Techniques for system recovery using a failover processor are disclosed. A first processor, with a first instruction set, is configured to execute operations of a first type; and a second processor, with a second instruction set different from the first instruction set, is configured to execute operations of a second type. A determination is made that the second processor has failed to execute at least one operation of the second type within a particular period of time. Responsive to determining that the second processor has failed to execute at least one operation of the second type within the particular period of time, the first processor is configured to execute both the operations of the first type and the operations of the second type.

System recovery using a failover processor

Some embodiments of the present invention provide virtual configuration systems and methods that overcome some or all of the downfalls of typical approaches by allowing for persistent configuration of an operating system of a host device. A virtual configuration layer may be incorporated into the file system of the host device and executed to modify configuration data stored outside of the file system, without changing the file system. Once the configuration data is modified, it may be used to configure the file system and/or the operating system of the host device when it is loaded by a client device. In some embodiments, the host device may be nonvolatile storage (e.g., a flash drive) embedded into a client device (e.g., a diskless system).

Virtual configuration systems and methods

Techniques for error handling by a servomechanism are disclosed. The servomechanism determines, based on a first set of values assigned to servomechanism variables, electrical signals for controlling a component during a particular time interval, and applies the electrical signals to move the component. Subsequently, the servomechanism measures values for attributes associated with the component. Based on the measured attribute values, the servomechanism computes a second set of values for the servomechanism variables. Responsive to determining that the measured attribute values are erroneous, the servomechanism refrains from modifying the electrical signals based on the second set of values for the servomechanism variables.
