  • Systems and methods for heat extraction in a power supply
    Patent number: 8830680
    Abstract: Power supply and heat sink modules are suitable for use in sealed outdoor enclosures. Circuit elements in the power supply modules are connected to multiple heat sinks. The heat sinks are combined in heat sink modules. The heat sink modules provide high thermal conductivity while avoiding electromagnetic interference.

  • Environment monitoring system for standard interface bus computer systems
    Patent number: 5337413
    Abstract: An apparatus and method for monitoring the environment of remote components attached to a host processor by means of a standard interface bus having a limited number of address ports. The invention includes a host adapter incorporating a standard bus repeater component and an environment monitoring component. The environment monitoring component has a standard bus interface and is selectably coupled to the standard interface bus, and hence to a host processor. The host interface transceiver is coupled by means of a standard bus to the host processor, and is also selectably coupled to a drive interface transceiver by means of the standard bus. The drive interface transceiver is coupled by the standard bus to one or more storage devices. The host adapter is selectably switchable between two modes, such that either the drive interface transceiver is coupled through the host interface transceiver to the host processor, or the environment monitoring component is coupled to the host processor.

  • Storage device array architecture with copyback cache
    Patent number: 5274799
    Abstract: A fault-tolerant storage device array using a copyback cache storage unit for temporary storage. When a Write occurs to the RAID system, the data is immediately written to the first available location in the copyback cache storage unit. Upon completion of the Write to the copyback cache storage unit, the host CPU is immediately informed that the Write was successful. Thereafter, further storage unit accesses by the CPU can continue without waiting for an error-correction block update for the data just written. In a first embodiment of the invention, during idle time for relevant storage units of the storage system, an error-correction block is computed for each "pending" data block on the copyback cache storage unit, and the data block and corresponding error-correction block are copied to their proper location in the RAID system.
