Manage a Host

Use the following tasks to manage a host.

Item Description
1

This button adds a new host (see Add a Host).

A host is what you assign as either a source or target system.

Note: The host's flexsyncd daemon must be running and reachable at its configured DNS name or IP address to successfully complete this task.
2

This button manages a registered repository (see Manage a Registered Repository).
3

This button resumes a host (see Resume a Host).

When you resume a host, then all replication tasks associated with the host are resumed.
4

This button suspends a host (see Suspend a Host).

When you suspend a host, then all replication tasks associated with the host are temporarily paused.
5

This button edits the name (label) of a host (see Edit a Host).
6

This button deletes a host (see Delete a Host).

    Description

    Bandwidth Throttling

    Select this option to restrict the bandwidth across all of the active tasks for the selected host, to the specified value.

    • By default, bandwidth throttling is disabled. To enable:

      1. Check Bandwidth Throttling.

      2. In the Bandwidth limit field, enter a value.

        Note: The minimum bandwidth limit value is 1 MiB per second (MiB/s).

      3. Select a data transfer rate from the list.
    • Enter 0 to disable bandwidth throttling.

    Note: If you enable bandwidth throttling, the rate I/O is not guaranteed. Initially, your data transfers might experience a bit of variation where the host’s transfer rate, as shown in the GUI, can be slightly higher or lower than the requested transfer rate. The transfer rate eventually settles in to the requested transfer rate. Also, the transfer rate shown by the GUI is an average across the running time of all active tasks. If you update the bandwidth limit mid-stream, then FlexSync throttles up or down to that limit immediately, but it might take an extended period of time for the average to reflect the updated bandwidth limit.

    Caution: Use caution if you attempt to mix Bandwidth Throttling and Storage Manager. If you run FlexSync on a throttled link or if the link is substantially slower than the minimum tape drive read speed, see Considerations for Low Network Bandwidth Tape Retrieval for configuration options.
