I don't agree that vmware is vital to hadoop clusters, or storage. since the HDFS was designed to run on inexpensive hardware and local storage,
Amazon use zend as the basis for their virtual environment,
my point is that with hadoop running on cheap hardware, in clusters, and using local storage, this could mean the decline of SAN, as more data been generated is unstructured, like from social media, sensors, and the internet of things.

Hi John;

I think you're conflating two issues.

Yes, Hadoop (and HDFS) are designed to run on scale-out commodity hardware -- that's true.

But as anyone will tell you, these environments are not trivial to spin up and manage, and they're somewhat wasteful of resources -- even though they are commodity resources. That's where virtualization (and VMware) can help.

I would agree with you than in these newer environments, storage networking tends to look different than the familiar SAN, but that doesn't mean that SAN goes away, only that it's joined by other models depending on workload.

There are still plenty of mainframes out there, for example :)
