D ATA S H E E TSANbox 9000 Series
SANbox® Product FamilyThe new look for powerful, easy to manage fabrics
The SANbox 9000 is the flagship in the SANbox line of fabric switches, intelligent storage routers, and storage ser-
vices platforms. As individual components, every QLogic SANbox delivers the advantages of a best-in-class product.
Working together as an intelligent network solution, they are easy to deploy and administrator and they make your
SAN perform better, too. That’s why the entire QLogic SANbox line won the Windows IT Pro “Readers Choice” award.
For your switched fabric, you can count on QLogic for exactly the right switch…from the core, to the distribution
layer, to the edge. For low-cost local and remote server connectivity, QLogic Intelligent Storage Routers boost utili-
zation while driving down cost and complexity. And for storage virtualization, the QLogic Storage Services Platform
offers network-based command and control of your heterogeneous storage. By virtualizing storage from within the
fabric, you greatly simplify management. More importantly, you ensure an open environment that can accommodate
multiple vendors, new solutions and future flexibility.

How does Wi-Fi work?
Radio waves
Circular signal, like a rock in a pond
Different devices = different signal strengths = different circle sizes
Different devices = different antenna strengths = differing ability to detect signals

Locate the phone Join wireless network or plug into ethernet
You tell person the code language in which to speak
Have a conversation
Special software creates an encrypted connection between your computer and the wireless
access point
Start sending and receiving data
