While I am not as garrulous or descriptive as Mike, I should at least introduce myself. My name is Les and I work as an IT Administrator with Mike, but have only been there for about 5 years; Before that I was in the private sector.
Since starting I have had various duties including administering sendmail and EMC Networker to more recently DNS/DHCP and high performance computing in addition to being the local Linux expert. About three and a half years ago my boss asked if I wanted to play with this new virtualization thing, and of course I said yes. We started with a single host running VMware Server and have since graduated to 72 hosts (including the new Flexpods) running vSphere4. I enjoy the challenges and strive to automate myself into the unemployment line, but as long as there are challenges I am having fun.
