Virtualization FAQ

  1. My business needs a scalable solution that is reactive to demand – can a virtualized environment cope with this?
    Yes, virtualization allows you to scale up or down as demand changes with just a few mouse clicks.

  2. How does virtualisation reduce data centre costs?
    Virtualization lets you consolidate infrastructure and hardware by replacing physical servers with virtual machines and by combining applications on virtual servers – saving space, energy costs and hardware costs. Virtualization also makes the most out of the resources you already have, increasing server utilization rates from as little as 5 percent to as much as 80 percent.

  3. How about Disaster Recovery?
    Virtualization software makes it easy to duplicate virtual environments as well as create backups so effective disaster recovery planning is much more straight-forward.

  4. Are there benefits relating to testing and evaluation?
    Virtualization allows for rapid server provisioning, which can be done with virtual machines created from snapshots of previous environments. So set up and breakdown of test environments is quick and easy.

  5. Are virtual environments secure?
    They are as secure as your existing environment but virtualization allows you to easily isolate applications and give them granular access rights.

  6. We have geographically dispersed locations – can we link them in a virtualised environment?
    Virtualization lets you pool computing and storage resources and lets users across the enterprise access them irrespective of whether the resources and the users are at the same location.

  7. How many virtual machines can run per processor?
    The number of virtual machines that can be hosted by a server depends on the power of the physical box (the memory, processor speed etc) and the resource demands of the applications on the virtual server. A higher box power and lower application resource demand mean a greater number of virtual machines can be hosted. Conversely, lower box power and higher application resource demand mean fewer virtual machines per physical server.

  8. How are application upgrades and patches deployed in a virtualised environment?
    Virtualization allows you to push out software updates, OS patching and new software installations from a central server to virtual desktops.

  9. What operating systems do virtual servers run on?
    This will depend on the individual virtualization solution, but almost all virtual systems run on Windows, Unix, or Linux operating systems.

  10. Is virtualization beneficial for every business?
    Not necessarily. Although there are nearly always benefits, the costs can out-weigh these in certain circumstances when staff training, additional management resources, upgraded hardware and various other considerations are taken into account. PT Solutions IT Health Check can assess your current infrastructure and advise on the cost-benefit balance in your organisation.
