As IT administrators, we are often asked how we can be more proactive to reduce exposure to issues that may arise. In Citrix XenApp and XenDesktop 7.18, a new feature was introduced to help identify issues from user locations to the Citrix environment hosting the applications and desktops. This feature, Application Probing, has a few requirements, but is not too difficult to set up and can provide immediate value. Application Probing requires the following: Citrix XenApp / XenDesktop 7.18 or newer runni... read more.

Part 1: Adding the Timeline Visualization Why a Timeline? One important metric when delivering user desktops is the amount of time the user has to wait for the desktop to launch. It’s hard to ensure user acceptance of the delivered environment if they find it slow before their desktop even becomes available.

Throughout my years of IT consulting, patching servers and desktops has been a sore subject with customers. It’s always been something that is required, but in many cases not performed. The benefits of patching in a timely manner include feature enhancements, bug fixes, and of course security updates. But for many of our customers, patching is time-consuming and resource-intensive, and gets in the way of IT teams focusing on more strategic and tactical matters. As a result, patches aren’t maint... read more.

As part of a high availability implementation for a customer project, I needed to duplicate vDisks from one datacenter to another. This customer had vSphere configured where a cluster represented a datacenter. For testing purposes, I first copied a vDisk and the virtual machine template to the second datacenter. After configuring PVS with the new vDisk, in the new cluster, I launched the PVS wizard to create a new virtual machine using the copied template. However, on boot up, the servers blue screened with... read more.

During a project building a XenDesktop 7.x environment, the customer requested that I use SQL replication between three servers instead of the SQL Always On feature for high availability. For this particular project, the Citrix environment was not a critical component of the business and the customer only had SQL 2016 Standard licenses. In order to use the database of one of the replicated servers during a failure of the main server, a DNS name would be used when creating the Citrix databases. During this... read more.

Most disk array controllers on servers include a piece of RAM that can be utilized to temporarily buffer data being written to or read from disk. Since access to RAM is significantly faster than disk access, this cache can enhance overall server performance. With respect to Citrix XenApp servers, improved server performance can lead to much higher user density per server. Unlike writing to disk, writing to RAM is volatile, which means it needs power to maintain the stored information. Array controllers u... read more.
