DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rack mount structure of a disk recording / reproducing apparatus which is most suitable for application to a multi-video server apparatus incorporating a plurality of disk drives.

[0002]

2. Description of the Related Art Conventionally, as a disk recording / reproducing apparatus of this kind, a processor (RAID) for managing overall control and a RAID (redundant arbor) provided with a plurality of disk drives.
(Japanese Patent Application Laid-Open No. H11-232854), there has been proposed a housing structure of a multi-video server device in which the components of a multi-video server device are combined into a single housing and the height of the device is suppressed to 220 mm (5 U). reference). This multi-video server device has a housing having a configuration in which the width and the depth are larger than the height. For example, the multi-video server device has a vertically long shape as shown in the front view of FIG. 22A and the side view of FIG. A plurality of multi-video server devices are installed in a rack 21 in a vertically multi-tiered manner so that many hard disks can be operated in parallel and used as a disk array. That is, in this type of multi-video server device, there is a case where a plurality of sets are connected and used in order to add a hard disk drive HDD to increase the recording capacity and to increase the number of slots and the number of channels. In the illustrated example, a maximum of eight racks 21 can be set.

Hereinafter, a mounting structure of the multi-video server device on the rack 21 will be described.
FIGS. 23 to 25 are front views showing a state where the multi video server device 10 is mounted on the rack 21 shown in FIG.
It is a top view and a side view. As shown, the rack 21
There is a pillar 21A standing at each corner, and this pillar 21A
A side plate, a top plate, and the like are appropriately attached to the device. An attachment member (so-called mount angle) 25 is attached to the pillar 21A. An outer support 28 that supports the multi-video server device 10 is attached to the attachment member 25 via a bracket 24. I have. On the other hand, inner supports 23 are attached to both sides of the housing 10A of the multi-video server device 10. The outer support 28 is formed in a rail shape along the front-rear direction of the rack 21, and the inner support 23 is also formed in a rail shape along the front-rear direction of the rack 21. The multi-video server device 10 is mounted on a rack 21 with the 23 placed on the outer support 28.

FIGS. 26 to 31 are perspective views for explaining the procedure when such a multi-video server device 10 is mounted on a rack 21. FIG. Hereinafter, the mounting method will be described with reference to these drawings. First, as shown in FIG. 26, the housing 10A of the multi-video server device 10 includes:
A leg 22 is provided for installation and use as a single unit, and is mounted on the rack 21 with the leg 22 removed. Also, as shown in FIG. 27, inner supports 23 are attached to both sides of the housing 10A of the multi-video server device 10. On the other hand, as shown in FIG.
As shown in FIG.
Is to be screwed and joined, and the bracket 2
By adjusting the mounting position of the rack 21 along the long hole, the depth of the rack 21 (for example, the mounting size of 650 mm to 7
(Range of 50 mm).

[0005] Such an outer support 28 is provided.
Is mounted on the mounting member 25 of the rack 21. That is, as shown in FIG. 29, the mounting member 25 is formed in a band shape along the up-down direction,
It has a mounting surface arranged in parallel along the side of the rack 21, and a large number of mounting holes are formed in the mounting surface at predetermined intervals along the vertical direction. On the other hand, the bracket 24 also has a mounting hole corresponding to the mounting hole of the mounting member 25. Therefore, the screws 26A are inserted through the mounting holes of the bracket 24 and the mounting member 25.
Is inserted and screwed with the opposite plate nut 26B to join the bracket 24 and the mounting member 25 together.
In this manner, by selecting the mounting hole of the mounting member 25 for mounting the bracket 24, the outer support 28 can be mounted at an arbitrary height position of the rack 21.

[0006] Next, as shown in FIG. 30, the multi-video server device 10 is placed inside the rack 21 so that the inner support 23 with the multi-video server device 10 is mounted on the outer support 28 attached to the rack 21. Insert Then, as shown in FIG. 31, a mounting piece (so-called rack angle) 29 provided on the housing 10 </ b> A of the multi-video server device 10 is screwed to the mounting member 25. That is, the attached piece 29 is
Mounting holes are provided on both sides of the front surface of the housing 10A and correspond to screw holes provided in the mounting member 25. Then, the decorative washer 27B and the attached piece 29
The multi-video server device 10 is fixed to the rack 21 by screwing a screw 27A with a washer into the screw hole of the mounting member 25 through the mounting hole.

Although details will be described later, in the multi-video server device 10, even if it is fixed to the rack 21, the internal hard disk drive unit, power supply unit and the like can be replaced. Therefore, the multi-video server device 10 can be fixed to the rack 21 by a simple and inexpensive support structure without using a complicated support structure for appropriately pulling out the multi-video server device 10 itself. Further, the outer support 28 described above is used.
25 (a in FIG. 25), the weight of the multi-video server device 10 (around 50 k) in the case of a support structure in which the multi-video server device 10 itself is appropriately pulled out.
In order to secure the strength when pulling out, for example, FIG.
25 (around 60 mm) is required, but due to the structure in which the multi-video server device 10 is not pulled out as in this example, a (around 30 mm) shown in FIG. 25 is sufficient. As a result, the exhaust port of the fan unit provided on the right side of the multi-video server device 10 is not blocked by the wide outer support, and an effective cooling effect can be secured.

[0008]

The multi-video server device 10 mounted on the rack 21 as described above.
In the case where a hard disk in a disk array is used, the acceleration applied to the hard disk may affect the performance. This means that when reading or writing an individual address of a hard disk, the recording head seeks to the track of the cylinder containing that address. In this type of disk array, the transfer rate required for MPEG signals is reduced. In order to secure, a random seek must be performed 6 to 8 times per second. Then, as in the hard disk drive 30 shown in FIG. A rotational angular acceleration in the direction is generated. But,
When the hard disk moves due to such acceleration, the servo that moves the head 31 is affected. Therefore, each hard disk maker provides an installation condition to make the installation robust, and a hard disk operation requires 0.5 G or more. When the acceleration is given, the operation is abnormal. Therefore, the installation condition is presented so as not to give the disturbance vibration.

[0009] Further, due to the acceleration generated by the hard disk, a force for exciting the multi-video server device 10 in the direction of arrow e in FIGS. 32 and 25 acts, and the entire multi-video server device 10 vibrates. Mounting piece 29
Is transmitted to the rack 21 via the mounting member 25. However, if the strength of the rack 21 is weak or the installation of the rack 21 is not strong, the rack 21 itself may vibrate greatly. In particular, the multi-video server device 10
When a plurality of are placed in one rack 21, the number of vibration sources increases, and the vibration of the rack 21 may further increase.
Other equipment may be installed in a studio or the like, and vibration from installation in the same room may be transmitted to the rack 21 through the floor, resulting in disturbance vibration.

[0010] Also, broadcasting stations and the like sometimes use equipment mounted on a relay van called an OB van for sports broadcasting or the like. In many cases, the equipment is mounted on a rack and mounted. When the relay truck shakes due to the road conditions during traveling due to the movement of the car and the racks vibrate greatly,
In the worst case, a step response impact may be applied to the rack due to a step on the road or the like. Each hard disk maker similarly presents installation conditions so as not to cause disturbance vibration, since the drive may be broken if these non-operating vibrations also exceed about 2 G.

On the other hand, in the above-described conventional rack mount structure, the outer servo 23, the inner support 28, and the bracket 24 are made of a steel material having a thickness of 1.5 to 2 mm. There are problems such as generating a high impact acceleration having a high frequency, acting as a spring against vibration, and having no damping property. That is,
When these vibrations are transmitted to the set through angles or the like, if the vibrations are large, the rack mount structure is such that the inner support 28 of the set is placed on the outer support 23 fixed to the rack 21 and only the front side is mounted. Since the piece 29 and the mounting member 25 are only fixed by screws, there is no structure for suppressing vertical vibration in the direction of arrow c in FIG.

For this reason, when the vibration frequency is close to the natural frequency of the rack installation, the vibration resonates and is amplified to have a vibration level several times as high as the self-vibration. Vibration was sometimes applied. At this time, if the hard disk is operating, the head access operation becomes unstable, the access time becomes longer, recoverable errors (recoverable errors), etc. occur, and the operation is performed within the normal specification time. May not end. Normally, in archival applications such as computers, data accuracy is required rather than operation delays due to retries and the like, and a delay of about one second rarely causes a problem.

However, in the recording for video and audio, data needs to be continuous with respect to time. Therefore, during data processing, the access time becomes longer due to the influence of acceleration or the like, and data transfer is performed within the time determined by the system. If it cannot be done, the video and audio information at that time will be destroyed, and image noise and audio noise will occur, which may result in serious operation defects. Also, if the hard disk drive breaks due to acceleration exceeding the allowable value when it is not operating,
After moving to the relay point, there may be a fatal defect that the set of the multi video server device 10 does not operate.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a rack mount structure which can reduce transmission of various vibrations when a disk recording / reproducing apparatus is mounted on a rack.

[0015]

According to the present invention, there is provided a disk recording / reproducing apparatus having a plurality of disk media mounted thereon, and a rack in which a plurality of the disk recording / reproducing apparatuses are vertically arranged.

The disc recording / reproducing apparatus is housed in the housing by sliding the inner support on the outer support by putting it on the upper part. In this state, the mounting piece provided on the front surface of the disk recording / reproducing apparatus comes into contact with the mounting member provided on the front surface of the rack, and the mounting member and the mounting member are screwed together, whereby the disk is mounted. Mount the recording / playback device on the rack. By such an operation, the disk recording / reproducing apparatus can be easily mounted.

Since the first buffer means having slidability is arranged between the outer support and the inner support, the outer support and the inner support are connected with the disk recording / reproducing apparatus mounted. Vibrations transmitted between them can be effectively cut off. Therefore, transmission of various vibrations can be reduced, and adverse effects on, for example, a disk drive can be reduced, and stable recording and reproducing operations can be obtained. Further, the inner support can be slid by the outer support by the first buffer means having a slidability, and the inner support can be placed on the outer support to easily insert the disk recording / reproducing apparatus into the rack.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a rack mount structure of a disk recording / reproducing apparatus according to the present invention will be described below. FIGS. 1 to 12 are diagrams showing a rack mount structure according to the present embodiment, and FIGS. 13 to 21 show an outline of a multi-video server device as a disk recording / reproducing device which performs a rack mount according to the present embodiment. FIG.
First, prior to the description of the rack mount structure according to the present embodiment, the configuration of a multi-video server device mounted on a rack according to the present embodiment will be described with reference to FIGS. A multi-video server device according to the present embodiment includes a processor unit that manages overall control of the server device, and a RAID provided with a plurality of disk drives.
And the parts are combined in one housing, and the height of the device housing is suppressed to 220 mm (5 U).

FIG. 13 is a view showing a housing structure of the multi-video server device. FIG. 13 (A) is a plan sectional view, FIG. 13 (B) is a left sectional view, and FIG. 13 (C) is a right sectional view. Figure,
FIG. 13D is a rear view, and FIG. 13E is a front view.
Here, an MPEG server device, which is one type of a multi-video server device, will be described as an example. In the multi-video server device 100, the space in the housing 100 is divided into two parts at the center of the device housing 100A.
A main bus board 105 is provided, and a plurality of hard disk drive units 112 are provided on the front side thereof. Each hard disk drive unit 112
Are housed in the housing 100A in a state of being arranged in the left-right direction. On the back side of the main bus board 105, a plurality of system boards (such as a hard disk control board 110, a recording encoding board 106, and a decoding board 107 for reproduction) are arranged. The system boards 110, 106, 107 and the like are housed in the housing 100A in a state of being horizontally arranged at predetermined intervals vertically.

Hereinafter, the configuration and operation of the multi-video server device 100 will be described in detail. First,
For recording in the multi-video server apparatus 100, a video signal input from an external device is input to the encode board 106, and compression processing is performed. The compressed video signal enters the hard disk control board 110 via the main bus board 105. Therefore, the data is converted into a form suitable for recording on the hard disk drive (101 shown in FIG. 17), and is recorded on the hard disk drive 101 via the hard disk drive interface board 104. On the other hand, in the reproduction of the recorded data, the signal entering the main bus board 105 is decompressed and reproduced by the decode board 107 along the reverse path. And
The system board 109 controls the entire apparatus during such recording and reproduction.

At this time, since the data processing capacity of the hard disk drive, main bus, and the like has room, a plurality of processes can be performed simultaneously. For example, it is possible to play back while recording data, or to play back many places at the same time. In other words, it is possible to perform reproduction while recording, or to reproduce many points at the same time. In the illustrated example, one recording encoding substrate 106 and four decoding decoding substrates 107 are inserted. Also, an interface board 108 is prepared for communication (data) between the apparatuses. These encoding board 106 and decoding board 10
As shown in FIG. 14, a back panel 118 is attached to each of the boards 106, 107, and 108 on the interface board 108 and the like, and a connector 116 required for connection with the outside is mounted on the back panel 118. I have. A connector 120 for connecting each of the boards 106, 107, 108 to the main bus board 105 is directly mounted on an end of each of the boards 106, 107, 108. In this example, the target system can be constructed by freely selecting the types and the number of substrates to be mounted on the device by the number of slots (five in the example shown).

Further, as described above, the main bus board 105 is disposed at the center of the device housing 100A, and the bus line (connection cable 119) is arranged vertically. By doing so, the signal flow coming from the hard disk control board 110 can be placed on the main bus without being bent and routed by 90 degrees, and a clear signal flow can be formed. Further, a main board connected to the main bus board 105 can be arranged horizontally. Assuming that the height of the device housing 100A is 5U, the height of the device housing 100A (5U:
The width (424 mm) is larger than the width (424 mm). Therefore, by arranging the boards 106, 107, and 108 horizontally, a large space for the connectors 116 and 120 to be attached to the boards can be obtained. In particular, in the case of business equipment, it is important to secure an area for a highly reliable connector.

Further, by arranging the substrates 106, 107 and 108 horizontally, a smooth flow of cooling air without stagnation can be realized. As shown in FIG.

FIG. 21 shows the flow of cooling air in the apparatus by such four cooling fans 117. As indicated by the arrow in the figure, the cooling air is sucked in from the front side and the housing 100A
, And absorbs heat and is discharged from the rear side portion of the housing 100A (that is, the fan unit 103). The air absorbed from the front cools the power supply unit 102 and the hard disk drive 101 first.
FIG. 16 shows the appearance of the power supply unit 102. In the power supply unit 102, irregularities are provided on the outer periphery as shown in the figure, so as to increase the heat radiation area. And
The cooling air is guided mainly to the left side of the device at the position of the main bus board 105, and is sent from there to the rear of the device.

Further, in order to increase the reliability of the server device 100, it is necessary to provide redundancy for functional parts having a long life. In this example, the hard disk drive 10
1. The power supply unit 102 and the FAN unit 3 need to have redundancy. In this case, a hot swap that can be replaced without turning off the power and a component replacement in a rack-mounted state must be possible. To replace parts in a rack mounted state,
Alternatively, a structure that allows each component to be inserted and removed from the back surface is required.
