Virtualisation

Redcentric delivers across all the key virtualisation disciplines including virtualised desktop, server, applications and storage, and is one of the leading virtualisation suppliers in the UK. Expert in the key VMware, Citrix and Microsoft Hyper-V Virtualisation technologies, Redcentric is a Gold-accredited Citrix Virtualisation Supplier in the UK.

Virtualisation is not just for global IT infrastructures as virtualisation addresses fundamental issues and inefficiencies found in organisations of any size:

  • Low server utilisation levels
  • Limited space to develop infrastructure
  • Lack of budget to purchase new hardware
  • Inefficient or absent backup/restore capabilities
  • Spiralling power and cooling expenses
  • Ineffective processes to build and deploy desktop devices and servers

Virtualisation was identified in a recent CIO survey as a key infrastructure necessity for CIOs to cut costs and reduce wasted power over the next 12 months.

What is virtualisation and what can it do for me?

Virtualisation consolidates hardware devices in a logical environment. For instance, one virtual network device could take an image of a physical network rack making a digital version, and keep all the devices separate in its memory.

But, why have a virtual version instead of an actual one? Virtualisation boosts the capacity of IT infrastructures in a cost and space efficient way.

Key benefits of effective virtualisation and deploying IT services over a virtual environment:

  • Device Consolidation: operating multiple applications on common hardware, reduces the number of servers required to support applications
  • Reduced Operating Costs: Reducing server power and hosting space costs
  • Rapid Deployment: Applications can be deployed rapidly without the need for additional infrastructure
  • Automated Disaster Recovery: Virtual Machines can automatically failover to other physical servers
  • Infrastructure costs can be reduced by reducing and combining the number of servers and amount of storage hardware needed to run applications
  • Introduce always available, on demand applications and desktops to information workers from any location, device and connection
  • Reliable business continuity and disaster recover solutions can be applied simply and efficiently
  • Administration and IT management can be simplified
  • Implement green IT policies that dramatically reduce the amount of power, space and cooling required to run IT systems

Why use virtualisation?

Rapid growth in x86 servers and the infrastructure (networking, storage etc) has in a lot of cases created an infrastructure that is difficult to measure and monitor. Therefore many IT departments lack the information needed to assess the suitability of their environment to a virtual infrastructure.

Based on cross-section of organisation environments:

  • 5-10% processor utilisation
  • 3x average peak hour utilisation
  • System capacity much greater than usage requirements
  • 20-50% more physical servers found
  • 40% servers >3 years old
  • 28% servers <700mhz

Virtualisation assessment

A formal assessment of your existing and planned resources and virtualisation needs should be done before attaining a virtualisation solution. How virtual machines will be distributed across physical computers can be determined using capacity planning for optimal performance and ease of management.

Your assessment should answer the following questions:

  • How many servers do you have?
  • Which roles do they serve: application, database, web, etc?
  • How many servers do you need?
  • How many users do you serve?
  • Do you have any issues with your current servers?
  • Do you want to streamline any processes?
  • Which server utilisation trends have you observed?
  • What percentage of your resources are underutilised and for how long, on average?
  • Which usage patterns would you prefer to see?
  • How much of your existing infrastructure can you virtualise?

My environment doesn't seem suitable for a virtual infrastructure?

The majority of x86 environments can benefit from virtualisation, yet there are certain servers and workloads which are not suitable. If this is so, Redcentric will work with you to find an alternative solution.

Shared virtual hosting service

The same features that are offered on the dedicated virtual hosting service are offered on Redcentric's shared virtual hosting service. The main difference is that clients are utilised on Redcentric owned/deployed infrastructure, enabling the customer to take advantage of the benefits of a virtual environment without the initial infrastructure costs.

Streamline your business and running costs by consolidating your computing hardware. Virtualisation allows you to uncouple applications, desktops, servers and data from being dependent on any one physical device, maximising productivity, hardware utilisation rates and business continuity plans.

Experience & expertise

We're experts in designing, implementing and supporting a wide range of vendor products in the virtualisation space. We can give you advice that ensures that our solutions are perfectly tailored to your requirements and budget.

The key component parts of a virtualisation solution are:

Application virtualisation

This centralises the installation of user applications, so that they can be easily deployed and maintained across large groups of users spread in many locations. It enables Branch Office Connectivity and Remote and Mobile working solutions.

Desktop virtualisation

Also known as 'thin client computing' or VDI, this solution removes local desktop operating systems and centralises the delivery of them (as with applications only) for an entire user desktop - for example, Windows 7. A PC is not needed on the user desktop to run a Windows OS. It enables branch office connectivity and workforce mobility solutions.

Server virtualisation

Server virtualisation allows multiple virtual servers to run on one physical server simultaneously. Drastic physical server reduction and consolidation, high availability, disaster recovery and green IT solutions can be achieved.

Storage virtualisation

Storage virtualisation enables the delivery of virtual pools of data to servers and desktops, effectively removing wasted physical storage space. As the total amount of used physical storage increases, more disk space can be easily added without the need to move data or resize data volumes.

Desktop virtualisation

Virtualise the operating systems for your end user access devices and manage them centrally within the data centre.

Server virtualisation

Server virtualisation is the masking of server resources, including individual physical servers, processors, and operating systems, from server users

Application virtualisation

Redcentric's provision of services and solutions around application virtualisation encompass traditional application virtualisation technologies and extends to cater for virtualisation of key applications

User virtualisation

User virtualisation is a way of managing user-specific information independent of the desktop, and applying this information into any desktop on-demand.

Storage virtualisation

Storage virtualisation is the pooling of physical storage from potentially multiple network storage devices into what appears to be a single storage device
