Load distribution across host ports
Load distribution across host ports provide information about the usage of all the host ports belonging
to both controllers. It enables you to identify whether the I/O load across all the host ports are well
distributed.
You can select either Controller 1, Controller 2, or Controller 1 and Controller 2 and the time
duration for which you want to view the load distribution. Each controller can have a maximum
of four host ports and the load distribution data displayed is based on the selected option. The
default option is Controller 1. Apart from the default time duration of 1, 6, 12, or 24 hours, you
can also retrieve information for any custom duration within 24 hours.
The host port metrics includes the following:
•
Total Req/s
For each host port on each controller, this calculated metric records the total number of requests
(Read and Write) received during the selected sample interval.
•
Total MB/s
For each host port on each controller, this calculated metric records the total data rate (read
data rate and write data rate) during the selected sample interval.
NOTE: The data displayed for both the metrics is historical.
Based on the number of host ports present in a controller, the line and pie charts are displayed.
•
Line Chart: Displays the trend of the data within the selected time interval.
•
Pie Chart: Displays a comparative view of the load across all host ports for the same time
interval.
