VMware ESX is an enterprise-level computer virtualization product offered by VMware, Inc.

VMware ESX is an enterprise-level computer virtualization product offered by VMware, Inc. ESX is a component of VMware's larger offering, VMware Infrastructure, and adds management and reliability services to the core server product. VMware is replacing the original ESX with ESXi.

VMware states that the ESX product runs on bare metal. In contrast to other VMware products, it does not run atop a third-party operating system, but instead includes its own kernel. Up through the current ESX version 5.0, a Linux kernel is started first, and is used to load a variety of specialized virtualization components, including VMware's vmkernel component. This previously-booted Linux kernel then becomes the first running virtual machine and is called the service console. Thus, at normal run-time, the vmkernel is running on the bare computer and the Linux-based service console runs as the first virtual machine.

iSCSI SAN Implementation with several ESXi hosts and two Equallogic SANs

I work for a small state college. We currently have 4 ESXi hosts (all made by Dell), 2 EqualLogic SANs (PS4000 and PS4100) and a bunch of old HP Procurve switches. The current setup is very far from being redundant and fast so we want to improve it.…

VMWare: ESX or 3i? Do I need the COS?

We have lots of regular ESX 3.5 hosts but I'm about to take delivery of a bunch of Xeon 55xx based servers and think it's time to question whether to use 3i in the future. It would save me buying local boot disk pairs and most of the patches are to…
