  • Redundant layer 2 domain interconnection
    Patent number: 11018926
    Abstract: Redundant Layer 2 Domain Interconnection may be provided. First, a first device in a first domain may be designated as an active device in response to the first device in the first domain negotiating with a second device in the first domain. The first device in the first domain may be connected to a first device in a second domain. The first domain may use a first protocol and the second domain may use a second protocol. Next, the first device in the first domain in response to being designated as the active device, may allow data traffic to pass between the first device in the first domain and the first device in the second domain. Then the second device in the first domain may be designated as a standby device in response to the first device in the first domain negotiating with the second device in the first domain. The second device in the first domain may be connected to a second device in the second domain.

  • Drive level flow-field conditioning to reduce flow field turbulence
    Patent number: 6989959
    Abstract: A flow control device for a data storage system to reduce flow induced vibration. The flow control device includes a plurality of streamline flow passages to reduce turbulent flow in a flow field along a disc surface. Thus, air flow induced by rotation of data discs is directed through the plurality of streamline flow passages to reduce turbulence to limit excitation or vibration of the head and suspension components.

  • Arm and suspension shroud for a disc drive
    Patent number: 6496327
    Abstract: A shroud mounted to the housing of a disc drive blocks wind to the arm and suspension that positions a slider adjacent a recording surface of a disc. A first wall has a windward surface facing into the direction of rotation of the first disc. A second wall extends downwind from the windward surface between the arm and the disc to from a low-wind region with the first wall. The region is open at the leeward side so that the arm in the low-wind region positions the slider adjacent the disc. In some embodiments, a third wall is parallel to the second wall so that the low-wind region is a slot.
