Virtualisation FAQ's


  • What is a virtual computer?

    A virtual computer is just a computer that is running on shared hardware, see our explanation.  A virtual computer operates and behaves like a computer; you will not see any difference in use.

  • Why have virtual computers?

    Because a physical computer shares its hardware across several virtual computers you do not need to buy as many physical computers.  The saving is in having fewer hardware computers to buy and run, giving lower hardware, maintenance and power costs.


    Hardware will limit the number of virtual computers on one machine, but people generally find 5-10 virtual machines is normal.

  • What is a hypervisor?

    The hypervisor is the software that provides and manages computing resources to virtual machines.  There are several different ones, the most well-known are, VM Ware, Microsoft Hyper V, Citrix XEN and KVM Scale Computing.

  • What is a storage cluster?

    A storage cluster reliably provides data for information and systems from a pool of machines.  The storage cluster is reliable because any single component can fail and still enable the cluster to provide the data as required.  In addition the storage pool can be simply increased in size by adding new machines, so you can grow your storage as you need it.  Earlier Storage Area Networks (SANs) are notoriously complicated and expensive to set up and operate.

  • What is the benefit of a storage cluster?

    There are many; the key benefits are reliability and simplicity, particularly when used in conjunction with virtual machines.  You remove your reliance on single pieces of hardware and so improve overall reliability.   Overall you will save capital and running costs in having fewer computers and operational costs because they are simpler to control and manage.


    One of the biggest technical benefits is improved flexibility and the ability to change your systems, this may be difficult to justify financially but will make life easier where there is uncertainty or you have potential changes that you need to cater for.

  • Are we ready for a Virtual machines and Storage Cluster

    You should look at both virtual machines and storage cluster if you are considering adding to or changing your computing infrastructure, particularly the HC3 solution.


    You should take a good look if

    1. You are retiring old hardware or upgrading your systems

    2. Need to grow your systems

    3. Want to consolidate hardware and reduce the space used

    4. Simplify the management of your systems

    5. Improve reliability, reduce the chance of failure

    6. Increase flexibility and save cost

    7. Sleep better at night.

  • What is the business case?

    We believe that people should look at their options and choose the right solution for them.  We like to help people make the business case as the costs of new equipment and changes are often more than just the equipment.

  • Are special skills needed?

    Some new skills are needed but these are relatively easily learned.  All the old skills are still used, although the opportunity to consolidate and simplify will make life easier.

  • Can I see a useful demonstration?

    Yes the virtualisation approach can be quickly demonstrated (request a demo); there are also many short videos that describe how things work.

  • What support is there?

    We support all of our customers, both ourselves and through the specialist suppliers.  We take ownership of the problem through to resolution, so you should never feel stranded between suppliers.
