## Background
This application is a continuation application of Ser. No. 14/532,473 filed Nov. 4, 2014.


FIELD OF THE INVENTION
The present invention relates generally to the data processing field, and more particularly, relates to a method and apparatus for implementing enhanced rack design to improve component and cable access.
DESCRIPTION OF THE RELATED ART
When servers are integrated into a rack, traditionally the manufacturer installs a set of base system cables before shipping the server system to the customer. The customer then installs the rest of their I/O cables. Traditionally, to ease the customer's installation process, base cables are installed in the innermost corner of the rack side wall cabling space. This allows space for customers to easily install their own cables.
Referring to FIGS. 4A, 4B, and 4C typical cabling in an example prior art rack design are shown. As shown in the respective rack top views of FIGS. 4A and 4B, and in the rack back view of FIG. 4C, areas near an outer side wall of the inside of the server rack are blocked to rear access making it impossible or difficult to add and/or service cables.
On many servers the base cable bulk wire is significantly thicker than the customer I/O cables and consequently the bend radius of the base system cables consumes much of the cable space in the side walls. Because of this increase in bend radius, customers are left with less room to add customer I/O cables. Currently customers must either decrease processing power to reduce the number of cables or add rack extensions. However, these solutions are unfeasible for several customers, such as ones with limited floor space, or ones who require the more processing power.
A need exists for an effective mechanism for implementing an increase in processing power without adding any extensions when using high bulk wire in a server rack design.
SUMMARY OF THE INVENTION
Principal aspects of the present invention are to provide a method and apparatus for implementing enhanced rack design to improve component and cable access in a computer system. Other important aspects of the present invention are to provide such method and apparatus substantially without negative effects and that overcome many of the disadvantages of prior art arrangements.
In brief, a method and apparatus for implementing enhanced rack design to improve component and cable access in a computer system. A server rack includes a side rack cable access area. An elongated bracket member includes multiple openings for receiving cable ties. The cables ties are used to secure predefined cables. The elongated bracket member is unlatched from an inside wall of the rack. The elongated bracket member together with the secured system cables is pivoted away from customer cables routing area.
In accordance with features of the invention, the elongated bracket member together with secured system cables is unlatched from the rack and pivoted without disconnecting the secured predefined cables.
In accordance with features of the invention, when the elongated bracket member is unlatched, the bracket is free to move as far as a cable service loop allows.
In accordance with features of the invention, one or more of the secured system cables optionally are removed from the elongated bracket member for maintenance to be performed.
In accordance with features of the invention, the elongated bracket member is latched to an inside wall of the rack with a minimized bend radius of the secured predefined cables.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the following detailed description of embodiments of the invention, reference is made to the accompanying drawings, which illustrate example embodiments by which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the invention.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
In accordance with features of the invention, a method and apparatus are provided for implementing enhanced rack design to improve component and cable access in a computer system.
Having reference now to the drawings, in FIG. 1, there is shown example functional operations for implementing enhanced rack design generally designated by the reference character 100 to improve component and cable access in a computer system in accordance with a preferred embodiment.
Referring also to FIGS. 2A, 2B, 2C, and 2D, example apparatus generally designated by the reference character 200 is shown (not to scale) for implementing enhanced rack design to improve component and cable access in a computer system in accordance with a preferred embodiment.
As indicated in a block 102, an elongated bracket member having a plurality of holes for receiving cable ties is provided. For example, a metal elongated strip bracket or a stamped and formed hard plastic elongated strip bracket with holes is provided. A bracket 206 such as illustrated in FIGS. 2A, 2B, 2C, and 2D, implements the elongated bracket member.
As indicated in a block 104, cable ties are provided with selected holes of the elongated bracket member to secure one or more system cables, such as server base system cables. The cable ties secure predefined cables, such as cables 204 such as illustrated in FIGS. 2A, 2B, 2C, and 2D.
As indicated in a block 106, the elongated bracket member with the secured system cables is unlatched from an inside wall corner of the rack. For example, a quick connect latch is used to attach the elongated bracket member at an inside server wall location, such as indicated by quick-connect latch 210 in FIG. 2A.
As indicated in a block 108, the bracket is pivoted with the secured system cables providing access to a customer I/O cable routing area. The unlatched bracket can be pivoted as far as cable service loop allows, for example to add and/or service cables without disconnecting system cables. In FIG. 2A, the bracket 206 is shown in the closed position. In FIG. 2C, the bracket 206 is shown in the open position with the bracket disconnected from the server rack to provide access area 212 open to rear access to add and/or service customer cables. In the rack back view of FIG. 2D, an access area 214 open to rear access to add and/or service customer cables is indicated.
Referring now to FIGS. 3A, 3B, 3C, 3D, 3E and 3F, further example apparatus generally designated by the reference character 300 is shown for implementing enhanced rack design to improve component and cable access in a computer system in accordance with a preferred embodiment. FIGS. 3A and 3C provide rack top views of example apparatus 300. FIGS. 3B, 3D, 3E, and 3F provide rack rear views of example apparatus 300.
Apparatus 300 includes a system drawer 302, predefined base server system cables 304, and dual sided brackets 306, each with a respective quick-connect latch 310.
As shown in FIG. 3A, both brackets 306 are shown in the closed position. In FIG. 3C, the bracket 306 on the right side is shown in the open position with the bracket disconnected from the server rack to provide access for customer cables as indicated by access area 312 open to rear access to add and/or service cables.
In a rack rear view of FIG. 3D, an access area 314 is illustrated that is open to rear access to add and/or service cables.
In a rack rear view of FIG. 3F that illustrating brackets 306 for each drawer or rack section, an access area 316 is illustrated that is open to rear access to add and/or service cables.
In accordance with features of the invention, the enhanced rack design enables improved component and cable access in a computer system where the base server system cables never need to be removed from the bracket unless maintenance needs to be performed on the base server system cables. Each bracket 206, 306 attached to the outer edge of the inside corner wall of the rack is easily unlatched. When the bracket 206, 306 is unlatched, the bracket is free to pivot as far as the cable service loop allow, providing an access area open to rear access to add and/or service customer cables.
While the present invention has been described with reference to the details of the embodiments of the invention shown in the drawing, these details are not intended to limit the scope of the invention as claimed in the appended claims.
