On April 9, VMware announced Horizon 6, which includes multiple feature updates to the Horizon suite. The biggest item to note is the release of Horizon View 6, which will now offer publishing applications accessible via PCoIP. As noted in the announcement, VMware is going right at Citrix, specifically with the various issues involved with upgrading Citrix XenApp 6.5 to 7.5. Citrix XenApp 7.5 requires a completely new build in parallel to the existing Citrix XenApp 6.5 environment. As of now there is no... read more.

As many Citrix customers already know, Web Interface 5.4 is the last version that Citrix will be releasing. Going forward, Citrix will have updates only for StoreFront. There has been an increasing level of debate when architecting a Citrix XenApp/XenDesktop solution. Web Interface has been around for approximately 10+ years, first released as NFuse, and as a means of accessing published applications both internally and externally. Citrix released Secure Gateway to encrypt the Citrix ICA traffic as an ad... read more.

In this blog I review how to set up Citrix XenDesktop with persistent virtual desktops in a DR scenario. I have written in the past regarding why some companies are forced to go with persistent virtual desktops as opposed to non-persistent desktops. With Citrix XenDesktop, sites are used and a single site can’t span geographic datacenters. For a production/DR setup you would require two XenDesktop sites, both managed independently. Unfortunately Citrix doesn’t offer any type of site failover and/or hooks... read more.

In Citrix Provisioning Services, there are two options for creating virtual disks: fixed and dynamic. When both of these disks are created, you set the maximum size up front that will appear in the guest virtual machine. The difference between them is the amount of space allocated up front. With a fixed disk, all of the space is allocated up front. When a dynamic disk is created, only a small amount of space is created up front. The size of the dynamic disk increases over time as you begin to use more space... read more.

With the impending end of life (EOL) for Windows XP SP3 (April, 2014), many customers are looking for ways to have applications run on Windows 7. The majority of applications that customers utilize today have Windows 7 compatible versions. Although in some cases, using the Windows 7 compatible version requires upgrades to backend infrastructure (Oracle, SQL, etc.) servers. For one of our customers, one application required a multi-million dollar upgrade just to run the Windows 7 version of the client. Cu... read more.

Along with the new products and acquisitions announced at VMworld Barcelona this past week, VMware announced new features to be included in Horizon View 5.3. Two features I want to call out specifically are: 3D Graphics Support for Windows Server 2008 for virtual desktops 3D Graphics support: VMware is now supporting the NVIDIA Grid cards making VMware Horizon View a good use case for AutoCAD groups or any group of users that requires a pass-through or virtualized GPU. This makes sense as Citrix X... read more.

One of the key design considerations when architecting a VDI solution is the use of persistent desktops vs. non-persistent desktops. My colleague, Chaim Landau, wrote a previous blog ( around persistent/non-persistent desktops focused on the use of Citrix personal vDisks (PVD). The focus of this blog is more around storage and best practices. Persistent Desktop Pros: More or less the same as the physical desktop, but obviously virtual Abi... read more.
