# Host I/O limits dialog box

This dialog box is used to set the host I/O limits for the storage group that is being provisioned.

## About this task

## Steps

1. Type values for one or both of the following:
   - MB/Sec—Maximum bandwidth (in MB per second). Valid values range from 1 MB/sec to 100,000 MB/sec.
   - IO/Sec—Maximum IOPS (in I/O operations per second). Valid values range from 100 I/O/Sec to 2,000,000 I/O/sec, in 100 increments.
2. To configure a dynamic distribution of host I/O limits, set Dynamic Distribution to one of the following; otherwise, leave this field set to Never (default).
   - Always—Enables full dynamic distribution mode. When enabled, the configured host I/O limits are dynamically distributed across the configured ports, allowing the limits on each individual port to adjust to fluctuating demand.
   - OnFailure—Enables port failure capability. When enabled, the fraction of configured host I/O limits available to a configured port adjusts based on the number of ports that are online.
3. Click OK.
