Abstract: Disclosed is a method of providing virtual volumes to at least one host. Physical drives are grouped. Data is mirrored within groups to create a RAID-1 protected virtual drive. Data is also mirrored from the first virtual drive on a second virtual drive to create a hot spare virtual drive to act as a replacement for the RAID-1 protected virtual drive.

Abstract: A scroll wheel hinge assembly for an electronic device is described. The scroll wheel hinge assembly may be used for an electronic device that pivotally connects a flip module with a base module having a keypad. The flip module has a front face with an internal display and a back face with an external display. The hinge assembly includes a cylindrical rotatable assembly, a flip-closed position, and a flip-open position. More particularly, the cylindrical rotatable assembly is configured to enable the flip module to rotate in relation to the base module about a rotatable axis associated with the cylindrical rotatable assembly. The cylindrical rotatable assembly also includes either a free-wheel or a touch sensitive component on the exterior of the cylindrical assembly. In the illustrative embodiment, the touch sensitive component is configured to perform a scroll function that includes a scroll-up operation and a scroll-down operation.
