Abstract: Facility for using images created by backup software to recreate an entire machine as it was at the point in time in the past when the backup was taken. The facility can be extended so as to bring up a set of machines which together serve some logical business function as in a cluster or federated servers, and further extended so that an entire data center may be virtualized from backup images. The virtualized servers provided may serve as an alternate data center standing in case of disaster or to meet maintenance windows achieving low cost Instant Disaster Recovery. A set of virtual machines may stand in for physical machines for a period of time and then resynchronized or re-seeded to physical machines via a combination of bare metal recovery and re-synchronizing from live LUNs that form the virtual machine disks.

Abstract: A pressure support system includes a pressure generator, a pressure sensor, a flow sensor, and a controller cooperating with the pressure sensor and the flow sensor to control operation of the pressure generator. The controller is structured to automatically identify a patient interface device in use with the pressure support system by detecting a change of exhaust flow of up to a predetermined amount across a predetermined pressure gradient of a pressure range of the pressure support system.

Abstract: Systems and programs for improving the efficiency of a sorting process in a computer system are disclosed. Data is provided in an input file external to the central processing unit of the computer system. In one embodiment, the implemented process involves investigating the contents of the input file in order to identify presorted portions thereof; incorporating the identified presorted portions of the input file into a second file external to the central processing unit, performing this step by rearranging directory information, without physically transferring the presorted portions from the input file. In sort processes involving both a string generation phase and a merge phase, the techniques described may be used in either or both phases, as well as in any output phase. Rearranging directory information rather than physically transferring data provides for greater efficiency in disk I/O.
