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.
Software Required
One MC/ServiceGuard for Linux license must be ordered for each system (node).
