  • Patent number: 9870805
    Abstract: A storage device includes a first portion including drive media, and a second portion. The second portion includes a first end wall that is in physical communication with first and second side walls, and a second end wall that is in physical communication with the first and second side walls. The second portion also includes a printed circuit board mounted within the cavity, a plurality of ribs within the cavity, and an air channel within the cavity. The air channel has a lower air flow impedance than other portions of the storage device including the first portion, the printed circuit board, and the ribs. The air channel extends along a direction between the first end wall and the second end wall of the storage device.

  • Publication number: 20170303437
    Abstract: A method of manufacturing a chassis that cools thermal energy generating components of an information handling system (IHS) includes: forming an enclosure with a chassis that has a base wall for provisioning a thermal energy generating component; forming one or more stiffeners each having one or more air channels formed transversely through for directing air proximate to the base wall; attaching the one or more stiffeners laterally across the base wall; and attaching a planar member that is horizontally on top of the one or more stiffeners for engaging one or more forward compute components on top of the planar member that substantially block air flow above the planar member to the thermal energy generating component. The one or more air channels eliminate thermal shadowing caused by thermal energy generating components provisioned in a rear area of the chassis.

  • Publication number: 20170269644
    Abstract: A component carrier may include a carrier front wall and a plurality of carrier side walls extending in a substantially parallel orientation to each other from opposite edges of the chassis front wall, and defining a component channel between them. The carrier side walls may include respective guide flanges extending substantially perpendicularly therefrom such that the guide flanges are in a substantially parallel orientation to each other and the guide flanges are oriented relative to the remainder of the component carrier such that when a component is mounted within the component channel to the component carrier, and the guide flanges may define a plane whereby a combined mass on a first side of the plane of the component carrier and the component is approximately equal to a combined mass on a second side of the component carrier and the component.

  • Patent number: 9723758
    Abstract: A chassis directs cooling air around compute components of an information handling system (IHS). The chassis includes an enclosure having a base wall, an air intake at a front side, and an air exhaust at a rear side. Stiffeners are attached laterally across the base wall and positioned between the front side and a rear area of the base wall. A planar member is horizontally attached on top of the one or more stiffeners. The planar member is provisioned with the compute components, which substantially block air flow above the planar member causing thermal shadowing of the thermal energy generating component that is provisioned in the rear area. Air channels formed through each of the stiffeners direct air flow under the planar member toward the rear area that is provisioned with the thermal energy generating component.

  • Patent number: 9317081
    Abstract: The side profile of a hard drive assembly may be configured with one or more open areas to allow cooling air to pass side-to-side through a lateral flow channel provided by a cavity defined in the base portion of the hard drive assembly. Corresponding and complementary open areas may be also be defined in mating drive carrier assembly side components to allow passage of lateral side-to-side cooling air through the base portion flow channel of a hard drive assembled to the drive carrier assembly to form a mountable hard drive system that is installed into a storage enclosure. The at least partially aligned open flow areas of the assembled hard dive assembly and drive carrier assembly may cooperate to reduce air flow impedance across multiple rows of hard drive systems through a storage enclosure.

  • Patent number: 9036291
    Abstract: Systems and methods are provided that may be implemented to provide a mechanical indicator to correlate magnetic disk drive IOP performance with features of mechanical and/or acoustic vibrational frequencies that are generated and captured or sensed outside of the disk drive itself. In one example, disk drive PES data may be collected concurrently with the capture of mechanical and/or acoustic vibrational data at different and progressive locations of vibration source, vibration path and vibration receiver in a disk drive operating environment, e.g., such as for disk drives installed within a server and/or storage chassis enclosure. In such case, PES threshold may be utilized to correlate performance of Drive IOP or drive servo-mechanical performance as a function of measured characteristics of vibration source/s that impart vibration to a disk drive.
