The benefits of Virtualisation

RSAWEB Virtual Servers

Virtualisation in the context of hosting has come a long way in recent years. Creating and using VM’s was once a risky business, used only by the brave on low risk projects.

These days, virtualisation is fast becoming an industry standard, as the technology behind it has matured, offering a totally robust and reliable product. Businesses across the globe are already taking advantage of the overwhelming benefits that virtualisation provides:

Better utilisation of resources
Multiple virtual servers / applications can be consolidated onto fewer sets of physical hardware, making better usage of physical resources. Though the virtual environment is ‘shared’ across physical hardware, each virtual server still has its own dedicated physical resources (RAM, CPU etc.).

Reduced risk
The architecture of Virtual environments allows for more redundancies (such as centralized SAN storage) to be built in, significantly reducing down-time in the event of hardware or software failure. Things can fail independently. For instance, one operating system can fail while others running on the same machine continue to function normally.

Virtual servers consist of a single system file, which means you can easily create a backup copy of your entire VM. If you encounter problems, you can replace your existing VM with your backup copy.

Scalability, Flexibility and Availability
The process of ‘installing’ new servers or allocating additional resources to a particular virtual server is now faster and easier to achieve, it can be done in minutes instead of having to do a physical machine upgrade and buying new hardware. We can just ‘turn it on’ by giving your system more RAM, CPU and storage.

Combined with shared storage device, virtualisation enables you to migrate from one physical machine to another without a single second of downtime allowing easier maintenance of physical hardware. Should a server have a hardware issue, the virtual machines can quickly and easily be restarted on another physical set of hardware, minimising any downtime.

It’s Greener
Better utilisation of resources reduces energy consumption in data centre environments. As much as 70% energy consumption can be achieved in most cases.

RSAWEB has extensive experience with virtualisation technology in various different applications. Many of our Dedicated Server & Managed Hosting Server customers are currently utilising virtual platforms to great effect. Give us a shout to find out how virtualisation can benefit you.

Getting the most out of virtualisation & dedicated servers

Virtualisation of dedicated servers

Thinking of a new dedicated server? Have you thought about virtualisation? Virtualisation is allowing companies to maximise server, storage and power resources. Instead of running each different application on a different set of server hardware, why not run mulitple operating systems on one machine.

RSAWeb is helping customers to maximise dedicated servers. Instead of purchasing 2-3 servers for a production / development setup, why not virtualise and use one server to do the job of many. The latest Dell XHD server from RSAWeb is extremely powerful, with 8 CPU cores and up to 32GB RAM. This can support multiple virtual machines. For example, a server with 8GB RAM allows you to run a production frontend server on 2 cores and 2GB RAM, another database server with 4GB RAM and the balance can be split amongst smaller development servers. All on 1 set of hardware!

At the same time, you will need to make sure you arent overutilising your resources, however Virtualisation has a great benefit that should you need to scale this out at a future date as your requirements grow, you can easily migrate one of the virtual servers to another physical server also running Citrix Xen (RSAWeb’s virutalisation standard) – this allows for easy flexibily, all without any reinstalling or changing of settings on the server, amazing!

Use your server in a flexible manner and cut your costs whilst also going GREEN! Using the latest AMD and Intel processors and DDR2 RAM you use less power, less cooling and benefit the environment at the same time.
