A hierarchical, distributed Availability Management (AM) process for recovering from component failures in a data processing system. The hierarchy of AM elements track a failure modality hierarchy of the data processing system components. For example, the system hierarchy may include system cards, processors, and processes, in which case the associated AM elements may be implemented at a card manager (CM) level, a system manager (SM) level, and a process manager (PM) level. The AM hierarchy is designed to achieve a failure granularity so that failures in the lower levels of the hierarchy have less of an impact on the entire system. Each AM element is responsible for receiving failure notifications from processing system components associated with a next lower level of the hierarchy. Upon such indication, if the AM element determines that the failed component may be restarted, if the failed component may be restarted, the AM element then determines if it can be hot, warm, or cold restarted and it does so without further notification or implication to system availability of other components. Hot restart requires complete integrity of sate information, warm restart causes a recovery of last known good state information, and a cold restart results in the re-initialization of state information. If, the component cannot be restarted, then notification is provided to the next higher level of the hierarchy and the AM element itself terminates. One of the AM processes may execute as an identity management protocol. The identity protocol sets a temporary master state; waits a predetermined amount of time; and then sets a final master state only if no other system card has asserted a temporary master state. The waiting time period is selected to be greater than the longest expected initialization process for peer components in the system.

Server cluster management includes dynamically migrating machines between different server pools within the server cluster. The server pools include an active pool and at least one standby pool. Different standby pools can also be maintained to provide machines in different states of standby, including but not limited to different powered down or hibernation states. Machines are migrated between the different server pools based on network demands and machine status and capabilities. In some instances, the network demands are determined by forecasting future demands. The status and capability of the individual machines is evaluated on a continual basis to determine whether there is adequate capacity of the machines in the active pool to satisfy the one or more network demands, as well as to determine which machine is the most appropriate machine to migrate between server pools. Machines can also be migrated between the different standby pools.

A service framework uses importance ranking information in making call decisions and / or wait-time decisions in connection with service requests. Each of the service requests has an importance ranking which reflects the importance of the information provided by the service to a task being performed. The health of a service may be controlled by permitting fewer (or more) service requests to be made to the service when the service is less (or more) healthy. The likelihood of a service request being made to the service may depend on the importance ranking of the service request. When waiting for a response, a determination whether to continue waiting may be made based on the likelihood that the service has failed and based on the importance of the information to the task being performed.

A distributed control protocol dynamically establishes high availability (HA) partner relationships for nodes in a cluster. A HA partner relationship may be established by copying (mirroring) information maintained in a non-volatile random access memory (NVRAM) of a node over a HA interconnect to the NVRAM of a partner node in the cluster. The distributed control protocol leverages a Cluster Liveliness and Availability Manager (CLAM) utility of a storage operating system executing on the nodes to rebalance NVRAM mirroring and alter HA partner relationships of the nodes in the cluster. The CLAM utility is configured to maintain various cluster related issues, such as CLAM quorum events, addition or subtraction of a node in the cluster and other changes in configuration of the cluster. Notably, the CLAM utility is an event based manager that implements the control protocol to keep the nodes informed of any cluster changes through event generation and propagation.
