Server Virtualization
Server virtualization virtualizes one physical server into multiple logical servers, that is virtual machines (VMs), as shown in Figure 1-75.
- VM
Each VM has its own operating system and application software, and has an independent MAC address and IP address. VMs can run independently.
- vSwitch
A vSwitch provides Layer 2 communication, isolation, and QoS capabilities for VMs.
Server virtualization has the following advantages:
- Effectively improves server utilization.
- Provides services and resources on demand.
- Reduces energy consumption.
- Lowers customers' operations and maintenance (O&M) costs.
