In this very first post on the VMware series, I would like to
focus and discuss the fundamental concepts of virtualization and review the
VMware virtualization implementation options.
1. VMware Server (It is not a bare metal
Installation)
VMware
Server runs on top of an existing host operating system (either Linux or
Windows). This is a good option to get started, as you can use any of the
existing hardware along with its OS. VMware server also supports 64-bit host
and guest operating system. You also get VMware Infrastructure web access
management interface and Virtual Machine console.

2. VMware ESXi (Bare Metal Installation)
VMware ESXi is based on the hypervisor architecture. VMware ESXi
runs directly on the hardware without the need of any host operating system,
which makes it extremely effective in terms of performance. This is the best
option to implement VMware for production usage.

Following
are some of the key features of VMware ESXi:
§ Memory
compression, over commitment and deduplication.
§ Built-in
high available with NIC teaming and HBA multipathing.
§ Intelligent
CPU virtualization
§ Highly
compatible with various servers hardware, storage and OS.
§ Advanced
security with VMSafe, VMKernel protection and encryption.
§ Easy
management using vsphere client, vCenter server and command line interface
In my next post I will define the basic term used in VMware such
as Host, Guest, VMs, Snapshot, Template, and Clone etc. I will also try to
focus on there working architecture.
