Server virtualization creates a disparity between physical and virtual environments in terms of managing and securing data-SAN management software depends on physical attributes of devices, which virtualization masks. This white paper explains how fabric vendors must evolve their sets and operating systems so users can employ virtualization without threatening QoS, security, performance, and troubleshooting. You'll learn about virtualization offerings that can help your IT shop adapt to these challenges. Technologies reviewed include blade, switches, VMs, VSANs, and other tools that enable you to do the following:

• Improve the migration experience
• Lower TCO through more efficient resource usage
• Extend full SAN benefits to virtual networks
• Support large virtual networks without sacrificing control
