控制器的連接數(shù)量有限，這終可能會導致
導致控制器無法建立連接。If the Cache Connections option is selected, the controller keeps the connection open after it completes the data transfer. The next data transfer uses the open connection and avoids the delay required to open the connection. If this option is not selected, the controller closes the connection after the data transfer operation is complete. Selecting the option results in faster data transfers, but indefinitely retains a connection. Since the controller has a limited number of connections, this could eventually result in the controller being unable to establish connections.
