TOR Switch Access Control for Rapid Colocation Rack Provisioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data centers face challenges in deploying IT infrastructure quickly, with provisioning times often taking three to six months, and difficulty in accurately forecasting bandwidth and IT capacity requirements, leading to over-provisioning.
Innovation Solution
A method involving a switch configuration manager that automates the deployment of network switches and virtual networks in data centers, allowing customers to request and configure TOR switches through a portal, enabling rapid deployment of IT infrastructure and network connections.

Engineering Contradiction Analysis
1Productivity
If manual provisioning methods are used for deploying IT infrastructure, then deployment can be performed with simple tools, but provisioning time takes three to six months
Solution Approach 1:
The system enables automated self-service provisioning where the infrastructure automatically configures itself without manual intervention. The provisioning system automatically discovers hardware, configures software components, and deploys services based on customer requests, eliminating the need for manual three-to-six-month provisioning processes while reducing complexity through automation.
Solution Approach 2:
The system performs preliminary actions by pre-configuring and staging infrastructure components before actual deployment. Hardware is pre-discovered, software images are pre-prepared, and configuration templates are pre-established, allowing rapid provisioning when customers place orders, thus accelerating deployment from months to hours without overwhelming system complexity.
2Reliability
If over-provisioning is used to ensure adequate capacity, then service reliability is improved, but resource waste increases
Solution Approach 1:
The system implements dynamic provisioning that automatically adjusts resource allocation based on actual demand and usage patterns. Instead of static over-provisioning, the system continuously monitors performance metrics and scales resources up or down as needed, ensuring service reliability is maintained while eliminating waste from fixed over-provisioned capacity.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor resource utilization, performance metrics, and service quality in real-time. This feedback drives automated decisions about resource allocation, allowing the system to maintain reliable service levels by dynamically adjusting capacity based on actual needs rather than relying on conservative over-provisioning estimates.
3Loss of time
If automated provisioning systems are implemented, then deployment time is reduced to less than 48 hours, but system complexity increases
Solution Approach 1:
The automated provisioning system is segmented into distinct modular components: hardware discovery module, software configuration module, service deployment module, and validation module. Each component handles specific tasks independently, which manages overall system complexity while enabling parallel processing that achieves sub-48-hour provisioning times through coordinated automation.
Solution Approach 2:
The system introduces an intermediary provisioning platform that sits between customer requests and underlying infrastructure complexity. This intermediary automatically translates high-level customer requirements into detailed configuration instructions, managing the complexity transition and enabling rapid deployment without exposing customers to system complexity while achieving deployment in less than 48 hours.
Data Source
AI summary
Top-of-rack (TOR) switches are connected to a network fabric of a data center. Each TOR switch corresponds to a rack of the data center, and is configured to provide access to the network fabric for computing devices mounted in the rack. In one method, a TOR switch is mounted in a rack. The TOR switch is connected to a network fabric of a data center. A lock is used to control physical access to the rack. A request to physically access the rack is received from a computing device (e.g., a badge implementing a security token, or a mobile device). The request includes authentication credentials. The computing device is then authenticated. In response to authenticating the computing device, the lock is configured to provide physical access to the rack.
