Hardware Resource Reservation for SDDC Management Appliances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing software-defined data centers (SDDCs) across multiple geographical regions and hybrid deployments is challenging due to the complexity of monitoring compliance and upgrading VIM server appliances, as existing solutions lack efficient hardware resource management.
Innovation Solution
Implementing a cloud control plane that centrally manages SDDCs through agents in a cloud gateway appliance, ensuring sufficient hardware resources by reserving and allocating processor and memory resources for management appliances, and maintaining a desired state for the shared cluster using JSON files to remediate any drift.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If management appliances are deployed on shared cluster hosts without dedicated resource reservation, then hardware resource utilization is improved, but management operations reliability deteriorates due to insufficient hardware resources
Solution Approach 1:
The patent segments hardware resources into dedicated management resource pools and workload resource pools. By creating separate resource pools for management appliances, the system ensures that management operations have guaranteed hardware resources while still allowing workloads to utilize remaining capacity, thus resolving the contradiction between resource utilization and operational reliability.
Solution Approach 2:
The patent implements preliminary resource reservation for management appliances before deploying workloads. By pre-allocating CPU, memory, and storage resources to management resource pools, the system ensures that management operations will always have sufficient resources available, preventing reliability issues while maintaining efficient overall resource utilization.
2Reliability
If hardware resources are reserved for management appliances, then management operations reliability is improved, but hardware resource utilization deteriorates due to dedicated resource allocation
Solution Approach 1:
The patent implements dynamic resource allocation within reserved management resource pools. The system allows management appliances to utilize up to their reserved resource limits while permitting workload access to any unused capacity within those pools. This dynamic sharing mechanism maintains reliability through reservations while maximizing utilization by allowing flexible resource sharing when management resources are not fully consumed.
3Adaptability or versatility
If VIM server appliances are managed across multiple geographical regions without centralized management, then deployment flexibility is improved, but compliance monitoring complexity deteriorates
Solution Approach 1:
The patent implements a centralized management system that provides universal compliance monitoring capabilities across multiple geographical regions and hybrid cloud environments. The system can monitor and manage VIM server appliances regardless of their deployment location (on-premise, public cloud, or service), providing a unified approach to compliance monitoring that reduces complexity while maintaining deployment flexibility.
Solution Approach 2:
The patent introduces a centralized management intermediary that acts as a mediator between distributed VIM server appliances and compliance requirements. This intermediary consolidates compliance monitoring functions, providing a single point of control that simplifies the monitoring of appliances across multiple geographical regions while preserving the flexibility of distributed deployments.
4Difficulty of detecting and measuring
If cloud gateway appliance agents are deployed for centralized cloud services, then compliance monitoring capability is improved, but system complexity deteriorates due to additional infrastructure components
Solution Approach 1:
The patent implements self-service agents in the cloud gateway appliance that automatically perform compliance monitoring and reporting functions. These agents autonomously collect data from VIM server appliances, assess compliance status, and generate reports without requiring manual intervention. This self-service approach enhances compliance monitoring capability while minimizing the operational complexity of managing the additional infrastructure.

AI summary
A method of reserving hardware resources for management appliances of a software-defined data center (SDDC) that have been deployed onto one or more hosts of a cluster of hosts, includes reserving hardware resources of the cluster for a resource pool that has been created for the management appliances, the hardware resources including at least processor resources of the hosts and memory resources of the hosts, and assigning the management appliances to the resource pool created for the management appliances. The management appliances share the hardware resources of the cluster with one or more other resource pools and, after the steps of reserving and assigning, are allocated at least the hardware resources that have been reserved for the resource pool created for the management appliances.
