摘要:
A system for pre-execution environment (PXE) booting a storage processor from a peer storage processor allows for the ability to reboot and/or restart the storage processor without an externally connected PXE server. In response to a reboot request of the storage processor, the peer storage processor pushes an operating system boot image and/or other information to the storage processor for PXE booting the storage processor, and vice versa. The system may also operate with multiple coupled computers.
摘要:
A system that provides efficient expansion capability of a storage unit under test including multiple storage processors and reduces a number of required Ethernet ports on a client device and a reduced number of physical connections on the client device. A first processor and a peer processor of a storage processor system may be coupled to counterpart processors on one or more other storage processor systems using direct port-to-port connections and/or using a network infrastructure. A command from the client device may be passed among first processors and peer processors of the multiple storage processor systems until the correct destination processor for the command is reached, and data packets may be passed from a source processor of a storage processor system through processors of other storage processor systems until the client device is reached.

摘要:
A method for automatically diagnosing faults a data storage system. The system includes a plurality of enclosures each having: a primary port; an expansion port; a plurality of disk drives; and a link control card coupled to the primary port and to the expansion port and the plurality of disk drives. The link control card includes a cut through switch having: disk drive port error counters for counting at ports of the plurality of disk drives; a primary port error counter for counting cumulative errors at the primary port, and an expansion port error counter for counting cumulative errors at the expansion port. The primary ports and expansion ports are serially interconnected to the storage processor through a fiber channel loop. The method sequentially reads counters in each one of the enclosures to determine whether errors counted in any one of such counters exceeds a predetermined threshold over a predetermined period of time.
摘要:
A method for detecting faulty operation of a multi-variable system is described. The method includes receiving operational data from a plurality of components of the multi-variable system and processing the operational data in accordance with a plurality of dynamic machine learning fault detection models to generate a plurality of fault detection results. Each fault detection model uses a plurality of variables to model one or more components of the multi-variable system and is adapted to detect normal or faulty operation of an associated component or set of components of the multi-variable system. The plurality of fault detection results are output.
