Expanding or developing an ecosystem from a point product or technology solution to a broad-reaching one is always a beneficial effort from vendors for their customers. HP’s just announced Open Network Ecosystem (ONE) is certainly a logical strategy and effort to expand basic Ethernet (some might say “data center”) switching to provide a broad array of data center and application-enabling IT services — e.g. load balancing, IP security, VoIP, WAN optimization.This is a strategy Cisco has espoused — and innovated + executed on — for years with the Catalyst, Nexus, ISR and other product families…Looking DeeperHowever, to really benefit the customer, much more needs to be done than merely host other vendors’ operating systems and code on your processing hardware and physical chassis.
