Virtual Desktop Infrastructure (VDI) storage and performance optimization solutions provider, Atlantis Computing, has announced the release of Atlantis ILIO for Citrix XenApp.

According to the company in its prepared statement,  ILIO is designed to address the challenges associated with virtualizing Citrix XenApp deployments on VMware vSphere by reducing provisioning time, improving the user experience and cutting the amount of storage required by up to 90 percent when running Citrix XenApp in the virtual datacenter.

"Atlantis ILIO for Citrix XenApp is particularly critical to customers planning to virtualize XenApp 6.5 with Windows Server 2008 R2," said Atlantis Computing.

"There is a massive install base of customers on Citrix XenApp 4.5 with Windows Server 2003 that must move to Citrix XenApp 6.5 with Server 2008 R2 by March 2013," said Vincent Branger, Virtualization Expert and Consultant, Infralys. "When customers migrate to XenApp 6.5, the majority will virtualize Windows Server 2008 R2 to take advantage of the manageability and consolidation benefits of server virtualization. However, the combination of virtualizing XenApp, upgrading to Windows Server 2008 and shared storage introduces performance issues with provisioning, boot time and application response time for IO bound applications."

As XenApp customers migrate to Windows Server 2008, they want to virtualize their XenApp servers to take advantage of server consolidation and improve their manageability. However, the combination of virtualizing XenApp and moving to Windows Server 2008 requires a significant increase in the amount of shared storage needed to avoid performance issues.

"Both VDI and Citrix XenApp/RDS follow patterns of approximately 80-90% write activity vs. read activity during steady state. This means that the enhanced write capability delivered by Atlantis ILIO is extremely important to the scalability of the Citrix XenApp & RDS/TS platform," said Shawn Bass, Citrix CTP and Microsoft MVP. "Deploying RDS/XenApp workloads behind Atlantis ILIO can reduce storage requirements, improve provisioning and boot time and improve scalability."

Virtualizing XenApp causes a storage bottleneck that increases provisioning times, extends boot times and can reduce the number of XenApp sessions per server. To address the storage and performance barriers, Atlantis ILIO for Citrix XenApp continuously optimizes the storage traffic of the virtualized Windows Server throughout the daily cycle of re-provisioning, boot up and logon.

"As we deployed Atlantis ILIO for VDI to help optimize Citrix XenDesktop deployments, we were continually asked by customers about helping them with their Citrix XenApp deployments," said Bernard Harguindeguy, CEO of Atlantis Computing. "The Atlantis ILIO optimization of XenApp helps customers overcome the storage challenges of migrating XenApp to a virtualized datacenter, makes it possible to provision and refresh XenApp servers on-demand, and improves the user experience."
