The Open University currently delivers fourteen courses via the Internet at the moment but many more will follow.
Problem
The University were looking for a technology partner that could provide Content Switching and Server Load Balancing to specific parts of their web farm.
The specific requirements were to provide:
- A High Availability solution that could be integrated into their Gigabit Ethernet infrastructure and provide URL and cookie based Content Switching between multiple pairs of redundant content servers.
- A high throughput solution that could deal with a demanding daily amount of web traffic. To deliver the required solution and to meet a predefined deadline.
Technical Details
The Open University has successfully integrated the High Availability pair in to their production environment, and are beginning to benefit from the NetScaler's powerful flexible content switching and load balancing capabilities.
Solution
During the initial IT planning and consulting phase, HTL analysed The Open University's requirements carefully and created an IT solution based on the integration of NetScaler traffic management technology into the universities existing web infrastructure, the project consisted of the following elements:
- A 6-week evaluation utilising a NetScaler 9400 T Request Switch and the Universities in-house pre-production environment, to test functionality and define final deployment criteria.
- Specification of final hardware and software solution of NetScaler 9800 HA-T request switches and confirm project readiness.
- Pre-configuration and testing in HTL labs.
- Delivery and on-site commissioning of final solution with the Universities Web team.
- Provision of a 12 x 5 Silver technical support package with advanced hardware swap out for the chosen solution.
Conclusion
The solution was installed on time and to budget, and has fulfilled all of its requirements.
Since installation, The Open University has successfully integrated the High Availability pair in to their production environment, and are beginning to benefit from the NetScaler's powerful flexible content switching and load balancing capabilities.
