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.
