		<description><![CDATA[New technologies, new toys &#8212; Oh how I love getting my hands dirty with them. Today I am going to have a look at ATA Over Ethernet (AoE) as an alternative solution to NFS in the role of a NAS/SAN implementation. We will look at both the server side vblade setup and the client side <a href="http://www.rfxn.com/ata-over-ethernet-as-an-alternative/" class="more-link">More &#62;</a>]]></description>

		<description><![CDATA[It used to be all the talk, everyone knew it, accepted it but few did anything about it and still even today, very few do anything about it. What is it? Data Integrity. But it is not in the form of how we usually look at data integrity; it is not backups, raid management or <a href="http://www.rfxn.com/data-integrity-aide-for-host-based-intrusion-detection/" class="more-link">More &#62;</a>]]></description>

This is an otherwise very reliable method to keep out random unallocated spoofed addresses from injecting traffic towards your server, assuming of course the list is updated regularly.
