Abstract
A computing environment includes a number of nodes, one of which is a primary node that controls the operation of the computing environment and another of which is a backup node that is capable of controlling operation of the computing environment. The primary node includes a hardware management module (HMM) that controls hardware components in the computing environment. The HMM also detects and reports events relating to the hardware components. The primary node further includes a software management module (SMM) that controls instances of software components of the computing environment, and detects and reports events related to the same. A node management module (NMM) in the primary node elects the node as the primary from among the number of nodes. The NMM receives the reports of events from the HMM and SMM, and selectively transfers operational control of the computing environment to a backup node in response to the reports. A configuration management module (CMM) transfers a configuration of the computing environment to the backup node. A replication library is used in transferring a state of each of the instances of software components to the backup node.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
