Virtualization has brought a lot of gifts to the IT department. It makes it impossible not only to become possible, to become more popular. From server consolidation to cloud computing, virtualization is currently the dominant computing platform in the world. In addition to expanding computing power, virtualization is also considered a way to increase

If all virtual machines are considered to be physical machines, then on the network topology, different network connection devices and methods

operation business can be quickly recovered. If the hardware is damaged or the virtual server is on the machine, you only need to reconstruct the storage virtual image of the environment to quickly restore business operations. Since virtual machines are based on abstract hardware independence, a backup server can restore the Business Operation Systems on different hardware platforms without worrying about hardware compatibility issues. Security Testing. For security management, establishing sec

If you want to implement the vision of a software-defined datacenter, network virtualization will be the last mile in the journey. IDC estimates that the network virtualization market will grow from 2013 360 million dollars to 2016 3.7 billion. Many giants have been a big hit, and a lot of new companies are also target

Now you can take a sigh of relief. Software Defined Network (SDN) has become a reality, because Cisco has finally begun to "Embrace" it, which also marks the end of all kinds of "Cynicism. However, I cannot help but think of network virtualization because Cisco promotes the development of SDN. Network

As enterprises move towards server virtualization, does the VoIP/ipserver adapt to the server consolidation plan? The answer is yes. PBX (Programmable switch) was previously an independent proprietary system. With the emergence of Internet protocol Voice Technology (VoIP) and network telephone technology (IPTS), PBX has become a system-based server. Why Should organizations and their ability to virtualize V

When network virtualization is insufficient to solve the problem Consultant Glen Kemp shared a case where a customer re-evaluated the benefits of network virtualization after encountering a platform Bug. Iteration of any new technology or existing technology will make events faster, cheaper, or less costly. Server

Nearly 60% of enterprises have slowed down their virtualization plans, according to nemertes's latest survey. The complexity of the system, especially the complexity of network configuration, is usually considered the biggest obstacle to virtual network deployment. However, virtual networks can help enterprises configure virtual networks and completely define the

Network virtualization is now a hot topic, and major manufacturers are scrambling to grab this cake. Technologies involved include virtual Emulation for NICs, I/O pass-through, SR-IOV), virtual access technology for networks VN-Tag/VEPA), covering network switching VXLAN/NVGRE ), and Software Defined network SDN/OpenFl

First, the network hardware that constitutes the physical network structure needs to transmit IP data packets. This is important and will never change. No matter whether network virtualization is deployed or not, hardware is required to transmit data packets between systems in the data center. Although many
