user-installed applications or data. These features, combined with the network optimizations, create a number of use cases: Single Image Management – IT can manage one primary image and synchronize it with thousands of endpoints Hardware Migration – By replacing the Base Image associated with an end user's PC, the user's desktop, including applications, data, and personalization settings, can be migrated to new hardware, including hardware from a different manufacturer. This process can be used as part of a regular hardware migration process, or to quickly replace a lost, stolen or broken PC. Remote repair of a damaged application – By ‘Enforcing’ a Base Image, IT can ensure a remote device exactly matches the primary copy in the data center, and repairing OS or core application problems. In place migration from Windows XP to Windows 7 - By replacing the Base Image associated with an end user's PC, the user's desktop, including data and personalization settings, can be migrated from Windows XP to Windows 7, over the network and without added infrastructure. Differences between VMware Mirage and Virtual Desktop Infrastructure (VDI) Virtual Desktop Infrastructure, or VDI, was initially branded by VMware. The term VDI has enjoyed broader usage, however, and has come to be known as a synonym for server-hosted desktop virtualization, or Hosted Virtual Desktops (Gartner). A typical VDI architecture replaces end users desktops by deploying each desktop on a virtual machine, running on a server in the data center. Users access a view of their desktop via a thin client or other access device, using a vendor-specific protocol. VMware Mirage differs fundamentally from this type of architecture in the following ways: No hypervisor required: While Mirage can operate within a Type-1 or Type-2 hypervisor, it is not required. The VMware Mirage client operates as a service within the Windows Operating System (OS). Scalability: Because VDI uses centralized servers to handle all processing functions for each desktop, a typical server can support roughly 10-12 users, depending on load. Mirage uses the endpoints for processing, and can consequently scale to a 1500:1 desktop to server ratio. Deployment: In most environments, Mirage deployment leverages components an organization already has in place: endpoint PCs, a server, and back-end storage. End users do not change their workflow, Network optimizations: Mirage leverages a global single index that enables significant deduplication across all users, reducing network traffic and storage requirements. Storage: Because VDI users require synchronous
