SDDC Manager Network Fabric Migration Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual server rack systems face disruptions and inefficiencies during network fabric migrations between Layer 2 (L2) and Layer 3 (L3) due to the lack of a centralized entity managing diverse hardware and software components with different operating systems, leading to potential outages and resource reconfiguration requirements.
Innovation Solution
The implementation of a System Defined Data Center (SDDC) manager that detects, migrates, and validates network fabric changes without disrupting existing workloads by using a fabric migrator to switch between L2 and L3 networks, ensuring seamless transitions and system-level governance across heterogeneous components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network fabric migration is performed in virtualized server systems without centralized management, then hardware and software components can operate independently, but system reliability deteriorates due to disruptions and outages during migration
Solution Approach 1:
The SDDC manager acts as an intermediary between the network fabric components and the virtualized server systems. During network fabric migration, the SDDC manager detects the migration, validates the new fabric configuration, and coordinates the transition to ensure system reliability while managing the complexity of heterogeneous components with different operating systems
2Reliability
If network fabric migration is performed without validation, then migration speed increases, but system reliability deteriorates due to potential outages
Solution Approach 1:
The SDDC manager performs preliminary validation of the new network fabric configuration before completing the migration. This includes detecting the new fabric, verifying its operational status, and ensuring compatibility with existing workloads. This preliminary action prevents outages while minimizing migration time by identifying and resolving issues before they cause disruptions
3Reliability
If centralized management is implemented to manage network fabric migration, then system reliability improves through coordinated transitions, but device complexity increases due to additional management layer
Solution Approach 1:
The SDDC manager is designed as a universal management platform that handles multiple functions including network fabric detection, validation, and migration coordination across heterogeneous hardware and software components. By consolidating these diverse management tasks into a single multi-functional system, the patent reduces overall system complexity while improving migration reliability

AI summary
Methods, apparatus, systems, and articles of manufacture to perform network fabric migration in virtualized servers are disclosed and described. An example apparatus a layer detector to determine a first network fabric layer of a communication network by sending a first probe packet from a first network resource to a second network resource via a communication link and determine to migrate the first network fabric layer to a second network fabric layer based on whether the first network resource receives a reply probe packet from the second network resource in response to the first probe packet. The example apparatus further includes a layer migrator to when the first network resource receives the reply probe packet from the second network resource in response to the first probe packet, migrate the first network fabric layer to a second network fabric layer based on configuring a remediation path and migrate the remediation path from the first network fabric layer to the second network fabric layer when the first network fabric layer migrates to the second network fabric layer.
