexist and be managed within a single physical rack, providing scalable capacity while minimizing physical resource consumption and floor space requirements.
Solution Approach 2:
The system transitions from horizontal physical rack expansion to vertical virtualization within existing racks. By creating nested virtual racks within the existing physical infrastructure, the system achieves scalability in the virtual dimension rather than requiring additional physical dimensions, thereby expanding capacity without increasing physical resource quantity or floor space consumption.
4Measurement precision
If manual resource allocation is performed during maintenance, then control precision is improved, but time consumption and productivity decrease
Solution Approach 1:
The nested rack manager implements continuous feedback mechanisms that monitor resource availability, workload status, and maintenance progress in real-time. This feedback enables the system to automatically adjust resource allocation with high precision while maintaining fast maintenance speeds, as the automated system can process and respond to status changes much faster than manual operations without sacrificing control precision.
Solution Approach 2:
The patent replaces manual mechanical resource allocation processes with automated software-based management. The nested rack manager uses automated algorithms and software controls to allocate and migrate workloads during maintenance, substituting human manual operations with automated systems that achieve both high control precision and fast maintenance execution speeds.

AI summary
Methods, apparatus, systems, and articles of manufacture are disclosed for rack nesting in virtualized server systems. An example apparatus includes a resource discoverer to identify resources to be allocated to the nested rack based on a policy indicative of one or more physical racks from which to identify the resources, and determine candidate resources from the resources to be allocated to the nested rack based on a capacity parameter indicative of a quantity of the resources available to be allocated to the nested rack, the candidate resources to have first hypervisors, and a nested rack controller to generate the nested rack by deploying second hypervisors on the first hypervisors, the second hypervisors to facilitate communication between the candidate resources and one or more virtual machines on the second hypervisors, the nested rack to execute one or more computing tasks based on the communication.
