Machine Creation Services RAM Cache and XenServer IntelliCache


As I was discussing the storage optimization capabilities in the Machine Creation Services vs Provisioning Services debate, I mentioned the use of a XenServer RAM-based read cache. This can be misunderstood as XenServer IntelliCache (a mistake I'm sad to say I've made in the past). XenServer IntelliCache (released with XenServer 5.6 SP1) and XenServer RAM… Continue reading Machine Creation Services RAM Cache and XenServer IntelliCache

Sizing XenApp Windows 2012R2 Virtual Machines


I guess I'm not done yet. Last week, I posted the latest recommendations on sizing Windows 10 and Windows 7 virtual machines for a XenDesktop environment.  I received a few replies from people asking for any updates regarding Windows 2012R2. Unfortunately, when we discuss Windows 2012R2 and XenApp, the recommendations are not as straightforward as… Continue reading Sizing XenApp Windows 2012R2 Virtual Machines

Sizing Windows 10 and Windows 7 Virtual Machines


After reviewing all of the scalability tests we conducted over the past few months, I thought it was time to revisit the recommendations for sizing Windows 10 virtual machines.  I also reached out to Nick Rintalan to see if this is in line with what is currently being recommended for production environments (if you disagree,… Continue reading Sizing Windows 10 and Windows 7 Virtual Machines

XenDesktop 7.7 and Windows 10


The other day, I was able to share the latest single server density results when running Windows 7 on XenDesktop 7.7. We looked at a range of parameters like: PVS vs MCS PVS Disk Cache vs RAM Cache Citrix Policies: Very High Definition vs High Server Scalability vs Optimized for WAN Windows 7 optimizations Once… Continue reading XenDesktop 7.7 and Windows 10

XenDesktop 7.7 and Windows 7


We recently completed a massive round of testing looking at many of the different deployment configurations we can do with a Windows 7 desktop in XenDesktop 7.7. We wanted to look at how different factors might impact single server scalability. PVS vs MCS PVS Disk Cache vs RAM Cache Citrix Policies: Very High Definition vs… Continue reading XenDesktop 7.7 and Windows 7

Project Accelerator Question 1 – Technical Skillsets


One of the first questions that Project Accelerator asks you is what technical skillset you current have, with a list of about 20 different technologies.  Why do we care? Let's say you have App-V experience, then when you get to the application delivery portion, we will probably recommend you use App-V for a subset of… Continue reading Project Accelerator Question 1 – Technical Skillsets

RAM Smorgasbord


When I talk about virtual desktop specifications, we often break down our users into a few different categories (Light, Normal, Power, and Heavy). These categories correspond to the resources we allocate to the virtual desktop (assuming we are talking about the hosted VM-Based desktop model). This should be no surprise. This discussion directly relates to… Continue reading RAM Smorgasbord

XenDesktop Enterprise Design TechTalk Question & Answer


I recently did a TechTalk discussing XenDesktop Design topics. If you missed it, you can watch the recording. Unfortunately, I didn't have time to answer the questions during the webinar, but I've gone ahead and tried to answer them here. If you have more, please let me know. Thanks Daniel – Lead Architect Q: Can… Continue reading XenDesktop Enterprise Design TechTalk Question & Answer

A Virtual Desktop Storm Approaches


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… Continue reading A Virtual Desktop Storm Approaches
