Moving From VMware ESX Platform to Microsoft Hyper-V
it has been almost 3 years since we been using VMware ESX as our virtualization platform. currently, we have three ESX 4.0, and one 3.5 ESX hosts and a total of about thirty VMs. all the VMs on these ESX hosts are being hosted from a Dell SAN. I was not part of the initial virtualization planning team, but I … Continue reading
VMware ESX Host Server Performance Slumped By a VM

What’s The Different Between ESX And ESXi
VMware makes available two bare-metal hypervisors; ESX and ESXi, which form the foundation of their virtualization product line. both hypervisors do the same thing when it comes to virtualization, they only differ in packaging.

Installing ESXi 4.0 On a 32-Bit Processor
Today I purchased a couple of old servers on craiglist to setup my home testing lab. one of my plan is to setup ESX on one of these servers and setup the other one as a SAN ( more on this later). the first thing I tried to do was to install ESXi 4.0 but somehow the installation was halted … Continue reading
