A few weeks ago, I did a research with Leee Jeffries for GO‑EUC on NVMe memory tiering versus traditional swap in VMware ESXi. VMware ESXi Memory Management Reimagined: NVMe Tiering vs Traditional Swap | GO-EUC The article sparked some great discussions and there is an important caveat when it comes to vGPU desktops that I want to highlight. vGPU Desktops Always Need Full DRAM Here’s the thing that often trips people up: every VM with a vGPU requires all of its RAM to be rese

Measuring Real Latency — The Missing Piece in VDI Performance Latency isn’t just a number you pull from monitoring tools. It’s about the delay users feel, the gap between when they click and when something actually happens on their screen. In virtual desktop environments, traditional latency metrics (like server response times or network delays) only tell part of the story. Users interact with their device locally, so the real question is: how long does it take until their sc

You know, most VDI environments run like a well painted canvas. The default FSLogix GPO covers most users with smooth even strokes. They are happy users, their profiles load fast, and the picture looks just right. But then there are the VIPs, those special users with bold bright colors. The users with massive OST caches that need a bigger space, or the sales crew whose Teams data just keeps growing like a happy little forest. This is when the ObjectSpecific keys step in, like

On december 18, 2024, I had the honor to do a live webinar with Leee Jeffries. "Mastering the Multi-Layered EUC Environment: A Journey Through the Maze" We show how we test and validate the layers with Login VSI. Some of the technologies mentioned are Omnissa Horizon and Appvolumes, Liquit part of Recast Software, IGEL Technology and Microsoft EntraID Conditional Access... sounds like a challenge right!? In case you missed it, here is a link to the recording: Mastering the M

So… on December 19th of 2024, Omnissa released App Volumes 2412. One change I’m most thrilled about: MSI for Windows Endpoints AND and discovered: Physical Endpoint support! App Volumes now supports MSI-wrapped VHD packages, alongside traditional VHD and VMDK formats. This allows the App Volumes agent to operate independently within existing delivery infrastructures such as Workspace ONE UEM, Microsoft Intune, and Microsoft Configuration Manager. and with the parameters of th

Recently got involved in designing and building a new awesome blistering fast Omnissa Horizon environment for a hospital. This new environment is based on the latest Horizon ESB, DEM, AppVolumes, Windows 11 etc. And as many hospitals do, they use Imprivata OneSign. We ran into a bug. When logging in to the desktop (either Imprivata Client or Horizon client directly) we got confronted by the Imprivata GINA screen. Once again entering credentials and the desktop continues. Reco

A while ago I created a discission tree to explain/help customers and coworkers with a couple of the design choices possible with the FSLogix Office 365 and/or the Profile Containers. I thought to share this, hoping this will help others in their decision making! If you need any help, additional explanation, have any remarks or additions I should add, please let me know! First starting with some of the basics, if you don't need the basics just scroll down to use the chart! W

As you probably already know App-V was originally scheduled to end in January this year (2023). Recently Microsoft announced they pushed the EOL date to April 14th, 2026 so you have still have some air left. But you have to think about a new strategy to deliver the apps. A great alternative is VMware AppVolumes! Little is known you can also use this when you use Citrix Virtual Apps and Desktops. Even better you can use this with the new amazing AppVolumes on Demand feature!

Ran into a little bug yesterday while implementing VMware Horizon and Imprivata. Appliances rolled out, configured the site, policy's etc. etc. On the regular Windows endpoints this worked as expected. Login went fine, tabbed a badge, entering additional credentials if required by policy and the session would beautifully start, locking, roaming, smooth as silk.. Pushed the Imprivata agent to the Thin Clients (Dell Wyse based on Windows 10 IoT, although the brand does not matt

A while ago me and my friend and colleague JP Ruitenbeek were “flown in” to investigate performance issues at a customer. We found multiple issues but in this one we focus on a specific one: “The After-reboot jobs.” The Start: Lately a lot of complaints received the IT department of this customer about performance, latencies and login issues. The users were simply losing trust in the environment. Sum up some of the complaints: · Login times very high · Slown

A while ago I got asked by a customer how they can auto turn off the monitor when they move away from the workstation. These workstations are located on an Intensive Care unit so when they need to access these machines at night, they want the monitors "on time" limited to a minimum to not wake up the patient too much. First thought: Manually turning off these monitors with the power button? (Smile and wave. No, we can do better!) Second thought: Power settings and the monitor

Buffer Overflow: [a] condition at an interface under which more input can be placed into a buffer or data holding area than the capacity allocated, With al little creativity and bending we also see this in a VDI environment, I name this a User Overflow: [a] condition at an environment under which more users try to be placed into a pool than the capacity allocated, Of course with VMware Horizon you can make the pools dynamic in size but you will be limited by the available har

Let’s play around with the Citrix Hypervisor and Citrix Provisioning Services. It’s been a while since I used Citrix Hypervisor in a production or even in my lab environment so let’s see if we can still run this nested on a VMware ESXi 7 host and stream a virtual desktop on it😊 I tried log all my steps and create screenshots.. Remark that I all ready had a running Citrix environment in place (Delivery Controller, License server, Provisioning Server(s), Storefront, ADC etc.)
