Whiteboarding with the Woz: The Basics of Virtualization

Whiteboarding with the Woz: The Basics of Virtualization

Posted: 28 Mar 2013

Virtualization was invented in 1990, but it is still just beginning to realize its potential. Why? Because outdated storage architectures have held progress back. As Fusion-io Chief Scientist Steve Wozniak explains in this video, servers CPUs are becoming more powerful, but they can't get enough data to keep them busy.

An underutilized CPU is like a mansion with just one person living in it. The owner decides to rent out extra rooms, but the house has only one bathroom. Imagine the bottleneck when everyone tries to get ready in the morning. Using ioMemory is like replacing the one sink in the bathroom with multiple sinks. Now everyone can use the resources at the same time.

Adding ioMemory to struggling virtualization infrastructure is like replacing the old sink. Now the applications sharing the CPU don't have to wait for shared resources like storage or memory, and they can get near-instant access to the resources they need.

    WRONG - Virtualization has been around since the 1960's, but made it to the mainstream in the 1970's. Source: VMWare federal filings (10Q's and 10K's). Get your facts right - before you ghost-write for the Woz.

    Interesting but virtualization has been around since the 1960s!

      Good point! Like most great ideas, virtualization is constantly being reinvented. What started off with IBM mainframes is now available on x86 servers and even on smartphones. What's new and what has us excited at Fusion-io is that flash finally makes it possible to virtualize high-performance applications. It's the latest reinvention of a great idea.
