Method and apparatus for preserving data in a high-availability system preserving device characteristic data

Method and apparatus for preserving data in a high-availability system preserving device characteristic data

In a system comprising a plurality of components, characteristic data is stored on programmable read-only-memories (PROMS) on each component. The PROMs are coupled together via a simple bus, and data is retrieved from the PROMs using the bus. The collection of data from the PROMs provides the compon...

description In a system comprising a plurality of components, characteristic data is stored on programmable read-only-memories (PROMS) on each component. The PROMs are coupled together via a simple bus, and data is retrieved from the PROMs using the bus. The collection of data from the PROMs provides the component characteristic data, and a portion of the component characteristic data is stored in one or more persistent media devices in the system, creating a last known good copy. The persistent storage device could be any device that does not lose data in the event of a loss of power.
