8th Virtualization Expo in New York on Ulitzer Have you experienced this before? You need an application to help you with a project. You ask your manager if you can purchase the software and you get approval.  You go out and buy the software and install it onto your desktop and away you go to do your job.  This is a common situation, one I've done myself on many occasions. These applications make up the non-IT delivered application set of every organization, and it is a massive list.  This happens over and over again in every organization and in every department. So when you hear organizations say they have 10,000 or 20,000 applications, they are likely not exaggerating.  Out of that massive list, only 500-1,000 of those applications are IT-managed.  This brings about the main challenge with desktop virtualization, how do you deal with the non-IT delivered applicati...

Desktop Virtualization... The Right Way (Part 4)

One office with one type of desktop... Easy.  Hundreds of offices with any type and age of desktops... Difficult but not impossible. Most organizations find themselves in the difficult camp. A user's desktop can be completely different (in terms of hardware, resources, applications and configuration) than the person sitting next to them doing a similar job. As the environment includes users from different departments, in different offices, with different requirements it becomes clear that the understanding of the user topology for an organization is critical before one can create a...

Storms Can Kill Your Virtual Desktop

Rush hour. Something we all can relate to. Way back in time when I used to go to an office daily, I hated rush hour.  If I left home at a certain time, it would take me 45 minutes just to get to the office. But if I left just 15 minutes earlier, that same 45 minute trip would only take 15 minutes.  You might be asking yourself what this has to do with virtual desktops. Well, it’s all about managing a storm. I managed the rush hour storm by changing the time I left for work in the morning.  With virtual desktops, we need do something similar. If you don’t, you will encounter the f... (more)

Wasting Cache

It almost sounds like I'm talking about personal finances. You better plan your cache appropriately or you will run out. I'm not talking about money; I'm talking about system memory (although if you plan poorly we will quickly be talking about money). It comes down to this… system cache is a powerful feature allowing a server to service requests extremely fast because instead of accessing disks, blocks of data are retrieved from RAM. Provisioning services relies on fast access to the blocks within the disk image (vDisk) to stream to the target devices. The faster the requests ar... (more)
