Abstract
A virtualization system provides virtualized servers at a branch network location. Virtualized servers are implemented using virtual machine applications within the virtualization system. Data storage for the virtualized servers, including storage of the virtual machine files, is consolidated at a data center network location. The virtual disks of the virtualized servers are mapped to physical data storage at the data center and accessed via a WAN using storage block-based protocols. The virtualization system accesses a storage block cache at the branch network location that includes storage blocks prefetched based on knowledge about the virtualized servers. The virtualization system can include a virtual LAN directing network traffic between the WAN, the virtualized servers, and branch location clients. The virtualized servers, virtual LAN, and virtual disk mapping can be configured remotely via a management application. The management application may use templates to create multiple instances of common branch location configurations.
