Advantages Of I/O Virtualization

1.1.4 I/O Virtualization It’s a technology that brings that same augmented resource utilization and flexibility of the network infrastructure.

I/O Virtualization architecture comprises of:

a) Virtual Device

b) Guest Driver

c) The communication mechanism between virtual device and stack of virtualization.

d) Real Device

e) Physical device driver

f) Virtualization I/O stack

I/O virtualization technology can be used to visualize a single physical adapter and for multiple virtual network interface cards (vNICs) and virtual host bus adapters (vHBAs). vNICs and vHBAs function like any other NIC and HBA card installed on the server. They work along with Hypervisor and applications which is the existing operating systems.

Some of the major advantages of I/O Virtualization are listed below:

a) Flexibility: Since I/O virtualization

It is said, network virtualization remains to be effective in networks that experience large, sudden, and unforeseen surges in usage.

Network virtualization (NV) uses various network resources through a logical segmentation of a single physical network. It is achieved by software installation and services to manage the sharing of storage, computing applications and various cycles. Virtualization of network treats all servers and services in the network as a single pool of resources which can be accessed without the use of its physical components. The term network virtualization is often used to explain various things, including storage virtualization, network management, and even grid computing. External network virtualization is mainly used with proper network. It affects the physical network elements like cabling, switches, network adapters, routers and so on. This remains the method to combine multiple physical networks into larger logical networks, or breaking down a single network into multiple logical
