Storage virtualization systems and methods that allow customers to manage storage as a utility rather than as islands of storage which are independent of each other. A demand mapped virtual disk image of up to an arbitrarily large size is presented to a host system. The virtualization system allocates physical storage from a storage pool dynamically in response to host I / O requests, e.g., SCSI I / O requests, allowing for the amortization of storage resources-through a disk subsystem while maintaining coherency amongst I / O RAID traffic. In one embodiment, the virtualization functionality is implemented in a controller device, such as a controller card residing in a switch device or other network device, coupled to a storage system on a storage area network (SAN). The resulting virtual disk image that is observed by the host computer is larger than the amount of physical storage actually consumed.

A control system for controlling an infusion pump, including interface components for allowing a user to receive and provide information, a processor connected to the user interface components and adapted to provide instructions to the infusion pump, and a computer program having setup instructions that cause the processor to enter a setup mode upon the control system first being turned on. In the setup mode, the processor prompts the user, in a sequential manner, through the user interface components to input basic information for use by the processor in controlling the infusion pump, and allows the user to operate the infusion pump only after the user has completed the setup mode.

A virtualization infrastructure that allows multiple guest partitions to run within a host hardware partition. The host system is divided into distinct logical or virtual partitions and special infrastructure partitions are implemented to control resource management and to control physical I / O device drivers that are, in turn, used by operating systems in other distinct logical or virtual guest partitions. Host hardware resource management runs as a tracking application in a resource management “ultravisor” partition, while host resource management decisions are performed in a higher level command partition based on policies maintained in a separate operations partition. The conventional hypervisor is reduced to a context switching and containment element (monitor) for the respective partitions, while the system resource management functionality is implemented in the ultravisor partition. The ultravisor partition maintains the master in-memory database of the hardware resource allocations and serves a command channel to accept transactional requests for assignment of resources to partitions. It also provides individual read-only views of individual partitions to the associated partition monitors. Host hardware I / O management is implemented in special redundant I / O partitions. Operating systems in other logical or virtual partitions communicate with the I / O partitions via memory channels established by the ultravisor partition. The guest operating systems in the respective logical or virtual partitions are modified to access monitors that implement a system call interface through which the ultravisor, I / O, and any other special infrastructure partitions may initiate communications with each other and with the respective guest partitions. The guest operating systems are modified so that they do not attempt to use the “broken” instructions in the x86 system that complete virtualization systems must resolve by inserting traps. System resources are separated into zones that are managed by a separate partition containing resource management policies that may be implemented across nodes to implement a virtual data center.

A system and method for providing a peer-to-peer photo-sharing environment. The system includes: manual and automatic photo annotation at the client; periodic client-server synchronization; an index of client photos on a central server or a photo database that is resident on the central server, which is updated by the client-server synchronization function; end-user search functionality to search the centralized index or photo database; and transmission of the relevant photos to the client via an on-line image cache. In one embodiment, one client's new photos are automatically displayed on another client's computer (e.g., via screen saver or another mechanism).

A method for providing access to a computing environment includes the step of receiving, by a broker machine, a request from a client machine for access to a computing environment, the request including an identification of a user of the client machine. One of a plurality of virtual machines is identified by a session management component, the identified virtual machine providing the requested computing environment. One of a plurality of execution machines is identified, the identified execution machine providing a terminal services session in which a hypervisor executes to provide access to hardware resources required by the identified virtual machine. The hypervisor launches the identified virtual machine. A connection is established between the client machine and the identified virtual machine, via the terminal services session.
