Filed:

Jun 27, 2008

Appl. No.:

12/215487

Inventors:

Joseph CaraDonna - Ashland MA, US
Brian McCarthy - Nashua NH, US

Assignee:

NetApp, Inc. - Sunnyvale CA

International Classification:

G06F 9/44
G06F 13/10
G06F 13/12
G06F 17/50

US Classification:

703 21, 703 13, 711203

Abstract:

A system and method of testing, during development, the operation of a clustered storage server system and its associated storage operating system. The system includes at least one host computer having a host operating system, and at least one virtual computer having a simulated storage operating system, at least one simulated disk, a simulated NVRAM, and a simulated flashcard within a guest operating system hosted by the host operating system. The simulated storage operating system represents an actual storage operating system. Facilities of the simulated storage operating system including the simulated disk, the simulated NVRAM, and the simulated flashcard are mapped onto corresponding facilities of the host operating system via virtualization components of the virtual computer so that the simulated storage operating system operates substantially the same as the actual storage operating system on low cost host hardware platforms.

Abstract:

Separation of particles or droplets from a host fluid may be achieved using a transducer and/or reflector that is a thin, non-planar structure. The thin non-planar structure improves operation of an acoustic standing wave generated by an acoustic transducer. The structure may operate as a pressure release boundary and may be constructed as plastic film.

International Classification:

G06F 11/14

Abstract:

A method, non-transitory computer readable medium, and computing device that determines when a software failure associated with a virtual storage controller has occurred. At least a portion of a transaction log corresponding to the virtual storage controller is stored in a stable storage device, when the determining indicates that the software failure associated with the virtual storage controller has occurred. A determination is made when the virtual storage controller has rebooted. The at least a portion of the transaction log is retrieved from the stable storage device, when the determining indicates that the virtual storage controller has rebooted. Thereby, state can be preserved and transactions pending, but not yet committed to storage server devices, can be replayed and proceed with minimal or no impact on the client devices originating the transactions.
