Advantages
Host Systems
• Reduced complexity
Host access • one point of administration
Disadvantages
• Potential performance
issues with data path
Virtualization
Engine
“pinch point”
• Adds a potential point

The other option is symmetrical or in band in the network. It is probably going
to support more Operating Systems because we don’t need an agent. The
metadata request and the actual data I/O goes through the device. They can
either be software or hardware based solutions. They can even be switch
based.
