According to McCool's latest blog: "With the introduction of the Cisco Nexus family in January 2008, we also announced the concept of Unified Fabric as a fundamental building block for the data centre. We offered the simple vision of a single fabric to link all the network, compute and storage resources in a data centre as a mechanism to not only reduce TCO but also improve agility and flexibility.
"Since then, we have released a steady flow of products and technologies to deliver on the promise of Cisco Unified Fabric by simplifying the infrastructure with convergence, improving its ability to handle virtual and physical scale and increasing the intelligence of the fabric to increase agility and lower operating costs."
He claimed: "Other vendors in the marketplace are left to play catch-up. In a November 4, 2010 independent report titled 'Q&A: Networking Landscape, Q4 2010' Forrester Research commented that: "To Cisco's credit, it saw the data centre evolution way before any other networking vendor and started to build a set of products and solutions directed at a converged and virtual world."
And he cites a Gartner research note 'Fabric Computing Poised as a Preferred Infrastructure for Virtualization and Cloud Computing' (published just prior to the announcement of QFabric) that urges customers: "Do not overhaul or plan on rip-and-replace fabric development, but impose on vendors' design guidelines that harmonize their solutions with your other data centre infrastructure."
