		<description><![CDATA[Ok, I have no problem with tape.  It&#8217;s a *GREAT* backup medium when your requirement is portability for massive amounts of data and you&#8217;re not replicating said data. If I had to ship 400TB of backups to Iron-Mountain, to protect against the earthquake-to-end-all-earthquakes tape would be my FIRST choice (though maybe, as a GIANT CAVE [...]]]></description>

		<description><![CDATA[Ok, given the changes to the storage arena I&#8217;ve been working on a revised &#8220;Tiering system&#8221; to incorporate all of the levels of data&#8230;importance? My version of Storage Tiering is (or should be) as follows: Tier-1    &#8211; Symmetrix/Replicated &#8211; High Performance/Criticial Data Tier-2    &#8211; Symmetrix/NonReplicated &#8211; High Performance/Non-Criticial Data Tier-3   &#8211; Symmetrix/SATA/Replicated &#8211; High-Medium Performance/Critical [...]]]></description>
