Common use of FUNCTIONAL DESCRIPTION Clause in Contracts

FUNCTIONAL DESCRIPTION. The High Availability Module implements a redundant configuration for Customer, designed with the goal of having no single point of failure in the System. High Availability is accomplished in the System at the database tier through clustering, with multiple database nodes serving the application server tier. The cluster uses a common network-attached storage so that all System database nodes are referencing the same data set. The network-attached storage is itself redundant, with multiple controllers and multiple network connections to the database nodes. In the System’s application tier, there are redundant application servers running in a load-balanced configuration.
