Abstract: A storage system and a method for realizing a storage system is disclosed, the storage system comprising: a disk array comprising at least one solid state disk and at least one non-solid state disk; and a storage control means configured to: in response to entering a scrubbing mode, scan and move data blocks in the at least one non-solid state disk in the disk array to form more continuous free blocks. The storage system of the present invention has good read and write performances, higher data reliability and availability, and lower cost.

Abstract: A device comprising means for engaging said device to at least a portion of an outside surface of a glass of a headwear, means for engaging said device to at least a portion of an inside surface of glass of said headwear, means for mounting a display module or video capturing device and said means for engaging said device to at least a portion of an inside surface of a headwear to said device, and means for adjusting a viewing angle of said display module or video capturing device with a generally 360 degrees rotation.

Abstract: A system for a package pre-fetching for a remote program installation. The system includes a cache and a service program unit. The service program unit receives a request for a package required for an installation of an operating system and at least one peripheral application thereof from a computing node. The service program unit determines a package request sequence by which the computer node issues one or more package requests according to a type of the computing node, so as to pre-read a subsequent package from an external storage device into the cache before the computing node issues a request for the subsequent package.
