Server Virtualization

Server Virtualization

Server virtualization virtualizes one physical server into multiple logical servers, that is virtual machines (VMs), as shown in Figure 13-22.

Figure 13-22  Basic architecture of server virtualization
  • 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.
