Why Virtualize ?
Virtual Server provides an environment where a user can run several virtual machines -
each with it is own installed operating system - on a single hardware server. The diagram below shows
how the virtual server service operates, for example, on Windows 2003 and runs one or more virtual machines. You can run NT4, 2000 and 2003 server,
desktop operating systems such as XP or Vista, and almost all flavors on Linux in a virtual machine.
Virtualization
The Host Server is the physical server and its operating system. Virtual Server is the software service installed on
the host server. A Virtual Machine is a virtualized machine run by virtual server on a host server.
It's also important to realize that virtualization isn't new, so it's a relatively mature technology.
It's been around in the PC market for several years and on IBM mainframes for a long time.
DCWireNet currently have a few farms of virtual or dedicated servers, and it is always trying to improve its own service,
preocupied in providing excellence in customer satisfaction. DCWireNet Staff is Microsoft Certified,
so you can rest assured your business will have the best technical service available in the IT market.
Fast Deployment
A virtual server consists of two hard disk files: the virtual hard drive and the configuration file.
The virtual server is great for development and test environments. Virtual server lets you create test environments very quickly
on just one or two servers. You can set up multiple test environments on the same server hardware, and quickly switch between them.
You can test a major upgrade against a current production virtual server.
Virtualization can also be used in the training environment. You can have different sets of training machines that you use for different
classes, and basic desktop PC's for running remote desktop to the virtual machines.
Mobility
Once you have a server virtualized you can move it as often as you wish. There are several backup strategies for virtual machines
DCWireNet technical staff,
will give you detailed and personalized instructions on how to better use and take advantages of your virtual server machine.
Fast Resource Provisioning
DCWireNet Virtual Server makes your life much easier and lets you change the physical resources assigned to any virtual machine either
on the fly or through a reboot. Also It allows you to add or remove memory allocation, add a new hard drive, or change the percentage
of processor used by the virtual machine.
Virtual Networks
DCWireNet Virtual Server supports a variety of networks that virtual machines can connect to.
By default it installs a network for each physical card installed in the host computer plus a network called Internal Network.
Virtual network configurations are held in .vnc files, and the location of each file is shown in the Network properties view.
Virtual Server networking runs at the layer 2 network level, so services synch as a firewall on the physical server does not affect
traffic flow to and from virtual servers.
