Design your virtualization architecture office

Design your virtualization architecture office -

One of the first questions someone make desktop virtualization wants to answer is usually one of the following questions

• How many servers do I need?
• How many IOPS?
• How XenDesktop controllers do I need?

I saw him several times and have been asked these questions repeatedly. The typical answer is "It depends" (BTW I really hate this answer). The wrong answer is any number (You do not have enough information). A more accurate answer is "Let's get to X, where X is the number of servers" (Pretty much the same thing as "it depends", but we did not have to say. "It depends")

Thus, to start solving for X, we need to ask a wide range of issues around the use of user requirements, location, personalization, hypervisor, hardware specifications, etc. the list can be quite long if you want a realistic and accurate response. the problem with this approach, which is the same approach I've seen many people take is that

the number of servers, number of IOPS, the number of XenDesktop controllers are some LAST design decisions you need to answer. Before you can answer this, you must understand the parameters of the user, you need to understand how users will have access to the environment and you need to understand what forms the user's virtual desktop will take.

The proper way to make a virtual office design is to follow the 5-layer model

1. user layer: Focus on decisions that affect users directly: terminals, receivers, etc. must be done for each user group
2. access layer :. What types of authentication, encryption and bandwidth each user group require? Must be done for each user group
3. Bureau layer :. What is the user's virtual desktop look like? OS, applications, profiles, policies, printing, etc. must be done for each user group
4. Control layer :. Which and how infrastructure components are required (Access Gateway, StoreFront, controllers XenDesktop / XenApp, Provisioning Servers, etc). Must be done for each data center
5. hardware layer :. How physical hardware is needed, including number of servers, total storage requirements, the total needs of IOPS, the number of virtual machines, etc. Should be done for each data center.

When using the project accelerator, you see this model 5-layer shown in the architecture diagram.

When you look at the NEWLY Manual Virtual Desktop updated, you see the design phase following the same stream, as well as many different design decisions, you need to answer.

I invite you to take a look at both. And notice that the latest additions to the Virtual Desktop Manual go into more details for the most appropriate design decisions within these layers.

Stay tuned for more as we work on further updates to the manual.
