Therefore, the memory should be enough. For example, you can use the SATA-RAID 5 or raid 6, while SAS-drives provide great performance. Also make sure that the RAID-controller server supports the chosen type of RAID-array. Another point – this is a network interface. Virtualization server can be often heavily loaded with powerful stevia compounds to various sites network environment. So you need a server with at least two network gigabit controllers.
In the matter of choice of power supply should be remembered that virtualize the server it means putting all your eggs in one basket, so should be warned beforehand about the possibility of organizing a backup power supply. It is not necessary, but if your budget allows, should think about that. In the matter of choice of software you will have some free solutions for field testing of virtualization technology. VMware offers a free product, VMware Server, which runs on top of Windows or Linux. It's not quite a full solution, as it works not on the 'bare metal', but on the basis of an already installed os, but but this product is easy to install and configure. VMware also produces installed on the os without a hypervisor VMware ESXi. This powerful free product has some limitations on the equipment, so the first convolution with a list of supported devices, if you intend to use this server solution.
Microsoft Hyper-V is another alternative for virtualization in Windows-oriented networks. This product is not entirely free, because you'll first need to purchase Windows Server 2008 R2 2, but but it offers a simple and user-friendly interface and good integration with the operating system. Having bought one copy of Windows Server 2008 R2, you can arrange up to 4 virtual Windows Server 2008 and all at a price of one license. If you're using Windows Server 2008 choice of this product from a financial point of view would be justified. Also an interesting option for virtualization is Citrix XenServer. Its free version is quite functional and does not require the os to install. In general, the right approach – is to try
