Storage, Servers, and User Personalization in Desktop Virtualization
License Price: US$ 4,740.00


Failure to adequately predict capital costs is one of the biggest risks to the success of desktop virtualization. Storage and servers will collectively form a very large share of capital expenditure, and storage presents the greatest challenges in terms of assessing required capacity, and limiting costs.

Features and benefits
  • Advice on the use of so-called stateless desktops and personalization software to reduce management overheads snd lower storage consumption.
  • Advice on how to minimize the heavy storage traffic generated by desktop virtualization

  • Management and storage costs are significantly reduced by the use of stateless desktops, which are created on demand as near-clones of master images. However, for typical businesses, this approach only suits a minority of end users. Over-use of stateless desktops threatens end-user satisfaction, and so can stall virtualization projects.

Your key questions answered
  • What are the pitfalls of using so-called stateless desktops, and what are the benefits of end-user personalization software?
  • How many servers are required to host a given number of virtual desktops?
