The Sun StorEdge 6130 array is designed to provide high levels of reliability, availability, and serviceability (RAS). All components in the array's data path are redundant so that the data path has no single point of failure. If one component fails, the array switches to the alternate component automatically. The following components have been designed for high-availability:
A configuration that has hot-spares in every storage tray and array hot-spares in every pool supports high availability.
The Sun StorEdge 6130 array uses several mechanisms to recognize a hardware failure. When a component recognizes that it has failed or the management software detects a failure, the component is removed from active service and its functions are assigned to other components of the array. The array generates an error event and records it in log files. Error events and log files are managed by the Sun Storage Automated Diagnostic Environment.
