Latest Patents

Gertwagen holds a patent for a method and apparatus titled "Filesystem failover in a single system image environment." This invention provides a transparent failover of a filesystem within a computer cluster. The system is designed to ensure that a filesystem is physically connected to both an active server node and a standby server node. The cluster file system allows for distributed access to the filesystem throughout the computer cluster. It monitors the progress of operations performed on the failover protected filesystem. In the event of a failure of the active server node, all processes are temporarily halted, and the filesystem is relocated to the standby server node. Once the transition is complete, the system resumes operations by waking each sleeping process and retrying pending operations. Gertwagen's innovative solution enhances the reliability and efficiency of computer systems.
