PVS Resource Usage Part 4
- Details
Introduction
In part 3 of the article series we started looking at boot(storm) scenarios. I described the four scenarios and the environment. Also the results of the first two scenario were discussed. In this last part I will continue with the remaining boot(storm) scenarios and will compare the results of the boot scenarios with the Citrix theory.
PVS Resource Usage Part 3
- Details
In this article series I will go into detail about resource usage of PVS servers. In the first part I described the theory values Citrix is using/advising for the components CPU, Memory, Disk and Network. The article series continued with taking a look at the real life resource usage of PVS servers. In this part we will take a look at resource usage of the PVS servers during boot(storm) scenarios.
PVS Resource Usage Part 2
- Details
In this article series I will go into detail about resource usage of PVS servers. In the first part I described the theory values Citrix is using/advising for the components CPU, Memory, Disk and Network. Also physical versus virtual is touched briefly. The article series will continue with taking a look at the real life resource usage of PVS servers. In this part we will take a look at the resource usage during daily operations.
Accessing the old environment from XenApp/XenDesktop 7.x
- Details
In almost every current XenDesktop/XenApp project for a specific period some applications are not available on the new platform, which are required by a group of users. A decision could be to let those workers do their work on the current/old platform. However most organizations don’t want that because the users don’t have access to new technologies of versions of other applications. In most cased the customer is looking for a way to offer access to those applications within the new platform. In this article I described the possible access methods to those applications running on a legacy environment, followed by the technical options to provide the access (including the advantages and disadvantages).

PVS Resource Usage Part 1
- Details
Some people are saying that PVS is complex. I personally don’t think that PVS is complex looking from an infrastructure endpoint, but it can be complex to understand the concept of PVS and the new way of working. When people get that part, the complexity is not a bottleneck anymore. But when people understand the way of working understand new questions are often raised. How many bandwidth does this solution requires, which hardware resources requires these PVS server to serve their role. In this article series I’m diving into this topic. First I will discuss the theory of the resource usage by Citrix, followed by real life figures. The real life figures are divided in two parts: daily usage and boot (storm) usage. As just mentioned we are starting with the theory.
Advanced Citrix Load Balancing Scenarios with Worker Groups
- Details
In the article Citrix Load Balancing Policies explained I described where and how to use Citrix Load Balancing. One of the most used scenarios is redirecting user to a specific group of servers defined in a Worker Group. At some customers we were also using Citrix Load Balancing for that use case, but during those projects some additional concepts were introduced and we should get it working with the already defined Load Balancing Policies. In this article I’m going to describe the scenarios and how that can be accomplished with the defined Load Balancing policies.

The case of the magic unknown Citrix Provisioning Services feature
- Details
On one of my projects we are using Citrix Provisioning Services (PVS) for our XenApp 6.5 environment. At this project several teams are responsible for the different stages in the infrastructure (DTAP, Development, Test, Acceptance and Production).
After a while one of the guys of the test environment came to me asking me how and why we are using fixed IP addresses within the PVS image. I told me that this could not be the case as the design was written based on a DHCP based IP address and I was pretty sure that none of this colleagues in test has the knowledge available to configure fixed IP addresses within the possibilities PVS is offering. In this article I will start describing which documented options are available within PVS to use a fixes IP address within the PVS image, followed by showing the magic unknown feature in Citrix Provisioning Service the test colleague encountered accidently.

Customer Case: Everything on Top Discussions Part 4
- Details
In the first part article I explained the current infrastructure and the requirements the organization had for the new environment, while I started describing the project using the biggest discussion points in the second article and third article. In this fourth and last article I will describe the latest discussion points (SSL Gateway and Outbound Connections) and the experiences so far.

Customer Case: Everything on Top Discussions Part 3
- Details
In the first part article I explained the current infrastructure and the requirements the organization had for the new environment, while I started describing the project using the biggest discussion points in the second article. In this third article I will continue describing the project using the discussion points Global Load Balancer and Server Installation/Configuration.

Customer Case: Everything on Top Discussions Part 2
- Details
In the first part article I explained the current infrastructure and the requirements the organization had for the new environment. Instead of telling a you a perfect story and successful the project was I will describe where we went through by describing our biggest discussion points and the effect on the project.
