How reliable is the Hypervisor - Dissertation Example Each of the ports can be customized to function in the manner desired by the user to suit the requirements intended. In the virtual networks, the vSphere standard switch functions as the physical Ethernet switch. It senses the virtual PCs appropriately linked to every virtual port and uses the signals to control the network. The hypervisor technology of VMware vSphere 5 serves a significant function in the management of the virtual network systems. The invention of bare-metal VMware ESX in 2001 extensively improved the effectiveness and reliability of networks, which in turn drew several users into the application of the technology in generating virtual technology. The hypervisor has raised the standards for security and efficiency of virtual networking systems due to its magnificent performance. ESXi can be integrated in several network application to facilitate improvement of quality in service provision and to increase the centralized of administration services. This paper outline s the creation of a virtual network using Vmware ESXI 5 and installed in three OSs; Windows 7, Windows xp 32-bit and 64-bit in a real scenario. It also outlines the security hardening of the hypervisor using various security measures including nmap software. The paper further outlines the advantages and disadvantages of the Vmware ESXI 5 by conducting a SWOT analysis of the virtual network created. 4 Chapter 1 5 1.1Introduction 5 VMware maintains the leading position as the supplier virtualization solution via their vSphere suite of services founded on the ESXi hypervisor (VCRITICAL, 2010). The fifth edition of the product is the most useful of all because it provides the user with the most remarkable service that one can imagine. Although the software is offered free without any restrictions or limitations, users are required to login into VMware website and register to acquire a license key to download, install and activate the product. The new ESXi has several features, which giv e its users a wonderful experience in their applications. One should consider a few issues before installing the software. One of the issues is whether the hardware is compatible with the product and sufficient to run the product and whether the OS installed in the PC is adequate to run it. It is thus necessary to consider the hardware requirements for this product because it is critical towards the running of the product. The VMware ESXi when installed in a system hardware, provides a strong virtualization experience between the hardware and the OS. ESXi normally divides a physical server into several protected and moveable virtual systems that can operate alongside each other on the one physical server. Every virtual system stands for a whole system composed of processors, RAM, networking and BIOS in such a manner that an OS and software features can be set up and operated in the virtual system without any customization (VCRITICAL, 2010). Virtual systems are also entirely separate d from one another by the virtualization cover thus avoiding a situation where a malfunction of one of them distresses the others. The distribution of physical server essentials among several virtual systems enhances hardware use and surprisingly cuts on the operational expenses. The virtual networking ability of the ESXi enable users to create multifarious networks among virtual systems linked to one host or
