System of controlling and managing disk storage in a disk enclosure
First Claim
1. A disk enclosure, comprising:
- a disk storage for storing data;
an enclosure manager for outputting control and management information for the disk enclosure in response to a request of a host system; and
a converter for outputting control and management information outputted from the disk storage as a parallel signal to the enclosure manager after serial conversion, and outputting control and management information outputted from the enclosure manager as a serial signal to the disk storage after parallel conversion.

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.
