    <description>&lt;P&gt;&lt;STRONG&gt;Hoa had an iSCSI question:&lt;/STRONG&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;****************&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;With iSCSI we recommend &lt;STRONG&gt;either&lt;/STRONG&gt; Flow Control or Jumbo Frame.&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; With VC downlink ports flow control enable by default, not uplink ports.&amp;nbsp;&amp;nbsp;&amp;nbsp; To enable this feature, it seems to me that ALL VC ports up and down links will be enabled.&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; We’ll use only two ports from VC Flex-10 for iSCSI AND NFS, Flex LOMs for ESX traffics.&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;Is&amp;nbsp; it ok set flow control globally for VC?&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; I must enable this feature for all iSCSI components related components (switches,&amp;nbsp; iSCSI Storage system)&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;****************&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;STRONG&gt;Info from Aric:&lt;/STRONG&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;***************&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Flow control is enabled by default with VC.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;***********&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;STRONG&gt;Any other help?&lt;/STRONG&gt;&lt;/P&gt;</description>
