Managing Transfers

The HST Server GUI enables you to start, stop, and reorder transfers, as well as adjust transfer rates and policies and configure transfer preferences.

The Transfers Panel: Start, Stop, and Reorder Transfers

Once the transfer starts, a progress bar appears in the Transfers panel. You can manage transfer behavior with the following actions:

Click to start the selected transfer.
Click to stop the selected transfer.
Click to delete the selected transfer.
If you have multiple ongoing transfers, use the and to change the selected transfer's priority. The # field indicates the transfer's order in the queue.

Note: The file name is not shown in the Name or Source fields in the Transfer pane if the client is using version older than 3.7.0.

The Details View: Adjust Transfer Rates and Policies of Active Transfers

The Details button provides additional oversight and control (if you have permission) over transfers. Select a transfer session from the Transfers panel and click Details to view details and adjust settings.

The Details display shows the following information:

Item	Name	Description
A	Details (tab)	Transfer details, including status (rate and ETA) and statistics (session size, files transferred vs. total files to be transferred, average speed, time elapsed, RTT delay and average loss in percent).
B	Files (tab)	All files being transferred in this session, along with each files' size and transfer progress.
C	Transfer controls	Set the FASP transfer policy and transfer rate, if allowed. `high` - Adjust the transfer rate to fully utilize the available bandwidth up to the maximum rate. When congestion occurs, the transfer rate is twice as fast as a fair-policy transfer. The `high` policy requires maximum (target) and minimum transfer rates. `fair` - Adjust the transfer rate to fully utilize the available bandwidth up to the maximum rate. When congestion occurs, bandwidth is shared fairly by transferring at an even rate. The `fair` policy requires maximum (target) and minimum transfer rates. `low` - Adjust the transfer rate to use the available bandwidth up to the maximum rate. Similar to fair mode, but less aggressive when sharing bandwidth with other network traffic. When congestion occurs, the transfer rate is reduced to the minimum rate until other traffic decreases. `fixed` - Attempt to transfer at the specified target rate, regardless of network or storage capacity. This can decrease transfer performance and cause problems on the target storage. Aspera discourages using the `fixed` policy except in specific contexts, such as bandwidth testing. The `fixed` policy requires a maximum (target) rate. Important: If `--policy` is not set, ascp uses the server-side policy setting (`fair` by default).
D	Transfer Monitor	The transfer graph. Use the sliders on the vertical axis to adjust the transfer rate up or down (if allowed).

Configuring Transfer Preferences

If you have administrator privileges, you can set the target transfer rate for all users from the Global Preferences dialog. As an individual user, you can override the global settings from My Preferences.

To update these settings, go to Tools > Global Preferences or Tools > Preferences. You can also open My Preferences from the Preferences button in the upper-right corner of the application's main window; from there you can also reach the Global Preferences dialog by clicking Global Preferences.

The following options are available under the Transfers tab:

Item	Description
Global Bandwidth Limits	The aggregated bandwidth cap for all FASP transfers on this computer. For more advanced bandwidth settings, see Bandwidth Configuration. (Set by administrators only.)
Default Target Rate	The initial download and upload rates for all transfers.
Maximum Active Transfers	The maximum number of concurrent upload transfers and download transfers.
