摘要： A peripheral device reliably reports errors to a main device. When a control signal is received from the main device, an interface circuit requests a voltage detecting circuit to determine whether or not a main circuit section is operative. The voltage detecting circuit determines the capability of operation of the main circuit section based on the state of charge of a charging/discharging section, and outputs the results to the interface circuit. If determined to be operative, the interface circuit turns on a power supply switch to operate the main circuit section, while outputting the control signal received from the main device to the main circuit section. If inoperative, the interface circuit transmits to the main device a signal informing it of the inoperative state.

摘要： A hierarchic disk array data storage system (10) has multiple storage disks (12) that define a physical storage space (34) and a RAID management system (16) that maps the physical storage space (34) into two virtual storage spaces. A RAID-level virtual storage space (40) presents the physical storage space as mirror and parity RAID areas where the mirror RAID areas store data according to RAID Level 1 and the parity RAID areas store data according to RAID Level 5. An application-level virtual storage space (50) presents the physical storage space as multiple virtual blocks. The RAID management system (16) migrates data between the mirror and parity RAID areas to optimize performance and reliability. To facilitate migration, the RAID management system (16) guarantees a minimum of unused storage space that can be used to empty a RAID area for the purpose of converting the RAID level or other storage attribute of the RAID area. The minimum unused storage space is preferably equivalent in size to at least one largest parity RAID area. However, the unused storage space is not in any one physical location, but can be allowed to distribute itself over various RAID areas in a non-contiguous manner across the storage disks.

摘要： A computer system comprises a host processor, host memory, and a mass storage device interconnected via a high-speed data bus. An operating system and a driver for the mass storage device are implemented on the host processor. The mass storage device is capable of being connected to the computer system via the data bus, such that a portion of the host memory is allocated for use by the mass storage device; the mass storage device uses the host memory portion for one or more particular mass storage device operations; and the operating system and the driver are unaware of how the mass storage device uses the host memory portion. In a preferred embodiment, the mass storage device requests and the host processor allocates a portion of host memory for exclusive use by the mass storage device to perform such functions as predictive failure analysis, maintenance of deallocated sector lists, and data prefetching.

摘要： The invention relates to a process of storing data on, or retrieving data from, a plurality of disks (15). In one embodiment the process uses up to four commercial disks (15) in parallel to increase bandwidth and capacity. To store data onto the disks (15), the data in the main memory is divided into segments numbered modulo 4, and each disk (15) then accesses and stores the same numbered segments. There is no master disk, and each disk (15) stores data asynchronously at its own speed. The system is transparent to the user in that it appears to be one disk. For retrieval from the disks (15), each disk (15) supplies its segments, which are then assembled in memory.
