This application is a continuation-in-part pursuant to 37 C.F.R. §1.53(b) of U.S. patent application Ser. No. 11/653,414, filed Jan. 11, 2007, which claims priority from U.S. Provisional Application Ser. No. 60/761,219 filed Jan. 11, 2006, both of which are incorporated herein by reference in their entirety for all purposes.


FIELD OF THE INVENTION
The invention relates generally to shelf and rack systems for servers and electronic components and more particularly to apparatus and methods for minimize vibration from servers and electronic components.
BACKGROUND
Data centers and server racks are extremely noisy places. The noise resulting from vibration can be significant. Multiple sources of vibration contribute to the vibration level of server racks in data centers including but not limited to Computer Room Air Conditioners (CRACS) for building and racks, chillers, building, rack, and server transformers, building/rack Un-interruptible Power Supplies (UPS) and rack/server/Hard Disc Drives (HDD) and cooling fans. These are all very noisy and collectively create a very complex and high level of vibration at wide ranges of frequency. Vibration levels at data centers, server racks and servers vary and typically can be 1 g or more.
Existing server racks are fabricated without vibration dissipating measures. Generally made from steel sheet metal, existing rack structures actually magnify vibration rather mitigating it.
Hard Disc Drives are very sensitive to vibration. When looking for a file to read, the head is moving inward or outward as the disc is spinning, in order to locate the beginning of the file. Vibration makes this task more difficult as the head searches for the file location on the disc. HDD manufacturers have implemented vibration sensors in the HDDs to sense vibration and pause I/O operation in presence of high vibration. Input/Output (I/O) becomes much faster and more efficient as vibration is suppressed. Generally, write operations take longer than read operations and are more sensitive to vibration. Many server/computer operations are I/O—intensive workloads, e.g. On-line transaction processing (OLTP) applications, video streaming, web serving, finance applications, etc.
Vibration at wide ranges of frequencies interferes with HDD operation and in some cases causes the corresponding server or computer to shut down. As a result, there is a need for anti-vibration measures at various frequencies to dissipate vibration in servers allowing HDDs to perform much more efficiently.
The relationship between an arbitrary vibration force F and the resulting motion X of a multiple degree of freedom structure can be presented as: MX′′+CX′+KX=F
Where X is displacement (motion), X′ velocity, X′′ is acceleration, M represents mass, C damping and K stiffness of the structure. Stiffness and damping properties of materials and structures vary with operational frequencies.
Embodiments of the novel anti vibration rack optimize structural stiffness and damping to mitigate vibration at all operating frequencies in servers and data centers.
The selection of materials may also influence the performance of a system. Materials that aid in minimizing vibration exist. An example of such is carbon fiber composites.
Carbon fiber generally refers to carbon filament thread, or to felt or woven cloth made from those carbon filaments. The term carbon fiber is also used to mean any composite material made with carbon filament, such a material is sometimes referred to as graphite-reinforced plastic.
Each carbon filament is made out of long, thin filaments of carbon sometimes transferred to graphite. A common method of making carbon filaments is the oxidation and thermal pyrolysis of polyacrylonitrile (PAN), a polymer used in the creation of many synthetic materials. Like all polymers, polyacrylonitrile molecules are long chains, which are aligned in the process of drawing continuous filaments. When heated in the correct conditions, these chains bond side-to-side (ladder polymers), forming narrow graphene sheets which eventually merge to form a single, jelly roll-shaped or round filament. The result is usually 93-95% carbon. Lower-quality fiber can be manufactured using pitch or rayon as the precursor instead of PAN. The carbon can become further enhanced, as high modulus or high strength carbon, by heat treatment processes. Carbon heated in the range of 1500-2000° C. (carbonization) exhibits the highest tensile strength (820,000 psi or 5,650 MPa or 5,650 N/mm2), while carbon fiber heated from 2500 to 3000° C. (graphitizing) exhibits a higher modulus of elasticity (77,000,000 psi or 531 GPa or 531 kN/mm2).
There are several categories of carbon fibers: standard modulus (250 GPa), intermediate modulus (300 GPa), and high modulus (>300 GPa). The tensile strength of different yarn types varies between 2000 and 7000 MPa. The density of carbon fiber is 1750 kg/m3.
Precursors for carbon fibers are PAN, rayon and pitch. In the past rayon was more used as a precursor and still is for certain specialized applications such as rockets and specific aerospace applications. Carbon fiber filament yarns are used in several processing techniques: the direct uses are for prepregging, filament winding, pultrusion, weaving, braiding and the like.
The filaments are stranded into a yarn. Carbon fiber yarn is rated by the linear density (weight per unit length=1 g/1000 m=tex) or by number of filaments per yarn count, in thousands. For example 200 tex for 3,000 filaments of carbon fiber is 3 times as strong as 1,000 carbon fibers, but is also 3 times as heavy. This thread can then be used to weave a carbon fiber filament fabric or cloth. The appearance of this fabric generally depends on the linear density of the yarn and the weave chosen. Carbon fiber is naturally a glossy black but colored carbon fiber is also available.
Carbon fiber may be used to reinforce composite materials, particularly the class of materials known as carbon fiber reinforced plastics. This class of materials is often used in demanding mechanical applications. Carbon fiber's unique properties such as high stiffness, high strength, high damping, low density, and corrosion resistance are ideal for demanding applications. Carbon fiber/epoxy composites have mechanical properties such as the stiffness and strength of steel, and damping of 10 times more than aluminum at 30% lower density.
While non-polymer materials can also be used as the matrix for carbon fibers, due to the formation of metal carbides (i.e., water-soluble AlC), bad wetting by some metals, and corrosion considerations, carbon is used less frequently in metal matrix composite applications.
Vibration may interfere with the operation of HDDs, cooling fans and other server components resulting in reduction of performance and increase in energy consumption. Therefore there is a need for a means to minimize or eliminate vibration. In order to address the vibration, embodiments of the present invention provide for a novel anti-vibration rack (AVR) that dissipates vibration at wide frequency ranges. For example, the novel AVR may dissipate vibration from 10 Hz to several thousand and perhaps in several hundred thousand Hz. The frequency range of interest in HDD operation is preferably from 50 Hz to 2,000 Hz. Testing of various embodiments of the novel server AVR verify the effect of its anti-vibration technologies on servers' performance and energy consumption. Embodiments of the novel AVR dissipate vibration passively, effectively eliminating vibration in all interested frequency ranges.

FIG. 1 depicts a perspective view of an AVR 100. The AVR 100 may preferably be designed and manufactured using aerospace structural and isolation principles. The AVR 100 is preferably constructed primarily from materials that assist in minimizing vibration and other interference. Carbon fiber composites are one such material and are one of the optimal materials for these purposes. Various acrylics are also suitable for such purpose. In contrast, glass and metals are less desirable for damping and minimizing the effects of vibration, oscillation and the like.
Carbon fiber composite materials offer an excellent damping/stiffness combination. When a structure, like an AVR is designed properly, it dissipates vibration the most effectively as it utilizes stiffness, damping and mass. That dissipation may be maximized by selecting a material well suited for the purpose, a carbon fiber composite is such a material.
The AVR 100 has a first side panel 110 and a second side panel 120. The AVR 100 also has an upper panel 130 and a lower panel 140. The first side panel 110, second side panel 120, upper panel 130 and lower panel 140 form a box-like structure having an open face 150. The upper panel 130, lower panel 140 and side panels 110, 120 may be constructed from materials as described above. In another embodiment some or all of the panels may be constructed from alternative materials. For example in one embodiment, some or all of the panels are plastic with or without fiberglass or carbon fiber reinforcement. In another embodiment, some or all of the panels are plastic with foam cores. In embodiments including foam cores, the panels may be molded with internal foam cores that are injected or comprised from sheets of foam. Alternatively, in embodiments including foam cores, the panels may be constructed as laminate layer with foam between the layers throughout or at the median of the layers. Preferably the upper, lower and side panels are 1⁄8′′ to 1′′ thick. However, in some instances it may be preferable to have thicker panels for example because of the strength needed to support the weight of the components contained in the cabinet.
The first side panel 110 and the second side panel 120 each have an inner surface 112, 122 and an outer surface 114, 124. The outer surface 114,124 may be textured or smooth; the inner surface 112,122 is configured with grooves to support servers or other electronic equipment. Although depicted as a box like structure, this is not intended to be a limitation on the present invention. It is contemplated that an open shelving style system could also be constructed; in addition, it is contemplated that within a box like structure, additional side panels could be installed so that multiple sub-boxes exist within a larger box. In one embodiment, angled brackets may be attached at the inner or outer corners of the box like cabinet structure to strengthen the AVR. In another embodiment, angle brackets may be attached to the corner faces of the box like cabinet structure. FIGS. 6A-6C depict exemplar brackets. FIG. 6A illustrates a corner “L” bracket that may be fastened on the inside or outside surface of the AVR. FIG. 6B show a face mount “L” bracket configured to be mounted on the outside of the AVR. FIG. 6C depicts an inside corner bracket. The brackets shown are illustrative only and not intended to be a limitation on the size, or shape of bracket that may be utilized to further strengthen the AVR. Furthermore, the brackets may limit movement of the AVR thereby providing further strengthening. The brackets may be comprised of any commercially available material including but not limited to metal.
FIG. 2 is a front view on an AVR 200 according to an embodiment of the present invention. The AVR 200 described herein is designed to dissipate vibration passively in various frequencies, which interfere with operation of HDDs, cooling fans and other server components. The AVR 200 consists of a rack cabinet similar to that described in conjunction with FIG. 1. The AVR 200 may be constructed in various sizes and configuration so that the shelves and/or server mounts are capable of supporting various size servers. The configuration shown herein is not intended to be a limitation on the embodiments of the present invention. AVR 200 also referred to herein as a rack cabinet, consists of four sections: two side panels 203 and 204, an upper panel 201 and a lower panel 202. The side panels 201 and 202 have drawer type grooves 205 or other track systems for shelves. Other track systems that may be used include but are not limited to bars, retracting arms, ball bearing systems, peg systems, and fixed shelves.
A server 250 may be placed on a server shelf support assembly 206 and can then be slid in and out of an AVR. The server shelf assembly 206 may be constructed from any variety of materials. For example, carbon fiber composite or fiberglass composite materials offer an excellent damping/stiffness combination. The shelf assembly system 206 comprises a shelf plate 210, and two strip bars, one of polyurethane, i.e. sorbothane, and one of carbon fiber attached by fasteners (not shown), or other mechanical means, to the side of the shelf plate 210.

Preferably the shelf 210 is approximately 0.25′′ thick. In one embodiment, a 1′′ thick acrylic material shelf without fiber re-enforcement is implemented. The shelf plate 210 may be constructed from carbon fiber or fiberglass or any other suitable material. Fiberglass is preferably used for cost savings. In one embodiment having multiple shelves. one or more shelves are carbon fiber while the other one or more shelves are fiberglass. The carbon fiber shelves are preferably constructed using lamination techniques or molding techniques. The shelves may be constructed by molding or extrusion process or in the form of multiple plys of sheets of carbon fiber, i.e. laminate construction as disclosed above. Alternatively, the shelf plate 210 may be constructed from medium-density fiberboard (“MDF”) or MDF with a carbon fiber veneer. Furthermore, the shelf plate 210 may also be constructed from acrylics or similar plastic materials such as polymethyl methacrylate (also known as “acrylic glass” and “Plexiglas®”), the synthetic polymer of methyl methacrylate, or an acrylic with a carbon fiber veneer. When a carbon fiber veneer is used, the veneer is 10/1000 to 199/1000 inch thick and preferably 30/1000 to 35/1000 inch thick. The carbon fiber veneer described above is a multi layer carbon fiber skin (i.e. a laminate process) which is bonded to all surfaces (top, bottom and sides) of the MDF or acrylic to create the shelf. Carbon fiber (CF) veneer has sheets of CF fabric or unidirectional CF or CF mat pressed and cured to make a solid sheet. The fibers are generally placed along the veneer plane. The carbon fiber blocks used in vibration mounts (described below) are preferably made from laminated sheets of CF placed and cut at optimal angles, such that oblique angles are created between the plans of the sheets, to maximize its stiffness, strength and damping characteristics. Preferably the sheets are constructed from axisymetric solid laminated carbon fiber epoxy composite laminates with an oblique angle between the plane of laminate and top plane of the shelf to provide optimal stiffness and damping. More preferably the angle is about 20 degrees. The carbon fiber blocks may also be made from chopped carbon fiber epoxy using a molding or extruding process, in addition other similar methods maybe used to fabricate a mount. Regardless of fabrication method, the carbon fiber is preferably cut in the preferred optimal angle. In addition, ional metal wire may be added to the carbon fiber fabric to enhance shielding capability. Although depicted as having only a single shelf assembly 206, such is not intended to be a limitation and the AVR may have any number of shelves based on the height/size of the AVR.
The server shelf assembly 206 is supported on the grooves 205. The groves 205 are located on the inner surface of the side panels 203, 204 and are parallel to the shelf assembly rack 206. The grooves 205 preferably extend the full depth of the rack cabinet 200. However, it is not required that the shelf 210 and/or the groove 205 extend the entire depth of the rack cabinet 200. Preferably the groove 205 will run the length of the shelf assembly 206 so that the shelf assembly 206 is supported along its entire side length. The grooves 205 may be evenly spaced or unevenly spaced along the inner surface of the side panels 203, 204.
In one embodiment, the preferred method of fabrication of the rack cabinet 200 is molded fiberglass re-enforced plastics. The rack cabinet 200 may also be made with other materials and methods to reduce cost.

Further, although described as being comprised of two blocks, the compression block may be comprised of a single block of any material capable of dissipating vibration or more than two blocks. The carbon fiber blocks dissipate vibration in mid and high frequency ranges while the polyurethane block dissipate vibration in low frequency range, generally below 200 Hz. The anti-vibration mount 312 is attached to the sides of a server via screws, using built-in screw holes on their sides for rack attachment. The polyurethane block 508 is compressed to its optimum compression which is preferably 10-15% by positioning it between the carbon fiber block 506 and the bracket. The anti-vibration mounts 312 are designed to ride and rest on the rack cabinet's 300 side grooves 305.
