VDI

This section covers and discusses information about various different VDI (Virtual Desktop Infrastructures) and technologies. This is not limited to just VMWare or Citrix. VDI is a subject of Desktop Strategies, and should be looked at in that fashion -- then it won't matter what the HW for the desktop is. That is the goal anyway -- to remove our reliance and tie to physical devices.

I'm Back! Thanks to Covid19

I am back online. I have not focused on my technology website. A couple of reasons for this, too much work and too little time. Second, it has not been a priority. My site was infected with a security vulnerability which required some code rewrites and updates. These have all been addressed and I'm back online.
In the coming weeks I'll be adding content regarding some of the last projects centering on Horizon Workspace One, Citrix Cloud, AWS, and Azure.

Thick Disk v. Thin Disk -- "It Depends!"

It is surprising how often this scenario comes up, and I get asked the question, "Should we thin-provision or thick-provision our VM's?" My answer is almost always the same, "it depends." Today, I have the same answer, but for very different reasons from in the past. In the past, my answer was based on performance-related issues and saving expensive disk space. These are still very, valid concerns, however, now I answer based on risk. In recent days have been working with three different clients that have all experienced outages related to thin-disk provisioning.

Windows 7 x64 with VDI. Why do it?

Here is the spoiler -- don't do Windows 7 x64 for VDI.
Now let's talk about why. First, I'm going to give credit to Brian Madden's Blog, he mentions this also, and he is exactly correct. Windows 7 x64 uses around 200MB more memory than the x86 version. If you multiply this by the number of VDI users, it adds up quickly. (1000 desktops x 200MB equals 2 TB more memory). For a project I'm working on this equated to a requirement for 8 more servers because of x64.

Citrix Receiver Versions

As a Citix consultant I spend the vast part of my day working with VDI in one form or another and on one device or another. I especially like my iPad, but I digress. Recently, I was tasked with looking at why some functionality worked for some people and it wasn't present for others. Everyone was supposed to be using the same version. However, discovery revealed that this was not the case and there were different versions. What are the versions?

Optimizing Windows 7 for VDI

It amazes me that we are still talking about how to deploy Windows 7 and that XP is still a mainstream OS, and likely will be until we get closer to 2014 when XP support ends. I find Windows 7 to be one of the best versions of Windows. Almost enough to get me to switch from Linux, almost. That said, I do a lot of VMware View work and my VDI clients ask what changes I make to speed up the VDI desktop.

Optimizing Windows XP for VDI

It is important to optimize the desktop for your VDI environment, this is true if your environment is Citrix XenDesktop or VMWare View. This document will outline some of the key changes that need to be made with your desktop. If this is to be your template give it a meaning full generic name such as "xp-template"
