It shows you how to manage system upgrades, maintenance and administration — including system integrity."?John Vacca, information technology consultant and author of High-Speed Cisco Networks: Planning, Design ,and Implementation "The authors are providing a framework for analysis, critical evaluation and a practical approach to selecting technology for your enterprise.
