Eric Siebert has been working with computers for more than 25 years. For the past 15 years, his main focus has been the administration of Windows server environments and supporting enterprise applications such as web, email, and database servers. Four years ago, he discovered virtualization technology in the form of VMware ESX and has been hooked ever since, spending countless hours learning the product inside and out. He now spends much of his time helping others in VMware’s community support forums, having achieved Guru status and become one of the forum’s moderators. His own website, http://vmware-land.com, is where he shares his tips and experiences and hundreds of links to technical information and top ten lists on a variety of subjects. In addition, Eric writes tips and blogs for Tech Target on sites such as searchvmware.com, searchservervirtualization.com, and searchdatabackup.com. Most recently, he was a speaker, panelist, and Best of VMworld awards judge at VMworld 2008 and is a regular guest on VMware’s weekly VMTN roundtable podcast. In 2009, Eric was awarded the VMware vExpert award, one of only 300 people worldwide recognized for their knowledge, experience, and contributions to the VMware community.
