摘要： The present invention relates to a power saving apparatus for a hard disk drive in a battery powered computer and to a method of controlling the same in the battery powered computer. CPU of the power saving apparatus is configured to generate a request signal for receiving battery level data from a power control unit, to enable a disk cache to operate in a write back mode if the battery level is available for a predetermined time period, and to control the power control unit to produce a switch off signal after writing all data contained in the cache into the hard disk is completed in response to a power off system management interrupt signal from the power control unit. With this configuration, access to the hard disk drive is restricted and power consumption of hard disk drive is reduced without the loss of data in the cache when there is a sudden system power off.

摘要： Transceivers are selectively activated to reduce power in a network of data processing devices linked by a data transmission loop. Each of the devices is linked by a transceiver, and passes data from a previous device in the loop to a next device in the loop when not transmitting data onto the loop. For example, the data processing devices are disk drives in a storage subsystem. Delays in establishing communication after transceiver activation can be avoided by continuously powering a bit clock oscillator or bit synchronizer. In one embodiment, a loop controller in the loop sends activation and deactivation signals to addressed transceivers via an auxiliary channel. In another embodiment, when a device detects that communication is occurring between other devices for a certain period of time, the device selectively deactivates its transceiver for the certain period of time. For redundancy, the data processing devices can be connected via dual loops, and then power is further reduced by activating at most one of the two transceivers in a device at any given time. In this case, if a transceiver failure occurs, the failed transceiver is bypassed and the other transceiver for the device is activated. For example, when a loop controller detects a transceiver failure, the loop controller sends transceiver activation and deactivation signals over the auxiliary channel.

摘要： A peripheral equipment control LSI interposed between an SCSI bus connected to a main CPU and peripheral equipment such as a file device. The LSI is divided into two major blocks. One block recognizes an SCSI protocol ID signal sent over the SCSI bus. The other block generates a signal that causes the other block to leave a sleep state (low power dissipation mode). In a state in which a command is awaited from the main CPU, the peripheral equipment control LSI allows the block containing the ID recognition part to remain active while the other block is kept in the sleep state. On receiving an ID-based selected (access) signal from the main CPU, the LSI detects the start of an access operation and causes the other block to leave its sleep state and to become active.

摘要： A method and system of operating a power-managed computer system monitors the life cycle of a hard disk drive attached to the computer system and extends the life span of the hard disk drive by reducing the rate at which hard disk drive spin-up cycles are initiated when the hard drive reaches a predetermined stage it life cycle. Software routines which activate or spin-up the hard drive are extended in capability to read the hard drive serial number and record the serial number in a non-volatile memory in conjunction with an incrementing counter. The incrementing counter counts the number of times the hard drive has been activated from the time of installation of the hard drive. The count of spin-up occurrences is indicative of the operating age of the disk drive. A plurality of age levels are defined, for example medium, old and ancient levels so that, when the hard drive spin-up count reaches one of the defined levels, the power management system changes the operation of the hard drive power management.

摘要： An apparatus is programmed with a plurality of programming instructions for generating, if possible, an alternative disk block allocation for a current disk block allocation that will yield reduced overall power consumption for a sequence of disk accesses. In some embodiments, the programming instructions include the logic for tracing the sequence of disk accesses to determine the current disk block allocation, the logic for generating the alternative disk block allocation, if possible, using the trace results, and the logic for effectuating the alternate disk block allocation, if generated. In one particular embodiment, the logic for generating the alternative disk block allocation employs a random search approach, while in another embodiment, the logic for generating the alternative disk block allocation employs a heuristic approach.

摘要： A system and method for optimizing power consumption by a disk drive unit. The system and method monitor and analyze historical use data and calculate a predicted inactivity duration. The predicted inactivity duration is used to power-down the rotational speed of the drive to the first of one or more intermediate rotational speeds. Continued inactivity will result in further speed reduction until the drive is ultimately powered off. The drive increases rotational speed on demand.

摘要： A disk drive power manager that compares energy usage with a predetermined profile to select one of several reduced-power operating modes. An energy usage register is updated at regular intervals according to the energy used during each time interval. An attenuated average energy usage value is obtained by attenuating the energy usage measures over time and integrating the results. The average energy level is compared with several predetermined energy threshold profiles to select a full- or reduced-power operating mode. Operating mode selection automatically adapts to the usage pattern to optimally balance power consumption with operational accessibility.

摘要： A data storage and retrieval system is provided which has extremely high capacity. The system includes a large array of small disk files, and three storage managers for controlling the allocation of data to the array, access to data, and the power status of disk files within the array. The allocation manager chooses the disk files upon which incoming data is written based on the current state of the disk files (active or inactive), the available capacity, and the type of protection desired (i.e unprotected, RAID), mirrored, etc.). The access manager interprets incoming read requests to determine the location of the stored data. The power manager sequences disk files between active and inactive to provide the storage requested by the access and allocation managers. The power manager also maintains the disk array in conformance with thermal and power constraints to avoid excessive power consumption or thermal overload while keeping active the optimal subset of the disk array based on the storage requests pending at any point in time.
