I/O Virtualization: Approaches and Applications

[microbee]

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.
