Why Consider Cisco UCS for Hosting your XenDesktop Cloud?
I have spent the last couple of weeks working with Microsoft 2008 R2 Hyper-V on the Cisco UCS platform. I am impressed at the capabilities. In fact, at the moment if you are planning to host a XenDesktop infrastructure in the cloud, I would recommend you consider the Cisco UCS platform.Admittedly, I was skeptic at first. When I thought of blade hardware, Cisco was ...
Finding a Better Way to Estimate IOPS for VDI
Planning storage is probably the most difficult part of architecting any VDI solution and estimating IOPS is probably the most difficult part of planning the storage. For a little background on some of the discussions I have had around this topic, see my Saving IOPS with Provisioning Services blog and the associated comments. Since posting that blog in August, I have had fielded multiple requests ...
PowerShell Scripts for XenDesktop Part 6
In my PowerShell Scripts for XenDesktop Part 2 back in April, I provided a script for copying the PVS write-cache drive and attaching them to virtual machines using the SCVMM library. Most write-cache drives are between 2GB and 4GB, which means if you had 1000 VMs with 4GB drives the SCVMM library would need to transfer 4TB worth of data. The script I provided ...

As promised in my Designing Scalable XenDesktop Farms webinar on 22 September, I have provided answers to the questions I did not have time to address. The full recorded webinar is available on Citrix TV or through the original URL above.Q: Are there any differences in scalability between hypervisors (Hyper-V, ESX, XS)? A: This is a very common question. I wish I could give you a ...
Using Scalability Reports to Size VDI Deployments
Lately, I have been getting questions around how to "size" a XenDesktop deployment. I have an AskTheArchitect webinar scheduled on How Scalability Impacts your XenDesktop Deployment that will help answer most of the common questions. However, with the recent release of the Hyper-V / Windows 7 / XenDesktop whitepaper I thought it would be a good time to go over just a few points on ...
How does kite fishing relate to XenDesktop?
I went kite fishing for the first time last week. Well, during this new adventure I got challenged by my teammates to relate kite fishing to XenDesktop, so this is my public reply to that challenge.If you haven't gone kite fishing, I'll try to give you a brief explanation from a layman's perspective. Kite fishing is on the ocean and you fly a kite ...
XenDesktop 4 on Windows 2008 R2 Hyper-V Scalability Report
Today marks the public release of the scalability report for XenDesktop 4 on Microsoft Windows 2008 R2 Hyper-V. I am excited about the release of this document, since it represents the culmination of six-months of work and a joint effort with Citrix, HP, and Microsoft. The co-branded report includes the following information:1. Testing methodology and test procedures for single-server and large-farm testing 2. Physical and logical architecture including ...
Secret to getting VirtualCenter to use an Enterprise CA SSL certificate
I have recently had a couple of acquaintances remark that they could not get communication between the XenDesktop DDC and VMWare VirtualCenter to work over HTTPS when using a Microsoft Enterprise CA. I had recently spent time on-site with a financial customer that required SSL communication and they had worked through it for over six weeks without any luck. Finally, they found an obscure reference ...
Saving IOPS with Provisioning Services
Sometimes the obvious is not quite as obvious to others as it is to you. Given my role as an architect I have spent countless hours looking at storage performance and the impact of it on Desktop Virtualization also known as VDI. It is my belief that storage performance is directly correlated with the user experience. Unfortunately, purchasing higher performing storage increases the cost of ...
PowerShell Scripts for XenDesktop Part 5
In an effort to finish publishing the PowerShell scripts I use for scalability testing, today's GenVMs.ps1 PowerShell script demonstrates how to create basic virtual machines on Microsoft Hyper-V 2008 R2 hosts through the SCVMM PowerShell interface. The exciting part about today's script is that when combined with the scripts I have previously released on this blog, it can be used to almost completely replace all ...
