		<description><![CDATA[I wanted to take a few minutes to point out the 17 different load balancing algorithms available when distributing traffic from a VMware vSphere ESX host to a network of clustered upstream switches.  Normally I don&#8217;t write blogs on such short topics but this one has a little story behind it.

		<description><![CDATA[This article is a simple examination of the fundamental differences in how server bandwidth is handled between the Cisco UCS approach of QoS (quality of service), and the HP Virtual Connect Flex-10 / FlexFabric approach of Rate Limiting.  I created two simple flash animations shown below to make the comparison.

The animations above are each showing [...]]]></description>

This presentation assumes familiarity with basic networking and server VNIC concepts in UCS, and familiarity with virtual port channels.
