Edit throttles for hosts

You can create new throttles or change existing throttle controls for host with the management GUI.

Throttling is a mechanism to control amount of resources that are used when the system is processing I/Os on a specific host or host cluster. If a throttle is defined, the system either processes the I/O, or delays the processing of the I/O to free resources for more critical I/O. You can create or change throttles for either individual hosts or for a host cluster.

To create a new throttle for a specific host, complete these steps:

In the management GUI, select Hosts > Hosts.
Right-click a host or multiple hosts and select Edit Throttle....
On the Edit Throttle page, enter values for the following throttles:
Bandwidth Limit

Enter the maximum amount of bandwidth the host can process before the system delays processing for this host. Click Create.

IOPS Limit

Enter the maximum I/O operations per second the host can process before the system delays processing for this host. Click Create.

To change an existing throttle, complete these steps:

In the management GUI, select Hosts > Hosts.
Right-click a host cluster and select Edit Throttle....
On the Edit Throttle page, enter values for the following throttles:
