Telecommunications Carrier: Massively Scalable Server Farm Implementation

Business Need: Create a platform for the client’s next-generation services, optimized for ease of maintenance and maximum, enterprise-wide availability.

Solution: The client required an integrated z/VM and Linux architecture that would provide an appropriate platform for deploying Web Services applications for both internal use and external customers. The design involved a pair of z/VM 4.3 systems with mass storage (DASD) shared between them. Virtual IP addressing played a major role in the design to provide transparent adapter-to-adapter failover, ensuring high availability to a particular physical machine, and to provide routing to each guest’s virtual IP address so that it could be located from the network while running on any frame. Sine Nomine Associates developed the initial design in collaboration with the client team and other partners. Over the course of the project, Sine Nomine Associates directed implementation efforts by the overall team.
