High availability used to be expensive, requiring both specialized software and redundant hardware. Today it almost grows on trees, but you need two key ingredients: virtualization and network storage. By creating a virtual server farm across multiple physical servers, and storing all of your virtual machines on a central SAN or NAS, you can ensure that the failure of any given piece of physical hardware will not bring down your virtual environment. We recently created a highly available virtual server cluster based on the free edition of Citrix XenServer; this article outlines the process step by step. Although the obvious choice for any enterprise-grade virtualization deployment is VMware vSphere, I chose XenServer for two reasons. First, we're cheap. We don't like spending money on things that we can get for free. Second, and more important, the licensing of VMware is extremely confusing; we're never sure what exactly is required to be properly licensed. (I guess...

Citirix XenServer is a hypervisor platform that enables the creation and management of virtualized server infrastructure. It is developed by Citrix Systems and is built over the Xen virtual machine hypervisor. XenServer provides server virtualization and monitoring services. It is available in a 64-bit hypervisor platform and can be executed on the entire x86 series of processors. Cirtix XenServer is among the virtualization solutions provided by Citrix Systems, which consolidates a physical server's computing power into multiple virtual machines, all emulating as a standard server. Citrix XenServer is built to provide the operational requirements of a standard server and supports most server operating systems, such as Linux and Windows Server, on guest server machines. Through its virtual machine monitoring component, Citrix XenServer manages the allocation and distribution of physical server computing resources among virtual machines and administers their performance an...

In previous Blog we have seen what is Hyper-V and the use of VMs, And here we are moving forward with the Benefits of Hyper-V and required Hardware to create it. If still you have not read previous Hyper-V blog than before going through this blog you should read the previous one before to understand the functionality. So by click on What is Hyper-V you can read the whole article of it. Benefits of Hyper-V One of the primary reasons organizations turn to Hyper-V is because it’s cost-effective—in fact, the basic Hyper-V tools are free with an enterprise agreement (EA, a volume licensing package offered by Microsoft for organizations with 500 or more computers). You will have to pay for more advanced Hyper-V functions and licensing, but even so, Hyper-V still has an edge over its competitors when it comes to price. Hyper-V is even more attractive when you consider its similarities with its biggest competitor, VMWare. Because Hyper-V is a solid, cost-effective option, many bu...
