Loop network system and data storage devices included therein

摘要

Embodiments of the present invention provide a loop network system and data storage devices connected thereto where the data storage devices (nodes) can perform effective pieces of processing and the probability of error occurrence can be reduced. One embodiment according to the present invention includes a Fibre Channel Arbitrated Loop network, a Host controller and multiple HDDs connected thereto. A port on the network outputs parameters to control loop initialization processing as well as a LIP Order Set. Each port performs loop initialization processing according to the received parameters and transfers the received LIP Order Set with parameters appended to the down stream.
