The clock is ticking for Windows XP. Mainstream Support has already ended and Microsoft will terminate Extended Supports on April 8th 2014. Only half of all enterprise IT organizations have completed their migration to Windows 7 and many will not be able to complete migrations with physical PCs before Microsoft ends all support. Desktop virtualization accelerates the process of migrating to Windows 7, while repurposing existing PCs to avoid costly desktop refresh cycles.
While VDI provides a fast and easy method to migrate to Windows 7, it also presents storage challenges. Windows 7 requires almost twice as many expensive SAN/NAS storage disks as Windows XP to deliver a virtual desktop user experience that is equal to physical PC. For a typical Windows 7 VDI deployment, storage accounts for 40-80% of the total cost of a VDI implementation, and is the number one cause of performance problems in VDI environments.
Atlantis ILIO software cuts VDI CAPEX costs by 50-75%, simplifies VDI deployments for Windows 7 migrations, and delivers a virtual desktop that is cheaper and faster than a physical PC. Atlantis ILIO Diskless VDI enables administrators to completely eliminate storage and SSDs for stateless Windows 7 deployments by using RAM as storage for virtual desktop images. For persistent virtual desktops, Atlantis ILIO optimizes virtual desktops to support 4-7 times more desktops on the same storage footprint, making VDI more affordable by both cutting the amount of storage needed per desktop and enabling the use of less expensive storage options.
Atlantis ILIO Diskless VDI is the only solution in the industry to enable stateless VDI deployments without the need for virtual desktop. SSDs, SAS and SATA drives are completely eliminated from VDI deployments, greatly reducing CAPEX and all storage-related OPEX costs including power, cooling and the cost of maintaining and repairing failed devices. In addition, without storage sizing, deploying stateless Windows 7 virtual desktops has never been so simple. Atlantis ILIO just uses local server RAM as storage for virtual desktops, delivering a better than PC user experience.
With Atlantis ILIO, virtual desktops use storage efficiently by consolidating duplicate information contained in virtual desktop images in real-time before they hit storage. This has the combined benefit of dramatically reducing the storage capacity and reducing the storage throughput required by up to 90%. By reducing data center storage and supporting infrastructure requirements and increasing the number of desktops per server, Atlantis ILIO can reduce VDI CAPEX by 50-75%.
Enterprise IT organizations considering application virtualization solutions, such as Citrix XenApp, Microsoft App-V, or VMware ThinApp for use in conjunction with VDI and Windows 7 migrations, face a dual challenge with both application performance and managing the workload of repackaging applications for deployment through application virtualization. When organizations are ready to implement application virtualization, Atlantis ILIO accelerates the delivery of both pre-cached and streamed application virtualization packages.
For some organizations, the pragmatic path to getting started with VDI is to deploy persistent virtual desktops, where each user gets their own unique virtual desktop image. This approach eliminates the need to implement additional VDI components such as OS streaming, application virtualization and profile virtualization. However, persistent desktops require 40-80GB of of expensive SAN/NAS storage per desktop, making them cost-prohibitive. Many customers that are on an aggressive timeline to complete a Windows 7 migration use Atlantis ILIO first to deploy persistent desktops with 90% less storage. This allows organizations to quickly and easily migrate to Windows 7 without changing the desktop management processes. Then, over time, IT organizations and make a smooth transition to stateless desktops using by using the automated deployment capabilities of Atlantis ILIO Diskless VDI to eliminate storage from the VDI implementation.
