		<description><![CDATA[Today I want to show what kind of IO performance we can get from Oracle Database Appliance (ODA). In this part, I will focus on hard disks. That&#8217;s right &#8212; those good old brown spinning disks. I often use Oracle ORION tool to stress-test an IO subsystem and find it&#8217;s limits. It&#8217;s a very simple [...]]]></description>

In that session, there was a section on how to determine I/O throughput for a system, because in data warehousing I/O per second (iops) is less important than I/O throughput (how much [...]]]></description>
