Calculating FICON Flow Load Balance

</h1>
<a name="wp1154109"> </a><p class="pBody">
The FICON Flow Load Balance Calculator allows you to get the best load balancing configuration for 
your FICON flows. The calculator does not rely on any switch or flow discovery in the fabric. It is 
available from the DCNM-SAN Tools menu.

<a name="wp1154110"> </a><h2 class="pHeading2">
Detailed Steps
</h2>
<a name="wp1154112"> </a><p class="pBody">
To use the FICON Flow Load Balance Calculator, follow these steps:

</p>
<div class="pSmartList1"><ol type="1" class="pSmartList1">
<a name="wp1154113"> </a><li class="pSmartList1">Choose <span style="font-weight: bold">Tools &gt; Flow Load Balance Calculator</span>.

You see the Flow Load Balance Calculator. 

</p>
<a name="wp1154115"> </a><li class="pSmartList1">Click <b class="cBold">Add</b> to enter the source and destination(s) flows.
</li>
<a name="wp1154116"> </a><li class="pSmartList1">Enter source and destination using 2 byte hex (by domain and area IDs).You can copy and paste these 
IDs, and then edit them if required. 
</li>
<a name="wp1154117"> </a><li class="pSmartList1">Enter (or select) the number of ISLs between the two switches (for example, between domain ID 0a and 
0b).
</li>
<a name="wp1154118"> </a><li class="pSmartList1">Select a row to remove it and click <b class="cBold">Remove</b>.
