RingCube vDesk Overview RingCube vDesk is a high-performance enterprise desktop virtualization solution that simplifies the creation, access and management of Windows desktops through Workspace Virtualization. The vDesk solution increases user productivity, lowers desktop management costs and improves desktop virtualization performance. Users can run their virtual desktop at the office or on unmanaged PCs – at home, or at a client site. When users start their vDesk workspace, it transforms any PC into their own familiar and personalized workspace

  3. 3. SOLUTION BRIEF VDI customers were forced to choose between two combination of linked clone and offline, forcing deployment methods: persistent desktop pools and customers to choose between mobility and storage non-persistent desktop pools. With persistent optimization. Because the master template to pools, a new VM is provisioned automatically upon linked clone relationship has various limitations, the first use and then users can customize their proposed implementation for user-installed desktops, install applications and create data, and application support and provisioning is to virtualize have those changes persist between sessions. With and stream all applications into the user’s VDI non-persistent pools, any changes made to the desktop. However, many applications cannot be desktop environment including installing virtualized using application containers. The second applications, personalized settings and user- generation of VDI requires that organizations make created data are removed at the end of the session compromises on scalability, application support and the VM is returned to the pool, often restricting and automated provisioning to eliminate the VDI use to very specific cases in enterprise problems of the first generation of VDI. deployments. Unlike VDI non-persistent pools, VDI With either the first or the second generation of persistent pools are desirable for most enterprise VDI, there is no way for a user to take their entire desktop virtualization cases, but the storage desktop offline to work at home or on a plane. With requirements can be cost-prohibitive. This is a generation of workers who have come to rely on because such a deployment requires each named laptops and expect mobility, VDI in its current form user’s VM image, including the 2 to 10GB of data for will continue to be limited to a specific segment of the virtual machine’s operating system to be stored enterprise users. for each user, whether or not the user is logged into the VDI environment. Furthermore, end-user VMs The vDesk VDI Solution must be stored on a Storage Area Network (SAN), which is a significant cost increase as compared to RingCube vDesk can be used with VDI: typical PC storage and even that of network attached storage (NAS). • Alternative: As a much lower cost alternative that has no upfront Second Generation of VDI infrastructure costs The second and latest generation of VDI • Complement: As a complement for user architectures attempts to eliminate barriers to segments that require offline mobility adoption of the first generation of VDI by • Enhancement: As an enhancement to integrating application virtualization, application reduce storage costs and provide streaming, roaming user profiles and “linked clone” personalization, mobility and deeper technology.

The “linked clone” approach to reducing storage utilization makes sense conceptually as it vDesk over the network offers a centralized virtual essentially allows a common master template and desktop alternative to VDI that delivers the small differential snapshots for each individual operational cost reductions, productivity, user’s customized desktop. However, enterprises provisioning and manageability benefits of VDI quickly realize that the caveats of second without the upfront server capital costs and long generation VDI include restrictions on updating the deployment times. With vDesk over the network, IT master template once linked clones are in place and organizations can achieve the centralization and scalability limitations of a few hundred users. Also, management they desire while using the second generation VDI does not support the computing power of the existing PCs, eliminating 3

(For more information, see the vDesk over the network Solution Brief) vDesk Alongside VDI: Satisfying Diverse User Using Gartner’s cost assumptions, the server capital Requirements cost alone for a 2,500 user HVD deployment is Many organizations have deployed VDI to a limited approximately $750,000 USD. For those customers subset of users such as task workers, outsourcers or who wish to avoid these types of upfront capital for disaster recovery. However, due to the mobility, costs associated with VDI deployments, vDesk personalization or management challenges of VDI, offers three additional deployment modes (PC, they have not been able to deliver a viable desktop Drive and Network).
