In recent years, one of the big drivers behind achieving higher levels of system availability has been the development of server virtualization technology from VMware, Microsoft, and others. We will take a closer look at it in this installment.

Server Virtualization and High Availability
The ability to separate logical from physical machine operations using virtual server and application instances has provided IT managers with new tools to improve system management and availability.
For example, vSphere from VMware improves system availability with virtual software facilities that:
· Enable migration of live server instances from one physical host to another in the event of failure or declining performance.
· Move virtual machine disk files from one physical data store to another to simplify maintenance and upgrades.
· Create high availability for applications running on virtual machines with automatic re-start on alternate physical hosts should the primary physical server fail.
· Using vSphere Storage Appliance (VSA) software, create high-availability shared storage instances, eliminating the need for shared storage hardware. (However, this application does require clustered server implementation.) If a host (physical) server goes down, VSA automatically fails over to another server in the cluster, protecting against single-point failures and data loss.
