Abstract: A storage system includes a storage server and a storage subsystem having an I/O module coupled to disks. The storage server includes a storage adapter coupled to the I/O module creating an in-band (data) path to access data stored on the disks. The storage server sends a data command through the in-band path to the I/O module for accessing the data stored on the disks. The storage server further includes a network adapter coupled to the I/O module creating an out-of-band control path to control the I/O module. The storage server detects through the in-band path that the I/O module is non-responsive to a data command and automatically changes the behavior of the I/O module (e.g., resets the I/O module) through the out-of-band control path to recover the non-responsive I/O module. The storage server also collects and outputs status data of the I/O module through the out-of-band control path.

Abstract: Methods and apparatuses for dynamically budgeting power usage in a data processing system. In one aspect, a data processing system, includes: one or more components including a first component; and a computing element, such as a microprocessor or a microcontroller, coupled to the first component to obtain one or more operating signals from the first component and to determine, based at least in part on the one or more operating signals, an estimate of a power consumption requirement of the one or more components for operating under the current condition. In one example, one or more sensors are used to determine information on actual power usage for a past period of time. A performance level setting of a second component, such as a CPU, a GPU, or a bus, is determined using the estimate and the information on the actual power usage, such as the operating voltage and frequency.

Abstract: A method of performing a network management transaction between a network device, having a network management agent installed thereon, and a remote device, having a web-browser installed thereon, is described. The method involves firstly performing a network management function relating to the network device. Data concerning the network management function is then propagated from the agent to the remote device in a format capable of display by the browser. More specifically, a document is propagated from the agent to the remote device for display by the browser, the document incorporating the data concerning the network management function. The document may be an HTML document. Alternatively, the data may be propagated in a format for display by the browser under the direction of an application program resident of the remote device.
