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 Cache (released with XenServer 6.5) are two different capabilities of XenServer, both of which tries to reduce the  IO impact on shared storage. Let’s walk through different deployment scenarios with Machine Creation Services in XenApp and XenDesktop 7.9. Scenario 1: Shared Storage on any Hypervisor … Continue reading Machine Creation Services RAM Cache and XenServer IntelliCache

PVS vs. MCS – Part 3: Storage Optimization


This is part of a series comparing Provisioning Services and Machine Creation Services Part 1: Resource Delivery Options Part 2: Scalability Part 3: Storage Optimization Part 4: Deployment Part 5: On-going Maintenance Part 6: Architecture Part 7: Summary   For years, storage optimization has been one of the major strengths of Provisioning Services. With PVS, we can do the following: Optimized temporary storage allocation: PVS allows us to store the read-only master image on local or shared storage. We can also decide where to place the temporary, write disk, which could be on the PVS server’s local storage, the hypervisor … Continue reading PVS vs. MCS – Part 3: Storage Optimization

PVS vs MCS – Part 2: Scalability


This is part of a series comparing Provisioning Services and Machine Creation Services Part 1: Resource Delivery Options Part 2: Scalability Part 3: Storage Optimization Part 4: Deployment Part 5: On-going Maintenance Part 6: Architecture Part 7: Summary In Part 1 of the PVS vs MCS debate, we saw Provisioning Services bridges the gap between the physical and virtual world Machine Creation Services bridges the gap between the on-premises and cloud world Let’s continue digging into the PVS vs MCS debate and focus on scalability. Scalability plays a big role in the solution. If one solution only scales to 500 … Continue reading PVS vs MCS – Part 2: Scalability

PVS vs MCS – Part 1: Resource Delivery Options


This is part of a series comparing Provisioning Services and Machine Creation Services Part 1: Resource Delivery Options Part 2: Scalability Part 3: Storage Optimization Part 4: Deployment Part 5: On-going Maintenance Part 6: Architecture Part 7: Summary Five years ago, Citrix released Machine Creation Services.  As a way to help admins decide between Provisioning Services and Machine Creation Services, I created a decision tree, breaking the decision across multiple requirements. A lot has changed. Provisioning Services changed. Machine Creation Services changed. You know what didn’t change?  Homer, Marge, Bart, Lisa and Maggie Simpson. You know what else hasn’t changed? … Continue reading PVS vs MCS – Part 1: Resource Delivery Options

XenDesktop 7.7: Windows 7 vs Windows 10


Everyone loves a good battle The Simpsons vs Family Guy Kirk vs Picard Star Wars vs Star Trek Microsoft vs Apple And now, we have one more, which will be a big debate for 2016… Windows 7 vs Windows 10 Over the last couple of weeks, I’ve been sharing some of our single server scalability testing results for Windows 7 and Windows 10 across Microsoft Hyper-V and Citrix XenServer utilizing XenDesktop 7.7. Each test compared a different image management model, Citrix policy and operating system optimization configuration. What was more interesting, and worrisome, was when we started comparing the same … Continue reading XenDesktop 7.7: Windows 7 vs Windows 10

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
