I/O is a key element of server architecture, but its virtualization is only now starting to be addressed. Without I/O virtualization, the amount, type, and physical connectivity of server I/O are all fixed. In order to achieve true flexibility in server usage, these fixed resources must become dynamic. This enables an on-demand usage model for non-virtualized servers, including failover with shared spares, and server pool scaling. It is also an important complement to virtual machine technology, providing flexible dedicated I/O pipes for virtual machines. This presentation will compare different approaches to I/O virtualization and discuss the applications of the technology.

Speaker Bio: Ariel Cohen is the CTO of Xsigo Systems. Previously, he was at Topspin Communications (acquired by Cisco). His areas of expertise are networking and I/O. He holds a PhD from UCSD, he authored papers and patents in the areas of storage systems, I/O virtualization, web switching, and RDMA protocols.

3rd International "Virtualization Conference & Expo" Call for Papers
Virtualization, the hottest subject in all IT right now, will be center stage in 2008. Key opinion-formers in the field of infrastructure and pioneers of virtualization technologies of all types have already begun submitting speaking proposals to Virtualization Conference & Expo 2008 East, being held in New York City, June 23-24, 2008. Topics covered will range from Application Virtualization, Desktop Virtualization, Network Virtualization, Server Virtualization, and Storage Virtualization, to Virtual Machine Automation, Physical to Virtual (P2V) Migration, Management Applications, Tools and Utilities, and Virtualization Scripts and Procedures.

Submissions on these and dozens of other topics have already begun streaming in. The Call for Papers is as always a 100% online process, found here.

IDC has stated that the virtualization services market alone is going to reach $11.7 billion by 2011 and in general this technology, which has been around for a good number of years, seems suddenly to be on everyone's mind.

In short, Virtualization is fast becoming a key requirement for every server in the data center, enabling increased workloads in server consolidation projects, efficient software development and testing, resource management for dynamic data centers, application re-hosting and compatibility, and high-availability partitions. Help with that transformation: submit your speaking proposal today.

Topics will include:

• Server Virtualization
• Desktop Virtualization
• File Virtualization
• The Future of the Virtual Enterprise
• Hosted Virtualization
• Para-virtualization
• Virtualization Hardware Support
• Hardware-level Virtualization
• Storage Virtualization
• Virtualization for Server Consolidation and Containment
• Windows Virtualization
• Utility Computing
• State of the Virtualization Services Market
