Sort of. Virtual machines run on what is called a Hypervisor software layer on the server. The hypervisor software could be linux, unix, windows, or some other special code. Its purpose is to allow multiple virtual servers to run on one single server.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> Now they are offering hardware hypervisors on the servers to run virtual machines. Very soon and actually going on now you will see something called a Client Hypervisor. Basically you will be able to select different virtual environments and run them on your local computer which will have a hypervisor on them. Citrix just announced the release of XenClient (free to test out if you have a computer capable of running it) (check out <a href="http://www.citrix.com/xenclient">http://www.citrix.com/xenclient</a> ) Vendors are already commiting to add it to the bios of their machines.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>There are so many virtualization solutions and hypervisors out there it is getting mind boggling.

Just like in the days of the VMS Vax.. Everything old is new again, the 70’s/80’s are back. The names may change and the products may get more convoluted but they are basically doing the same thing they have been for a very long time and that is using one server to run multiple server hardware/OS virtually off its disk array. Now imagine that at the client level and that is where the paradigm starts to shift and differ. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Regards,<o:p></o:p></span></p><p class=MsoNormal style='text-autospace:none'><b><span style='color:#1F497D'>Jim Kenzig<o:p></o:p></span></b></p><p class=MsoNormal style='text-autospace:none'><i><span style='font-size:10.0pt;color:#1F497D'>Software Applications Engineer</span></i><i><span style='font-size:11.0pt;color:#1F497D'><o:p></o:p></span></i></p><p class=MsoNormal style='text-autospace:none'><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D'>Cuyahoga County Public Library<o:p></o:p></span></p><p class=MsoNormal style='text-autospace:none'><span style='font-size:10.0pt;color:#1F497D'><a href="www.cuyahogalibrary.org">www.cuyahogalibrary.org</a></span><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> oplintech-bounces@oplin.org [mailto:oplintech-bounces@oplin.org] <b>On Behalf Of </b>Eric Maynard<br><b>Sent:</b> Friday, May 28, 2010 9:28 AM<br><b>To:</b> Oplintech@Oplin.Org<br><b>Subject:</b> Re: [OPLINTECH] Community Library now running VMware ESXi<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Bob/Chad,<o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>I'm probably not as knowledgeable on this as I could(should) be, so please forgive if I am asking the obvious to someone who is, but I was curious why you chose VMWare over say something like Ubunutu Server's visualization capability?<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><a href="http://www.ubuntu.com/server/features/virtualisation">http://www.ubuntu.com/server/features/virtualisation</a><o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal style='margin-bottom:12.0pt'><br clear=all>Eric Maynard<br>Head of Information Technology,<br>Holmes County District Public Library<br>Millersburg, OH 44654<br>Email [<a href="mailto:emaynard@holmeslib.org">emaynard@holmeslib.org</a>]<br>Phone [330.674.5972 x.224]<br>Fax [330.674.1938] <br><br>"Failure is only the opportunity to begin again more intelligently"<br><br><br><br><o:p></o:p></p><div><p class=MsoNormal>On Fri, May 28, 2010 at 9:07 AM, Bob Neeper <<a href="mailto:neeperro@oplin.org">neeperro@oplin.org</a>> wrote:<o:p></o:p></p><p class=MsoNormal>REF: <a href="http://www.vmware.com/products/esxi/" target="_blank">http://www.vmware.com/products/esxi/</a><br><br>System was a beefed up Windows 64bit server running VMware to manage 7<br>to 9 virtual servers.<br>As part of an upgrade, Windows was to be replaced by ESXi (free version)<br><br>Last weekend Chad (Level 9 Networks) began the server upgrade.<br>Short version:<br> Backed up everything<br> Broke the existing raid into 2 pairs of mirrored drives<br> Added a 2TB drive (1 more still to add)<br> Reformatted main drives, installed ESXi<br> Restored the virtual servers<br><br>System performance has noticeably improved !!<br>Some examples:<br> Backup to tape shaved 30 minutes of the circulation server backup<br> openSUSE Education (children's dept.) thin clients response greatly<br>improved<br> External response from our websites and PAC greatly improved.
