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 that testing was complete, we moved onto the next version… Windows 10. An again, looking at the exact same parameters. First, we look at Microsoft Hyper-V 2012R2 Second, we look at Citrix XenServer 6.5 SP1 What do you notice? Between XenServer & Hyper-V… Not much … 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 High Server Scalability vs Optimized for WAN Windows 7 optimizations Each test was conducted utilizing the same, knowledge worker workload.   As you see, each test builds upon the previous test while only modifying a single parameter. As I’ve gone through the initial results, some … Continue reading XenDesktop 7.7 and Windows 7

You don’t need to be a rocket scientist to see the value in RAM Cache


A few years ago, we replaced all of our windows in our home (I’m talking about the panes of glass you look through, not the operating system). We, of course, talked with a few different companies who stopped by, went through their product portfolio and brought along samples. One demonstration stuck with me. The sales person, placed his sample window flat on the ground and stood on it, demonstrating the strength of the window. I immediately started thinking, “That was totally wicked” and “I wonder if it has ever shattered before”. As the practical part of my brain kicked in, … Continue reading You don’t need to be a rocket scientist to see the value in RAM Cache

PROOF[Video] – New XenDesktop and XenApp Storage Optimizations Does Improve the User Experience


I’ve written and seen numerous blogs/tweets about how great the new storage optimization feature is for XenApp and XenDesktop. I’ve read how this feature can reduce IOPS from an average of 15 IOPS per Windows 7 user down to 0.1 IOPS. I’ve read how this feature functions by creating a small RAM buffer within each VM. I’ve seen tweets showing crazy IOPS numbers on using standard, spinning disks. In fact, I’ve done some of this analysis and was completely blown away by the results. But who cares? Who cares if my IOPS are reduced by 99%? Unfortunately, unless you are … Continue reading PROOF[Video] – New XenDesktop and XenApp Storage Optimizations Does Improve the User Experience
