Key Components of Server Virtualization

Server virtualization provides a means to consolidate multiple virtual systems and their workloads onto one or more physical systems. Server virtualization allows server systems to be packaged as a collection of files that establish what is known as a virtual machine (VM).

We should all thank technology providers for bringing server virtualization to the data center. In 1968, IBM created a new mainframe that was the first OS supporting virtualization. Then, VMware brought server virtualization to the data center in 2001. Not only VMware but also other companies like Microsoft, Oracle, and Red Hat have supported virtualization technologies to get a place in this market.

• Oracle VM for SPARC or LDOM’s
• Xen
• KVM
• Microsoft HyperV
• VMware ESXi

Virtualization effect on data center:

• Less server
• Consume less power
• Take up fewer spaces on data center
• Easy to maintain and operate infrastructure
