## Background
TECHNICAL BACKGROUND
Computer and network systems such as personal computers, workstations, server systems, and cloud storage systems, typically include data storage systems for storing and retrieving data. These data storage systems can include data storage devices, such as hard disk drives, solid state storage devices, tape storage devices, and other mass storage devices.
One approach to providing sufficient data storage is the use of arrays of independent data storage devices. A number of data storage devices can be held in a container, sometimes referred to as a sled. A sled is a modular unit that can hold and operate a number of independent data storage devices in an array. The data storage devices are held and operated in close proximity within the sled, so that many data storage devices can be fit into a defined volume. Installing data storage devices into sleds becomes increasingly difficult as the density of data storage devices within the sled increases. A sled can hold tens of data storage devices within an enclosure, with the enclosure including an external connector that is electrically coupled to all of the included data storage devices.
The enclosure can also include fans or other cooling devices. Rackmount enclosures can be used to hold very large amounts of data. Rackmount enclosures typically hold multiple sleds. The sleds aid in installing or removing the data storage devices from the rackmount enclosure. Consequently, storage capacity can be increased in large increments by the installation of an additional sled, sleds, or rackmount enclosures containing multiple data storage devices.
OVERVIEW
Data storage device mounting systems to provide alignment and mounting of data storage devices are provided herein. A carrier is configured to couple to a data storage device and hang the data storage device in a vertical orientation in a data storage assembly from retractable mounting pins coupled to the carrier. The carrier also includes retractable alignment features to guide the data storage device and carrier into the mounting system. Finger grips are coupled to retractable alignment features and mounting pins and configured to extend retractable alignment features beyond the carrier concurrent with retracting the mounting pins when actuated by a user squeezing the finger grips. The finger grips are configured to extend the mounting pins concurrently with retracting the retractable alignment features when de-actuated by the user.
Additionally, data storage assemblies for holding an array of data storage drives are provided herein. The data storage assemblies include a plurality of carriers configured to couple to associated data storage drives, each of the plurality of carriers comprising retractable alignment projections that extend during insertion of the associated data storage drives into the data storage assembly and retractable hanging pins that retract during insertion of the associated data storage drives into the data storage assembly. The retractable alignment projections are configured to prevent insertion of the associated data storage drives into the data storage assembly beyond a predetermined depth and align electrical connectors of the associated data storage drives with electrical connectors of the data storage assembly. The data storage assemblies for holding an array of data storage drives include a plurality of drive dividers comprising alignment guides configured to assist alignment of the plurality of carriers upon insertion into the data storage assembly. The plurality of drive dividers are configured to interface with the retractable hanging pins to support the data storage devices from an associated one or the plurality of carriers.

Mounting pins 110 are configured to engage hanging features 118 of data storage assembly 108 to support data storage device 106 in a vertical orientation in data storage assembly 108. Mounting pins 110 are coupled to finger grips 112. Mounting pins 110 are extended when finger grips 112 are not actuated. Mounting pins 110 retract when finger grips 112 are actuated. In this particular example, mounting pins 110 have a circular cross-section and the corresponding hanging features 118 are configured to engage mounting pins 110 having a circular cross-section. However, different cross-sectional shapes such as squares, rectangles, triangles or other cross-sectional geometries will can be used as mounting pins 110 to support data storage device 106 in a vertical orientation within data storage assembly 108
Finger grips 112 are coupled to mounting pins 110 and retractable alignment features 114 and configured to protrude retractable alignment features 114 concurrent with retracting mounting pins 110 when actuated to provide at least alignment during insertion of data storage device 106 into data storage assembly 108. Alternatively, finger grips 112 are configured to extend mounting pins 110 concurrent with retracting retractable alignment features 114 when de-actuated by the user. The size and shape of finger grips 112 can vary along with the data storage device carrier 100 to accommodate a variety of data storage devices 106.
Retractable alignment features 114 are configured to engage alignment guides 116 to provide alignment of data storage device 106 during insertion of data storage device 106 into data storage assembly 108.

In this particular example, retractable alignment features 114 have a rectangular cross-section. However, the cross-section of retractable alignment features 114 can be square, circular, triangular or some other geometry capable of engaging associated alignment guides 116.
Data storage device 106 is a representation of a generic data storage device. Many data storage devices have external mounting features 104. The size, shape, and type of external mounting features 104 will vary by make, model and brand of data storage device. Therefore, data storage device carrier 100 is configurable to couple to different types of data storage devices while retaining the features described herein.
Device mating features 130 couple data storage device carrier 100 to data storage device 106 via external mounting features 104. Device mating features 130 can vary in size, shape and type to accommodate different makes, models and brands of data storage devices.

Alignment guides 116 may have a tapered shape that permits initial misalignment between retractable alignment features 114 and alignment guides 116 upon insertion of data storage device carrier 100 into data storage assembly 108. Alignment guides correct alignment of data storage device during the insertion of data storage device 106 into data storage assembly 108. Alignment guides 116 may be comprised of many different shapes that can permit an initial amount of misalignment and correct the misalignment as data storage device carrier 100 is inserted into data storage assembly 108.
Hanging features 118 support data storage device carrier 100 and data storage device 106 in a vertical orientation within data storage assembly 108. Hanging features 118 are configure to mate with mounting pins 110. In this particular example, hanging features 118 are shown as having a circular cross-section. Hanging features 118 can have a variety of cross-sectional shapes such as squares, rectangles, or triangles so long as hanging features 118 are capable of mating with mounting pins 110.
Many manufacturing technologies can be employed to manufacture data storage device carrier 100, mounting pins 110, finger grips 112, retractable alignment guides 114, device mating features 130, alignment guides 116, and hanging features 118. Plastics, injection molded plastics in particular, are suitable for manufacturing data storage device carrier 100, mounting pins 110, figure grips 112, retractable alignment guides 114 and device mating features. However, these features can be made from a variety of materials. For example aluminum, steel, composites or other materials capable of providing sufficient structure and physical properties to secure data storage device 106 in a vertical orientation within data storage device assembly 108 can be used.
Data storage assembly 108 may also secure data storage device 106 in a horizontal orientation. Retractable alignment features 114 and alignment guides 116 also function when inserting a data storage device 106 into data storage assembly 108 horizontally. Alignment guides 114 can be configured to interface with data storage device carrier 100 to provide alignment in addition to retractable alignment guides 114.

The size and shape of retractable alignment features 414 and associated alignment guides 416 can vary along with carrier 402 to accommodate different makes, models and brands of data storage devices. In this particular example, retractable alignment features 414 have a rectangular cross-section. However, the cross-section of retractable alignment features 414 can be square, circular, triangular or some other geometry.
Data storage device 406 is a representation of a generic data storage device. Sizes, shapes, and external mounting features 404 will vary by make, model and brand of data storage device. Therefore, carrier 402 must be configurable to couple to different types of data storage devices while retaining the features described herein. Data storage device 406 comprises external mounting features 404 and electrical connector 422.
Data storage assembly 408 secures data storage device 406 in a vertical orientation and provides electrical communication to data storage device 406. Data storage assembly comprises alignment guides 416, hanging features 418, viscoelastic grommets 420, and electrical connections 424.
