In this post I’ll be going through how I have configured GSLB for NetScaler Gateway in Azure, and the various elements required for this type of configuration. Firstly – I began by setting up the background infrastructure to demonstrate this test. Namely, 2x Active Directory DCs within two Azure Locations (Eastern US (EUS), and South Central US (SCUS)). These were […]

NetScaler, as I am sure you are aware, is a superbly powerful Application Delivery Controller. One of the most useful features is the use of Responder Policies/Actions, and Backup vServers to indicate that a service is down or to provide access to an alternative service for end users. Let’s say – you have a load balancer configured that balances two […]

I’ve been blogging a lot this year on the merits of Citrix Workspace Environment Management (WEM) and the various features it provides. Another feature is I/O Priority – which enables us to manage the priority of I/O operations for a specified process: To demonstrate this, I am going to run IOMeter (a storage testing tool – that consumes, but also […]

After testing out the excellent CPU and Memory management features in Citrix Workspace Environment Management (WEM), I wanted to blog about how processes can be controlled using the software. Prior to starting this test, I have a basic Citrix XenDesktop environment configured, a WEM environment configured, and the relevant group policies in place to support this. To prevent processes from […]

Atlantis provide a number of testing guides and videos on the USX Community Edition landing page – and also a testing […]

I’ve been doing some work recently around Citrix Provisioning Services, and this has prompted me to investigate what new features are available in version 7.11. One that stood out to me was the support for Microsoft’s Resilient File System (ReFS) on Windows Server 2016. This file system is interesting for those with virtualized environments due to the extra speed enhancements […]

Overview I’m a big fan of the VMware OS Optimization Tool and its capabilities, not only does it help to optimize VDI Environments through a range of settings and templates, it also helps optimize settings that otherwise would be complicated to control without a scripted or policy based method. I must confess I have been using this tool for some […]

After testing out the excellent CPU management features in Citrix Workspace Environment Management (WEM), I wanted to test out how well it handled applications that were particularly greedy with RAM consumption. To start – I have a single Windows Server 2012R2 Session Host, with 4GB of RAM, and a single vCPU, running on vSphere: Limitations for this VM have been […]

One of the great features in Citrix Workspace Environment Management (WEM) is the ability to intelligently manage CPU usage. This is especially important in a shared desktop scenario – where the actions of one user could ruin the experience for another. To test this I am going to demonstrate a user running SuperPI (a CPU stress testing tool) and how […]
Continue Reading →I recently needed to change the SQL Collation to allow for a System Center Configuration Manager install, but I forgot to do this when I built the SQL Server. To change this after installing SQL, run the following command: setup.exe /q /action=rebuilddatabase /instancename=mssqlserver /sapwd=yourpassword /sqlcollation=SQL_Latin1_General_CP1_CI_AS /sqlsysadminaccounts=domain\administrator Note: if you need to see the command output, remove the /q. Also – […]

Introduction Many XenApp administrators will remember the Zone Preference Failover features available in previous versions. For those unaware, this allows resources to be served from Hosts within a logical group (a Zone), unless a failure/maintenance condition exists, in which case resources are served from a Secondary Zone. Using Zones we can provide applications from a single Zone, with failover to […]
