NetworkWorld: Cisco and several other networking vendors have been telling their customers that they'll achieve better quality and reliability if they purchase all of their network gear from a single vendor. Not true, says a new report from market research firm Gartner.
"After interviewing various organizations that have introduced a second vendor into their Cisco infrastructures, it is clear that in most cases today there is no financial, operational or functional basis for this argument," write report authors Mark Fabbi and Debra Curtis. "The reality is that a single-vendor Cisco network isn't necessarily less complex, easier to manage or more reliable than a network with multiple vendors when implemented with best practices." In fact, the report finds that companies save 15 percent to 25 percent over five years if they source equipment from at least two different vendors.
