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 →

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...

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 →

The New XenApp – Reducing IOPS to 1


As we all know, IOPS are the bane of any application and virtualization project. If you don't have enough, users will suffer. If you have too many, you probably spent too much money and your business will suffer. So we are always trying to find ways to more accurately estimate IOPS requirements as well as...

Sizing XenDesktop 7 App Edition VMs


In the Mobilizing Windows applications for 500 users design guide, we made the recommendation to allocate 8vCPUs for each virtual XenDesktop 7 App Edition host (formerly known as XenApp). Spreading this out across a server with two Intel Xeon E5-2690 @2.9GHz processors and 192 GB of RAM, we were yielding about 200 users per physical... Continue Reading →

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 →
