Mendel Rosenblum is a co-founder of VMware, a Stanford University professor of computer science, and chief science officer for the market leader in virtualization. At VMworld, the annual VMware user group meeting this week in San Francisco, Rosenblum talked with InformationWeek Editor at Large Charles Babcock about the latest version of the ESX Server hypervisor and how VMware plans to cope with Microsoft(MSFT)'s entry with Viridian into the market next year.
InformationWeek: VMware put ESX Server on a weight loss plan to get it down from two gigabytes to 32 megabytes in the just announced, embeddable, 3i version. How did you do that?
Rosenblum: We've typically included a version of Red Hat Linux in ESX Server. That's because the hardware manufacturers put little embedded processors to control the fans and other elements of their servers. They have agents reporting on their operation. They wouldn't write software that would allow those processors to interface to ESX Server, but they had to do it for Linux. So we shipped a full Red Hat operating system as our management console.
