Server Virtualisation

Server virtualisation is a proven technology that enables multiple virtual machines  to run on a single physical server. Each virtual machine is completely isolated from other virtual machines and is decoupled from the underlying host by a thin layer of software known as a hypervisor. This allows each virtual machines  to run different operating systems and applications. Because the machines have been decoupled from the underlying host, the guest can also be moved from one physical server host to another while running; this is known as live migration. These attributes are transforming how organizations approach virtual computing.

Moving to a virtualised environment allows hardware to be aggregated into a unified pool of IT resources that can be dynamically delivered to systems and applications as needed, and according to fluctuating workloads and network conditions. This enables organisations to boost their utilisation of processing power, decreasing the number of servers and hardware required and delivering savings on space, power, cooling and ongoing support costs.

Thanks to virtualisation, the days of bringing down applications for scheduled server maintenance are over. Using virtual motion technology, entire virtual environments can be transferred to a backup server without disruption, allowing our IT experts to proceed with maintenance or even server replacement without affecting service delivery.

Virtual machines can be more easily and flexibly controlled and configured than physical systems, allowing users to introduce new systems, applications and upgrades in response to changing business needs faster than ever before. Users can provision virtual machines as required without the need for an up-front hardware purchase, and new applications can similarly be delivered in a matter of minutes, rather than days or weeks.

Key Benefits

• Get more out of your existing resources

Pool common infrastructure resources and break the legacy “one application to one server” model with server consolidation.

• Reduce data centre costs by reducing your physical infrastructure and improving your server to admin ratio

Fewer servers and related IT hardware means reduced real estate and reduced power and cooling requirements. Better management tools let you improve your server to admin ratio so personnel requirements are reduced as well.

• Increase availability of hardware and applications for improved business continuity

Securely backup and migrate entire virtual environments with no interruption in service. Eliminate planned downtime and recover immediately from unplanned issues.

• Gain operational flexibility

Respond to market changes with dynamic resource management, faster server provisioning and improved desktop and application deployment.

• Improve manageability and security

Deploy, manage and monitor secure desktop environments that users can access locally or remotely, with or without a network connection, on almost any standard desktop, laptop or tablet PC.
