Abstract: A high efficiency self-contained modular turbine engine unit for generating power includes a housing defining an air intake and an exhaust port. A turbine engine is positioned and operable within the housing. The turbine engine includes a drive shaft a compressor rotor assembly, a compressor vane assembly, a combustor and diffuser assembly, a turbine vane assembly and a turbine rotor assembly. The combustor and diffuser assembly is a one-piece unit defining a shroud extending forwardly therefrom and a plurality of combustion flow channels extending rearwardly and radially inwardly thereby forming a flowpath angle. In one embodiment, the flow path angle is in the range from about 15° to about 35° with the drive shaft. An igniter is positioned in each flow channel to ignite a fuel/oxygen mixture introduced into the compressor rotor assembly. External components required for operation of turbine engine are mounted within the housing.

Abstract: Systems and methods for restriping files distributed among a set of smart storage units, wherein data blocks for a particular stripe do not typically need to be located at any particular location on the storage units, wherein data can be typically restriped among the smart storage units with minimal data movement, and wherein data is typically protected and recoverable even if a system failure occurs during the restriping process.
