The City of Caceres hosted last week the 25th RedIRIS Technical Conference, involving more than 400 ICT experts from different institutions. As usual, the Technical Conference sessions were preceded by Working Groups, where the objective was to share the experiences of different universities, research centres and other institutions.
The DOCENCIA-NET Working Group dealt with Virtual Ecosystems and two sessions focused on UDS Enterprise software.
The formula to get rid of proprietary systems to deploy a desktop virtualization platform, the new operating systems supported by UDS Enterprise and OpenSUSE 13.2 in KDE or Gnome desktops have been the most interesting topics for our readers during the last two weeks.
If you didn’t have the chance to read these posts, here you are the links, so don’t miss the most outstanding information according to our followers:
How to deploy a fully Open Source virtual platform
The data, documents and application configurations of the user are saved in the user profile when the user is working with a Windows desktop. Different information is stored in the user profile, such as:
-Desktop appearance, desktop background, themes, screen configuration, use of Aero in Windows 7, etc.
-Application configuration, navigator preferences, tool bars, office software tool configurations, etc.
-Documents. These documents are stored in the “My documents” folder of the user profile.
In some cases, when analyzing the storage needs for a VDI platform we look at saving disk space when using template-based or non-persistent desktops. Nevertheless, it is necessary to bear in mind that all the I/O operations on disc in a standard job platform are made on local discs located in each post.
In a VDI environment, all these I/O operations take place concurrently on shared storage. Tasks such as updates of OS patches, antivirus, user logins scans… produce a large amount of concurrent I/O operations that are referred to as “storms”. These storms produce a deterioration in the performance of the storage because these I/O operations are accumulated in queues and this, obviously, causes an irregular performance of the virtual desktops.
Very shortly after Citrix announced its Linux technologies for vApp and virtual desktops in XenDesktop and XenApp, VMware reported that Horizon View will support Linux in 2015. And why these firms have decided to take this step? It is very simple. Companies using Linux and Windows would find a VMware and Citrix unified virtualization tool very useful.
In this way, they would no longer maintain two virtualization platforms, two support teams, two protocols, two clients and two different environments. They could manage everything centrally.
