Network I/O Challenges of Data Center Virtualization

Fundamental changes are occurring in the data center, and these changes will have dramatic and lasting affects on how we think about designing computer networks and hosting platforms. In previous years, servers simply acted as application hosting devices. Owing to the explosion of multicore CPUs and virtualization, the server needs to look more like a hardened network element with the ability to perform extensive networking and security processing. A missing element in these designs is the server’s I/O. IT architects need to consider how to link virtualized network infrastructure and virtualized server platforms without degrading performance.Forms of Virtualization through the YearsThe term virtual machine (VM) was first used in the 1960s, and since then, the use of varied forms of ...
