GlassHouse and Atlantis Computing Publish Stateless Reference Architecture with Citrix XenDesktop to Simplify and Increase Performance of Desktop Virtualization

Barcelona (Citrix Synergy) – October 16, 2012 – Atlantis Computing, the leader in Virtual Desktop Infrastructure (VDI) storage and performance optimization solutions, today announced the release of the Citrix XenDesktop®  and Microsoft Hyper-V Reference Architecture with Atlantis ILIO Diskless VDI™ storage optimization software that was designed and tested in partnership with GlassHouse Technologies.  The joint reference architecture simplifies Citrix XenDesktop deployments, improves the user experience and cuts the CAPEX cost per desktop to $195 per desktop by using only local server RAM as primary storage for virtual desktops.

“Typically VDI deployments force customers to compromise on either the cost per desktop or the user experience, an archaic choice for something that is supposed to be a technological step forward,” said Jay Seaton, CMO, GlassHouse.  “When we design VDI reference architectures, the goal with our clients is to balance the cost per desktop, improve the user experience and reduce the operational overhead to maintain and scale the VDI infrastructure. This stateless reference architecture drives down the cost per desktop by eliminating storage, and the I/O performance using local server RAM results in a better-than-physical-user experience, and enables deployments that scale using only servers and software.”  

Reference Architecture Highlights:

  • Storage-less – Citrix XenDesktop virtual desktop images are stored using local server RAM, eliminating the need for traditional storage (SAN/NAS, or SSDs/Flash).
  • CAPEX Cost  – $195 per desktop including server hardware and Atlantis ILIO
  • Storage Optimization – Atlantis ILIO Diskless VDI reduced the amount of RAM used as storage for per Citrix XenDesktop virtual desktop to 129MB. 
  • Density – The reference architecture supported 140 virtual desktops per server.
  • Performance – The architecture achieved better-than-PC performance with: 
    • Boot Time – 16 seconds per desktop with 6 minutes to boot 140 desktops.
    • User Experience – The Login VSI performance benchmark recorded one of the best test results ever published with a baseline of 0.9 seconds response time.

“As customers begin their desktop transformation, storage is often the key challenge to overcome to achieve successful deployments both from a cost and user experience perspective,” said Rana Kanaan, vice president, product management, Desktops and Apps, Citrix. “The ability to use RAM as storage for virtual desktops with Atlantis ILIO Diskless VDI is truly innovative.  This reference architecture provides a blueprint showing customers how they can take advantage of this great technology to lower their cost per desktop, simplify their deployment and deliver an outstanding user experience.” 

Atlantis ILIO Diskless VDI is the only storage optimization software that eliminates storage from Citrix XenDesktop stateless VDI deployments. Citrix XenDesktop can now be deployed to thousands of users in a matter of a few hours without the cost, complexity and risks of installing and managing storage. Atlantis ILIO delivers a user experience that is much faster than a physical PC at a cost of $195 per desktop.

“Removing storage from VDI dramatically simplifies the entire deployment, eliminates project risks, and makes VDI easier to manage at scale” said Bernard Harguindeguy, president and CEO, Atlantis Computing.  “The combination of Citrix XenDesktop and Atlantis ILIO Diskless VDI enables the deployment of thousands of desktops in a matter of a few hours.  It is invaluable to IT teams looking to deploy virtual desktops quickly and successfuly.”

GlassHouse used the vendor independent benchmarking tool Login Virtual Session Indexer (Login VSI) to objectively test the reference architecture scalability and performance. Both leading IT-analysts and IT-vendors recognize and recommend Login VSI as the de-facto industry standard benchmarking tool for SBC and VDI. Atlantis Computing has recently been awarded the ‘Tested with Login VSI’ award in recognition for their proven commitment towards testing and securing the optimal performance, scalability and reliability of their Atlantis ILIO VDI storage and performance optimization software.
