  • Controlling and managing plurality of disk drives in disk enclosure having serial port wherein serial to parallel converters are connected to individual disk drives
    Patent number: 7130939
    Abstract: A disk enclosure is provided with a plurality of HDDs, an enclosure manager that outputs control and management information of the disk enclosure, and S/P converters that are provided for the respective HDDs. Each S/P converter converts a control and management command outputted from the HDD in the form of a parallel signal into a serial signal and outputs it to the enclosure manager. Further, each S/P converter converts control and management information outputted from the enclosure manager into a parallel signal. With this configuration, merely providing a serial port in the enclosure manager and connecting the S/P converters to the enclosure manager by a serial bus can make the SES function of the ESI scheme effective for the HDDs.
