services to LAN attached clients. Features MC/ServiceGuard monitors the health of various components within each node and quickly responds to failures in a way that eliminates or minimizes application downtime. MC/ServiceGuard is able to detect and respond to failures in: • SPU • System memory • System and application processes • LAN media and adapters • Storage sub-system and adapters For ease of management and outstanding flexibility MC/ServiceGuard for Linux allows all of the resources needed by an application to be organized into entities called "application packages". Application packages consist of any resource needed to support a specific application service such as disks, network resources, and application or system processes. Packages are the entities that are managed and moved within the enterprise cluster. MC/ServiceGuard for Linux is an important component in creating a complete and robust environment for highly available mission critical applications. In order to create a complete solution, the application environment should be designed to eliminate all single points of failure and to minimize the impact of various component failures. System Software The memory requirement for MC/ServiceGuard for Linux depends on the number of packages configured in the cluster. The following equation provides a rough estimate of how much lockable memory is needed: Total Memory = 6 MB + 80KB/package in cluster The total amount is needed on all nodes in the cluster, regardless of whether a given package or resource is on that node or not.
