Why It's a Strategic Networking Partner: Hewlett-Packard's ProCurve Networking division continues to be one of the fastest-growing infrastructure players out there. Its lifetime warranty is the cornerstone of its value proposition, a warranty model that is so popular with VARs and end users that it has forced rival Cisco Systems to adopt a similar strategy. Cisco began offering a limited lifetime warranty on a select group of switches earlier this year in apparent recognition that HP is on the right path.
