Title:
DATA TRANSFER SYSTEM AND SYSTEM HOST
Document Type and Number:
WIPO Patent Application WO/2021/075154
Kind Code:
A1
Abstract:
Provided is a system host with which, even when the state of insertion/removal of a local device into/from an adapter changes in a data transfer system while the system host is in an idle state, it is possible to properly transmit/receive data to/from the local device and the adapter after restoration from the idle state. The adapter has a local device inserted therein and can connect to the local device, the adapter being provided with a switch unit that performs a data transfer between the local device and the system host by address translation and requester (Req) ID conversion. When the local device is inserted or removed while in operation, the system host confirms the type of protocol of the local device and reloads a device driver on the basis of the confirmation, the device driver furthermore being provided with a pre-idle state storage unit for storing the insertion/removal state of the local device immediately before the system host and the adapter enter an idle state.
