Is I/O Virtualization (IOV) a server topic, a network topic, or a storage topic? (See previous post.)

Like server virtualization, IOV involves servers, storage, network, operating system, and other infrastructure resource management areas and disciplines. The business and technology value proposition or benefits of converged I/O networks and I/O virtualization are similar to those for server and storage virtualization.

Additional benefits of IOV include:

  • Doing more with what resources (people and technology) already exist or reduce costs
  • Single (or pair for high availability) interconnect for networking and storage I/O
  • Reduction of power, cooling, floor space, and other green efficiency benefits
  • Simplified cabling and reduced complexity for server network and storage interconnects
  • Boosting servers performance to maximize I/O or mezzanine slots
  • reduce I/O and data center bottlenecks
  • Rapid re-deployment to meet changing workload and I/O profiles of virtual servers
  • Scaling I/O capacity to meet high-performance and clustered application needs
  • Leveraging common cabling infrastructure and physical networking facilities
