Dataman Virtual Desktops Solution

  1. 1. Virtual Desktops – The Dataman Approach The growth of enterprise applications and the Sun Ray requirements of desktops to run these applications on, A Sun Ray is an UltraThin Client. Where normal thin have led to ever increasing demands in compute power clients still run a small operating system and require a on the desktop. With increase in compute power we see processor to run applications on (maintenance!), the Sun an increase in heat production, required cooling and Ray runs only enough firmware on a very small noise levels, which all are bad for a productive processor to connect to the central Sun Ray Server, environment both in human aspects and in cost- identify itself and receive screen-information for the user. efficiency. Traditionally solutions have been sought in use of thin- clients and energy efficient desktop PCs. However, these have the disadvantage of not allowing personnel to perform the kind of tasks which are necessary for proper operation on more demanding environments, resulting in hybrid environments which are more difficult to manage. Sun Ray 2 UltraThin Client A centralized Sun Ray Server services the various UltraThin Clients that are placed in the network. The Sun Ray Server can display Solaris, Linux or Windows. The Sun Ray Client uses 4 Watts of power as opposed to the 200 Watts for an average PC desktop. With efficient infrastructure power- and cooling requirements can be reduced by as much as 50% or more. There are no moving parts inside the Sun Ray Client. Sun Ray makes use of smart cards which uniquely An ideal solution would be an extremely low power thin identify users and connect the user to his or her desktop. client that allows desktop use as well as system A special feature of Sun Ray is hot desking. This allows administrator level installation and configuration of the user to take the desktop to any Sun Ray in the environments, yet at the same time requires zero network and to continue work there. desktop maintenance and centralizes and optimizes all administrative tasks for the various corporate VMware environments. In most enterprises the use of Windows is ubiquitous so display of windows desktops is required to ensure user In 2006 Dataman developed this concept based on Sun productivity. Microsystems® Sun Ray™ technology in combination with VMware® ESX™ as hosting area for virtual Because Sun Ray clients have no CPU and no platforms. Use of SAN technology and dedicated Sun Operating System and actually only show screen Ray systems allows hundreds of simultaneous users information which is delivered through the Sun Ray with various desktops to be operated and managed on a Server, it is necessary to have a platform which delivers single, centralized platform. the required Windows Desktops.

  2. 2. Use of VMware allows the creation of groups of user templates that facilitate instant creation of standard or specialized desktops for specific users. The centralized nature of the solution in combination with datacenter facilities creates a secure, high available, fast and efficient environment for corporate users. Use of SAN technology for VMware creates a centralized storage solution which holds both user and corporate data and which can easily be backed up to tape through traditional, proven tape solutions. In addition the centralized SAN for the desktops provide a high speed disk for loading of the operating systems or What are the implications? applications on the desktop. First of all the user experience will remain largely VMware also creates a universal hardware platform identical. Security is enhanced through use of which means that all operating systems will run on the smartcards and centralized storage of data. exact same hardware platform, which reduces the amount of work involved in finding proper drivers for new The initial investment in a Sun Ray solution will be as chipsets in new desktop PCs. high as or higher than a traditional desktop solution. This varies per implementation. Gains will become visible in: - ease of operation of the environment - reduced time to roll-out - flexible use of desktops - hot-desking facilities - reduced down-time of users due to PC failure - reduced power costs (4 W versus 200 W) - reduced costs in cooling - increased security and data-integrity - increased productivity through less sound pollution, Sun Rays have no moving parts - long life of ultra thin clients, typically five years or more - easy roll-out of desktops for new employees - smaller real-estate footprint versus traditional desktops - Service Level Agreement uptime for desktops can match The total amount of work required to manage the professional datacenter uptimes. desktops in a VMware environment is drastically - Centralized patch and upgrade management reduces reduced, the environment is more flexible and the time network loads; upgrades are done within the SAN. to roll out new desktops is significantly shorter. - Current networking investments can be extended as the Sun Ray requires less than 10 Mbit/s to function at full New Architecture speed. - These gains can be extended over the WAN to By combining VMware for centralized desktops and by employee’s homes. using Sun Rays and the Sun Ray Server Windows Connector the environment becomes a standardized, The typical ROI lies between 12 to 18 months, centralized solution with zero maintenance at the depending on the suitability of migration to the Sun Ray workplace. platform for various users. One great advantage to the solution is that most of the central infrastructure can remain in place. There is no change in user experience for the Desktops; there is only an expansion of the central environment.
