Description

  The present invention relates to a storage unit that stores a storage device, and a storage device that stores the storage unit.

  Storage devices equipped with a plurality of storage devices are widely used. Such a storage device is generally called a disk array device. In many cases, since a hard disk drive unit (hereinafter referred to as an HDD unit) is used as a storage device, an HDD unit will be exemplified below as the storage device. FIG. 13 is a perspective view of the storage system 4 including a plurality of disk array devices. The storage system 4 in FIG. 13 has a rack-like main body 40 extending in the vertical direction and a plurality of disk array devices 41 that can be pulled out from the main body 40 in the horizontal direction. A procedure for inserting / removing the HDD unit stored in each disk array device 41 in FIG. 13 will be described with reference to FIGS.

  First, in FIG. 14, the fourth disk array device 41 from the top of the rack-shaped main body 40 is pulled out to the front. As shown in FIG. 14, each disk array device 41 has a box-shaped chassis 410 whose upper part is open, and the upper part of the chassis 410 is closed by a hinge-type top plate 411. The top plate 411 serves as a sealing member that prevents the cooling efficiency of the plurality of HDD units stored inside the chassis 410 from being lowered. That is, outside air does not flow from above into the chassis 410 while the top plate 411 is closed as shown in FIG. 14, so that a flow path for cooling air flowing inside the chassis 410 is appropriately secured. . A blower unit that generates cooling air is disposed inside the chassis 410 adjacent to the storage unit of the HDD unit. The direction of the cooling air flowing inside the chassis 410 is represented by an arrow F14 in FIG. Further, the top plate 411 functions as a shielding member that shields electromagnetic waves generated by the HDD unit in the chassis 410.

  Next, in FIG. 15, the top plate 411 of the chassis 410 is opened. As a result, the upper end of each HDD unit 42 in the chassis 410 is exposed to the outside of the chassis 410. The HDD unit 42 includes an HDD 421 and an active frame 422 that houses the HDD 421, and the upper end of the active frame 422 is exposed outside the chassis 410 in FIG. 15. Thereafter, a desired HDD unit 42 in the chassis 410 is inserted into and removed from the chassis 410 by a maintenance person. However, when the storage system 4 having the above structure is used, it is necessary to secure a space for the top plate 411 to rotate above each chassis 410, so that the space in the installation facility of the storage system 4 can be secured. Cannot be fully utilized. The installation facility of the storage system 4 is, for example, a data center. That is, even if the rack-shaped main body 40 extends near the ceiling of the installation facility, the disk array device 41 cannot be disposed near the ceiling of the installation facility. For this reason, even if the mounting density of the HDD units 42 in each disk array device 41 is large, the mounting density of the HDD units 42 in the entire storage system 4 does not necessarily increase. In addition, when the storage system 4 in FIGS. 14 and 15 is used, the work area of the maintenance person is limited due to the top plate 411 itself. Specifically, when the top plate 411 is opened as shown in FIG. 15, it is difficult for a maintenance person to access each HDD unit 42 from the hinge side of the top plate 411. There is a possibility that the work efficiency of the maintenance person who inserts and removes the lens will be lowered.

  FIG. 16 is a perspective view showing a modified example of the disk array device 41 in FIGS. In the disk array device 41 in FIG. 16, the top plate 411 serving as a sealing member and a shielding member is detachably attached to the chassis 410, so that the above-described problems associated with the handling of the top plate 411 can be solved. . However, when the disk array device 41 in FIG. 16 is used, the gap G between the HDD units 42 stored in the chassis 410 from above is removed from above until the top plate 411 is removed and remounted. Outside air E flows freely. Therefore, the cooling efficiency of the HDD unit 42 in the chassis 410 may be reduced. Further, when the disk array device 41 in FIG. 16 is used, it is necessary to secure an additional space for placing the removed top plate 411. In addition, special care must be taken to ensure that other parts of the storage system 4 are not damaged during the handling of the top plate 411.

  In relation to the above problem, there is known a lock mechanism of a disk array device including a bracket for storing a plurality of HDD units and a lock lever rotatably provided on the bracket (for example, Patent Documents). 1). According to this lock mechanism, the maintenance person uses the lock lever as a handle of the disk array device, so that the disk array device can be easily detached from the housing and carried. Further, there is known a storage housing that includes a front plate including a metal plate and a decorative plate fixed to the metal plate, and stores a box-like drive unit (see, for example, Patent Document 2). According to this storage case, leakage of electromagnetic waves generated inside the storage case can be prevented by the metal plate of the front panel.

JP-A-2005-322306 Japanese Patent Laid-Open No. 7-201163

  However, even if the above-described locking mechanism and storage case are employed in the storage system 4 in FIGS. 14 to 16, outside air can be freely released from above the chassis 410 while the top plate 411 of the disk array device 41 is open. Flow into. The same is true while the top plate 411 is removed from the chassis 410. For this reason, even if the above-described locking mechanism and housing case are operated, it is not possible to properly secure the flow path of the cooling air flowing inside the chassis 410.

  The present application provides a storage unit of a storage device that secures a flow path of cooling air that flows inside the storage device when a plurality of storage devices are stored in the storage device, and a storage device including the storage unit. The purpose is to provide.

  According to one aspect of the embodiment, a storage unit that stores a storage device and supports the storage device in an active state in the storage device, the main body unit to which the storage device is attached, and the main body engaged with the storage device An engaging portion provided at one end of the storage portion, and the engaging portion can be projected and retracted with respect to the exposed end of the engaging portion exposed to the outside of the storage device when the storage unit is inserted into the storage device. When the first movable portion and the storage unit are inserted into the storage device, the first movable portion is adjacent to one of the side surfaces contacting the exposed end of the engaging portion in conjunction with the immersion of the first movable portion into the engaging portion. And a second movable part projecting toward the inner wall surface of the other storage unit or storage device, and the second movable part becomes a second movable part when the second movable part projects. The airflow that flows toward Is formed in a shape to harm, housing unit is provided.

  According to the disclosed storage unit, the flow path of the cooling air flowing inside the storage device can be secured without providing a sealing member such as a top plate for sealing the storage device on the storage device side.

  Hereinafter, embodiments of a storage unit and a storage device according to the present application will be described in detail with reference to the accompanying drawings based on specific examples. In the embodiments described below, a disk array device in which a plurality of HDD units are mounted is illustrated as a storage device according to the present application. However, the storage device according to the present application is another storage device having the same structure as the above disk array device, for example, a storage device equipped with a plurality of optical disk drive units or a plurality of solid state drive (SSD) units. May be.

  FIG. 1A is a perspective view of a disk array device 1 to which the storage unit of the first embodiment of the present application is applied. As shown in FIG. 1A, the disk array device 1 includes a box-shaped chassis 10 having an open top, and a plurality of HDD units 2 stored inside the chassis 10 so as to be insertable / removable. The chassis 10 includes a left side wall W1 and a right side wall W2 facing each other, a front wall W3 that intersects each of the left side wall W1 and the right side wall W2, and a rear wall W4 that intersects each of the left side wall W1 and the right side wall W2. And a rear portion 11 including. A cooling fan unit (not shown) is built in the rear portion 11 of the chassis 10. The cooling fan unit generates cooling air that flows from the front wall W3 toward the rear wall W4 inside the chassis 10. The direction of the cooling air flowing inside the chassis 10 is indicated by an arrow F1 in FIG. 1A (the same applies to FIGS. 1B and 1C). However, the cooling fan unit can also generate cooling air in the direction opposite to the arrow F1 in FIG. 1A. In addition to the cooling fan unit, the rear portion 11 of the chassis 10 incorporates a control unit, a power supply unit, and the like.

  FIG. 1B is a perspective view similar to FIG. 1A and shows a state in which only one of the plurality of HDD units 2 is removed from the chassis 10. As shown in FIG. 1B, the individual HDD units 2 are arranged in a vertical orientation with respect to the chassis 10. The individual HDD units 2 are stored inside the chassis 10 while being stored in the storage unit 3. The storage unit 3 serves to support the HDD unit 2 stored in the chassis 10 in an active state with respect to the chassis 10. The active state here means a state where a flow path of cooling air flowing inside the chassis 10 is secured, that is, a state where the cooling air flowing inside the chassis 10 is not blocked by the storage unit 3. Further, the storage unit 3 plays a role of assisting a user to insert and remove the HDD unit 2 from the chassis 10 for maintenance or repair of the HDD unit 2. Specifically, the user can easily insert and remove the HDD unit 2 stored in the storage unit 3 from the chassis 10 by holding the handle 33 of the storage unit 3. The storage unit 3 can also store a dummy member having the same outer dimensions as the HDD unit 2 instead of the HDD unit 2.

  Next, the arrangement of the plurality of HDD units 2 in the disk array device 1 will be described. In the following description, the direction in which the left side wall W1 and the right side wall W2 are aligned is referred to as the left-right direction of the chassis 10, and the direction in which the front wall W3 and the rear wall W3 are aligned is referred to as the front-rear direction of the chassis 10. A direction perpendicular to both the left-right direction and the front-rear direction of the chassis 10 is referred to as the up-down direction of the chassis 10. 1A to 1C, the left-right direction, the front-rear direction, and the up-down direction of the chassis 10 are represented by arrows D11, D12, and D13, respectively (the same applies to other drawings). As shown in FIGS. 1A and 1B, the disk array device 1 stores a plurality of HDD units 2 arranged in four rows in the front-rear direction of the chassis 10. Each column in the front-rear direction of the chassis 10 includes 12 HDD units 2, so the disk array device 1 can store a maximum of 48 HDD units 2. In the following description, each of the rows of HDD units 2 arranged in the front-rear direction of the chassis 10 may be simply referred to as an HDD row.

  FIG. 1C is a perspective view similar to FIGS. 1A and 1B, and includes a cross section of the disk array device 1 perpendicular to the front-rear direction of the chassis 10. As shown in FIG. 1C, twelve HDD units 2 included in each HDD row are arranged at intervals in the left-right direction of the chassis 10. That is, when a plurality of HDD units 2 are stored in the chassis 10, a ventilation path P extending in the front-rear direction of the chassis 10 is formed between the HDD units 2 adjacent in the left-right direction of the chassis 10. The ventilation path P is also formed between the left side wall W1 of the chassis 10 and the HDD unit 2 located at the left end of each HDD row, and the HDD unit located at the right side wall W2 of the chassis 10 and the right end of each HDD row. 2 is also formed. As described above, the HDD unit 2 included in each HDD row is supported in the active state in the chassis 10.

  FIG. 2 is a perspective view showing only the chassis 10 of the disk array device 1 in FIGS. 1A to 1C. As shown in FIG. 2, four partition walls 12 extending in parallel with the front wall W <b> 3 are installed in the interior space of the chassis 10 in which the HDD unit 2 is stored with a space in the front-rear direction of the chassis 10. Since these partition walls 12 extend from the left side wall W <b> 1 to the right side wall W <b> 2, the internal space of the chassis 10 is divided by the partition walls 12 into four small rooms C aligned in the front-rear direction of the chassis 10. In each small room C, each HDD row is stored. Hereinafter, the space in the small room C in which the individual HDD units 2 are stored is particularly referred to as a slot S (see FIG. 1C).

  As shown in FIG. 2, each partition wall 12 is provided with a plurality of vent holes H arranged at intervals in the left-right direction of the chassis 10. The plurality of vent holes H are constituted by two rows arranged in the vertical direction of the chassis 10. Each vent hole H is arranged so as to communicate two ventilation paths P located on both sides of the partition wall 12 when the HDD row is stored in each small room C. Therefore, the cooling air flowing in the front-rear direction of the chassis 10 through the ventilation path P is not blocked by the partition wall 12. The upper end surface 12 a of the partition wall 12 is formed from a plate-like gasket that extends in the left-right direction of the chassis 10. The gasket is an example of a sealing member. A plurality of fixing protrusions 13 for fixing each storage unit 3 to the chassis 10 are provided on the front and rear surfaces of the partition wall 12. These fixing protrusions 13 are arranged at intervals along the upper end surface 12 a of the partition wall 12. The operation of the fixing protrusion 13 will be described later.

  Next, the structure of the storage unit 3 will be described. FIG. 3 is a perspective view showing the storage unit 3 in a state where the HDD unit 2 is stored. For convenience, a part of the chassis 10 is shown together with the storage unit 3 in FIG. As shown in FIG. 3, the storage unit 3 includes an active frame 31 to which the HDD unit 2 is attached, and an engaging portion 32 provided at one end of the active frame 31 so as to engage with the partition wall 12 of the chassis 10. doing. The active frame 31 is an example of the main body of the storage unit 3 to which the HDD unit 2 is attached. Further, the engaging portion 32 incorporates a handle 33 and a slider 34 that are movable in predetermined directions. The handle 33 is an example of a first movable part of the storage unit 3, and the slider 34 is an example of a second movable part of the storage unit 3. The structure of the active frame 31 and the engaging portion 32 will be described in detail below.

  FIG. 4A is a perspective view showing the storage unit 3 with the HDD unit 2 removed. 4B is an exploded perspective view corresponding to FIG. 4A. As shown in FIG. 4A, the active frame 31 of the storage unit 3 has an overall shape of an inverted U shape that can store the HDD unit 2 in a vertically oriented posture from above. Specifically, the active frame 31 includes a plate-like base portion 311 and a pair of plate-like sandwiching portions 312 that protrude perpendicularly to the base portion 311 from both longitudinal ends of the base portion 311. The base 311 has a longitudinal dimension that is smaller than the distance between adjacent partition walls 12. Therefore, when the entire storage unit 3 is stored in the chassis 10, the base portion 311 and the sandwiching portion 312 are disposed between the adjacent partition walls 12 in the chassis 10.

  In addition, the pair of sandwiching portions 312 is formed so as to sandwich the pair of side surfaces of the HDD unit 2 from the side (see FIG. 3). The pair of sandwiching portions 312 preferably have a protruding length that is approximately the same as the entire length of the HDD unit 2 in a vertically oriented posture. Thereby, each clamping unit 312 can clamp the HDD unit 2 over the entire length of the HDD unit 2. In the following description, the extending direction of the base portion 311 is referred to as the left-right direction of the storage unit 3, and the protruding direction of the clamping portion 312 is referred to as the up-down direction of the storage unit 3. A direction perpendicular to both the left-right direction and the front-rear direction of the storage unit 3 is referred to as the front-rear direction of the storage unit 3. In FIG. 4A, the left-right direction, the front-rear direction, and the left-right direction of the storage unit 3 are represented by arrows D21, D22, and 23, respectively (the same applies to other drawings).

  As shown in FIGS. 4A and 4B, the engaging portion 32 of the storage unit 3 includes a wall-like portion 320 standing on the upper surface of the base portion 311 of the active frame 31 and a plate-like portion attached to the upper end of the wall-like portion 320. And a lid portion 323. As shown in FIG. 4B, the wall portion 320 of the engaging portion 32 is formed integrally with the base portion 311 of the active frame 31, and a pair of side wall portions 321 projecting in the opposite direction of the clamping portion 312 from the upper surface of the base portion 311. And a rear wall portion 322 extending between the rear end portions of the pair of side wall portions 321. As shown in FIG. 4B, the front end surface 321 a of each side wall portion 321 is located behind the front end surface 311 a of the base portion 311. A movable slider 34 is disposed in front of the front end surface 321a of each side wall portion 321, and the front end surface 321a of each side wall portion 321 is formed to stop the slider 34 at a retracted position described later. Yes.

  As shown in FIG. 4A, the lid portion 323 of the engaging portion 32 has a pair of overhang portions 323 a that overhang both sides of the active frame 31 in the left-right direction of the storage unit 3. The dimension in the left-right direction of the entire lid portion 323 including the pair of overhang portions 323a is made larger than the distance between adjacent partition walls 12 in the chassis 10. Therefore, when the storage unit 3 is stored in the chassis 10, the wall portion 320 is disposed between the two partition walls 12 together with the active frame 31, but the lid portion 323 is disposed at the upper ends of the two partition walls 12. It is bridged. That is, when the storage unit 3 is stored in the chassis 10, the upper surface of the lid portion 323 forms an exposed end of the storage unit 3 that is exposed to the outside of the chassis 10.

  As shown in FIG. 4B, the lid 323 has a through-type slit 323 b that extends in the left-right direction of the storage unit 3. A movable handle 33 is inserted into the slit 323b of the lid 323, and the inner peripheral surface of the slit 323b is formed so as to guide the vertical movement of the handle 33. On the upper surface of the lid portion 323, a pair of notch portions 323c for assisting the user to grip the handle 33 is further provided. The pair of notch portions 323c are arranged so as to sandwich the slit 323b2 in the front-rear direction of the storage unit 3, and each of the notch portions 323c has a curved shape that can accommodate the fingertip of the user. . Since the internal space of the notch 323c communicates with the internal space of the slit 323b, the user can easily grasp the handle 33 by putting the fingertip into the notch 323c.

  As illustrated in FIG. 4B, the storage unit 3 further includes a plate-shaped shielding member 35 disposed below the lid portion 323. The shielding member 35 plays a role of blocking electromagnetic waves emitted from the HDD unit 2 and directed to the lid portion 323. As a result, it is possible to reduce the leakage of electromagnetic waves that leak to the outside of the chassis 10 during operation of the disk array device 1. The shielding member 35 is formed of, for example, various metal plates that shield electromagnetic waves, and is attached to the lower surface of the base 311 by a base 311 and a bolt 324 that connects the wall-shaped part 320 and the lid 323.

  The handle 33 and the slider 34 of the storage unit 3 will be described with reference to FIGS. 4A and 4B. The handle 33 of the storage unit 3 is incorporated in the engaging portion 32 so as to be able to protrude and retract with respect to the upper surface of the lid portion 323. As shown in FIG. 4B, the handle 33 has a plate-like overall shape extending in the left-right direction of the storage unit 3, and is guided to the inner peripheral surface of the slit 323b of the lid portion 323 so that the handle 33 has a predetermined upper position and a lower position. It can move back and forth between positions. FIG. 4A shows the handle 33 in the upper position. A groove 33 a is provided at the upper end of the handle 33 to assist the user in gripping the handle 33. The groove 33 a extends in the left-right direction of the storage unit 3 and is provided on both the front surface and the rear surface of the handle 33. As shown in FIG. 4A, the groove 33 a on each surface of the handle 33 is disposed so as to face the notch 323 c of the lid 323. Therefore, the user can easily grasp the handle 33 by hooking the fingertip on the groove 33 a of the handle 33. In addition, it is preferable that at least a part of the outer peripheral surface of the handle 33 guided to the inner peripheral surface of the slit 323b is formed of a gasket that can be hermetically contacted with the inner peripheral surface of the slit 323b. The gasket is an example of a sealing member. Thereby, the sealing performance between the outer peripheral surface of the handle 33 and the inner peripheral surface of the slit 323b can be improved.

  In addition, the slider 34 of the storage unit 3 moves from one of the side surfaces of the engaging portion 32 that intersects the upper surface of the lid portion 323 in conjunction with the immersion of the handle 33 into the engaging portion 32. It is formed so as to protrude outward. Therefore, when the entire storage unit 3 is stored in the chassis 10, the slider 34 of the storage unit 3 can protrude toward another storage unit 3 adjacent to the chassis 10 in the left-right direction. As a result, the airflow flowing in the vertical direction of the chassis 10 toward the slider 34 is hindered, so that the inflow of outside air to the ventilation path P between two adjacent storage units 3 is reduced or prevented (see FIG. 1C). ). As a result, since the airtightness of the ventilation path P in the vertical direction of the chassis 10 is improved, a flow path for cooling air flowing in the front-rear direction in the chassis 10 is secured. As shown in FIG. 4B, the slider 34 has a rectangular bar-like overall shape extending in the left-right direction of the storage unit 3, and is guided to both the lower surface of the lid portion 323 and the upper surface of the base portion 311, thereby causing a predetermined protrusion. It can reciprocate between the position and the retracted position. FIG. 4A shows the slider 34 in the retracted position.

  In addition, it is preferable that the square bar shape of the slider 34 has a length comparable to the dimension of the wall-shaped part 320 in the left-right direction of the storage unit 3. Thereby, since the airflow flowing in the vertical direction of the chassis 10 is hindered over the entire length of the storage unit 3 in the horizontal direction, the sealing performance of the ventilation path P in the vertical direction of the chassis 10 can be further improved. Further, the front end surface 34 a in the protruding direction of the slider 34 is preferably formed from a plate-like gasket extending in the left-right direction of the storage unit 3. The gasket is an example of a sealing member. Thus, when the slider 34 protrudes, the front end surface 34a of the slider 34 comes into airtight contact with the rear wall portion 322 'of the other storage unit 3' adjacent in the chassis 10 (which will be described later with reference to FIG. 11C).

  Next, the interlocking mechanism between the handle 33 and the slider 34 of the storage unit 3 will be described. FIG. 5A is a perspective view showing the storage unit 3 when the handle 33 is in the upper position. FIG. 5A includes a cross section perpendicular to the left-right direction of the storage unit 3. The cross section in FIG. 5A is obtained by cutting the central portion of the engaging portion 32 from which the handle 33 extends. FIG. 5B is a cross-sectional view of the storage unit 3 corresponding to FIG. 5A. As shown in FIG. 5B, the lower end portion of the handle 33 is provided with an inclined surface 33I inclined downward toward the rear end portion of the slider 34, and the lower end portion of the handle 33 is provided at the rear end portion of the slider 34. An inclined surface 34I inclined upward is provided. The inclined surfaces 33I and 34I of the handle 33 and the slider 34 are formed so as to convert the movement of the handle 33 from the upper position to the lower position into the movement of the slider 34 from the retracted position to the protruding position by sliding contact with each other. Has been. Therefore, when the handle 33 located at the upper position is pushed downward by the user, the slider 34 located at the retracted position is moved outward from the engaging portion 32 toward the protruding position.

  The lower end portion of the handle 33 is provided with a vertical surface 33V that is continuous with the inclined surface 33I and perpendicular to the moving direction of the slider 34, and the rear end portion of the slider 34 has the inclined surface 34I. And a vertical surface 34V perpendicular to the moving direction of the slider 34 is provided. FIG. 6A is a perspective view showing the storage unit 3 when the handle 33 is in the lower position. 6A includes a cross section perpendicular to the left-right direction of the storage unit 3 as in FIG. 5A. 6B is a cross-sectional view of the storage unit 3 corresponding to FIG. 6A. As shown in FIGS. 6A and 6B, the vertical surfaces 33V and 34V of the handle 33 and the slider 34 come into surface contact with each other after the sliding contact between the inclined surfaces 33I and 34I, so that the slider 34 moves from the protruding position to the retracted position. It is formed to prevent it from moving. That is, the slider 34 is locked at the protruding position by the vertical surface 33V of the handle 33 after the sliding contact between the inclined surfaces 33I and 34I is completed. Therefore, even if the slider 34 in the protruding position is pushed backward toward the retracted position, the slider 34 does not move toward the retracted position.

  Referring to the exploded perspective view of FIG. 4B again, the engaging portion 32 of the storage unit 3 further includes a tension spring 36 attached to the rear surface of the slider 34. The tension spring 35 is an example of an urging member and constantly urges the slider 34 toward the retracted position. FIG. 7A is a perspective view showing the storage unit 3 when the slider 34 is in the retracted position. FIG. 7A includes a cross section perpendicular to the left-right direction of the storage unit 3 as in FIG. 6A. However, the cross section in FIG. 7 is obtained by cutting a side portion of the engaging portion 32 where the handle 33 does not extend. FIG. 7B is a cross-sectional view of the storage unit 3 corresponding to FIG. 7A. As shown in FIGS. 7A and 7B, one end of the tension spring 36 is attached to the rear surface of the slider 34, and the other end of the tension spring 35 is attached to the rear wall portion 322 of the engaging portion 32 facing the rear surface of the slider 34. It is attached. Therefore, the slider 34 is always urged rearward toward the rear wall portion 322 regardless of its position. However, since the engaging portion 32 further includes a side wall portion 321 that stops the slider 34 at the retracted position, the slider 34 does not move further backward from the retracted position (see FIGS. 4B and 6B).

  Referring to FIGS. 5B and 6B again, the operation of the slider 34 while the handle 33 is pulled up from the lower position in FIG. 6B to the upper position in FIG. 5B will be described. First, until the handle 33 reaches a predetermined height position, the vertical surface 33V of the handle 33 and the vertical surface 34V of the slider 34 only make sliding contact in the vertical direction, so that the slider 34 is retracted from the protruding position. Never move towards. That is, the slider 34 is locked by the vertical surface 33V of the handle 33. Thereafter, when the sliding contact between the two vertical surfaces 33V and 34V is completed, the inclined surface 33I of the handle 33 and the inclined surface 34I of the slider 34 start the sliding contact in the oblique direction. As a result, the locked state of the slider 34 is released, and as the handle 33 is further pulled up, the slider 34 moves to the rear wall 322 side by the action of the tension spring 36. Thereafter, when the rear surface of the slider 34 comes into contact with the side wall 321 and stops, the movement of the slider 34 from the protruding position to the retracted position is completed.

  Here, a modified example of the interlocking mechanism of the handle 33 and the slider 34 in the storage unit 3 will be described. 8 and 9 are cross-sectional views perpendicular to the left-right direction of the storage unit 3 in which the interlocking mechanism of this example is employed. 8 shows the storage unit 3 when the handle 33 is in the upper position as in FIG. 5B, and FIG. 9 shows the storage unit 3 when the handle 33 is in the lower position as in FIG. 6B. Yes. As shown in FIGS. 8 and 9, the storage unit 3 according to this example further includes a link 37 that is rotatably connected to each of the lower end portion of the handle 33 and the rear end portion of the slider 34. The link 37 is rotatable about a first rotation axis R1 provided at the lower end of the handle 33, and is rotated about a second rotation axis R2 provided at the rear end of the slider 34. It is possible to move.

  FIG. 10 is a perspective view showing only the handle 33, the slider 34, and the link 37 in FIG. As shown in FIG. 10, one link 37 is provided on each side of the handle 33 in the left-right direction of the storage unit 3. Further, the two rotation shafts R <b> 1 and R <b> 2 of the link 37 extend parallel to the left-right direction of the storage unit 3. The handle 33 and the slider 34 of the storage unit 3 according to this example have the same structure as that of the handle 33 and the slider 34 shown in FIGS. Further, the active frame 31 and the engaging portion 32 of the storage unit 3 according to this example have the same structure as the active frame 31 and the engaging portion 32 shown in FIGS. 4A to 7B.

  As shown in FIGS. 8 and 9, the link 37 is formed to convert the movement of the handle 33 from the upper position to the lower position into the movement of the slider 34 from the retracted position to the protruding position. Specifically, when the handle 33 moves from the upper position toward the lower position, the link 37 rotates about the first rotation axis A1 in the direction of the arrow D81 in FIG. Is pivoted in the direction of arrow A82 in FIG. As a result, the slider 34 is pushed from the retracted position toward the protruding position. When the slider 34 reaches the protruding position, the two rotation axes R1 and R2 of the link 37 are aligned on a virtual plane perpendicular to the vertical direction of the storage unit 3. This imaginary plane is represented by a chain line in FIG. In this state, the link 37 does not rotate even when the slider 34 is pushed toward the retracted position. That is, the slider 34 is locked at the protruding position.

  On the other hand, when the handle 33 moves from the lower position toward the upper position, the link 37 rotates about the first rotation axis A1 in the direction of the arrow D91 in FIG. 9, and the second rotation axis. It rotates about A2 in the direction of arrow A92 in FIG. As a result, the slider 34 is pulled toward the retracted position. As described above, in the storage unit 3 of this example, the movement of the handle 33 toward the lower position is converted into the movement of the slider 34 toward the protruding position by the rotation of the link 37. It is not necessary to provide 34I on the handle 33 and the slider 34. In the storage unit 3 of this example, the movement of the handle 33 toward the upper position is converted into the movement of the slider 34 toward the retracted position by the rotation of the link 37, so that the tension spring 36 is moved to the slider 34. There is no need to install.

  Next, a procedure for mounting the storage unit 3 to the chassis 10 of the disk array device 1 will be described with reference to FIGS. 11A to 11C. First, in this procedure, the storage unit 3 storing the HDD unit 2 is positioned above the corresponding slot S of the chassis 10. At that time, the storage unit 3 is maintained in a posture in which the vertical direction is parallel to the vertical direction of the chassis 10 and the front-back direction is parallel to the horizontal direction of the chassis 10. The storage unit 3 positioned above the slot S in such a posture is shown in FIG. 1B. Next, the storage unit 3 is inserted into the corresponding slot S with the above posture. As shown in FIG. 1B, it is assumed that another storage unit 3 is inserted in advance in a slot S adjacent to the slot S in which the storage unit 3 is inserted.

  11A to 11C are enlarged cross-sectional views of the chassis 10 perpendicular to the left-right direction. FIG. 11A to FIG. 11C show, in chronological order, a procedure for mounting the storage unit 3 storing the HDD 2 to the chassis 10. First, at the time of FIG. 11A, the storage unit 3 is partially inserted into the slot S in the chassis 10. As shown in FIG. 11A, while the storage unit 3 is inserted into the slot S, the handle 33 is maintained at the upper position, so that the slider 34 is maintained at the retracted position. This prevents the slider 34 of the storage unit 3 from interfering with other storage units 3 ′ in the chassis 10. Next, at the time of FIG. 11B, the storage unit 3 is completely inserted into the slot S. At the same time, the connector on the lower surface side of the HDD 2 is fitted into the connector on the bottom surface B side of the chassis 10.

  As shown in FIGS. 11A and 11B, while the storage unit 3 is inserted into the slot S, the slider 34 ″ of the storage unit 3 ″ adjacent to the right side of the HDD 2 or the rear wall 322 of the storage unit 3 comes into airtight contact. doing. As a result, the ventilation path P between the storage unit 3 being inserted and the storage unit 3 ″ adjacent to the right side is sealed in the vertical direction of the chassis 10, thus preventing inflow of outside air into the ventilation path P. 11B, since the slider 34 of the storage unit 3 being inserted is still in the retracted position, the ventilation path between the storage unit 3 being inserted and the storage unit 3 ′ adjacent to the left side is provided. P remains open in the vertical direction of the chassis 10. Note that when the storage unit 3 is completely inserted into the slot S as shown in Fig. 11B, the lower surface of the overhanging portion 323a of the storage unit 3 is separated from the partition wall 12. (See FIGS. 2 and 4A.) As a result, the inflow of outside air into the chassis 10 is accommodated in the front-rear direction of the chassis 10. It may be blocking on both sides.

  11C, the handle 33 of the storage unit 3 is pushed down from the upper position to the lower position. As a result, the slider 34 of the storage unit 3 is pushed out from the retracted position to the protruding position, so that the front end surface 34a of the slider 34 comes into contact with the rear wall portion 322 'adjacent to the left side. As a result, since the front end surface 34a of the slider 34 comes into airtight contact with the rear wall portion 322 ′ of the adjacent storage unit 3 ′, the air passage P between the two storage units 3 and 3 ′ is also in the vertical direction of the chassis 10. Sealed. That is, the inflow of outside air into the chassis 10 can be prevented on both sides of the storage unit 3 in the left-right direction of the chassis 10. This completes the procedure for mounting the storage unit 3 to the chassis 10.

  In the state shown in FIG. 11C, since the slider 34 has completely entered the lower side of the fixed protrusion 13 of the chassis 10, the storage unit 3 cannot move in the vertical direction with respect to the chassis 10. That is, the storage unit 3 is locked by the fixing protrusion 13 so as not to be taken out from the chassis 10. Therefore, in order to take out the storage unit 3 once mounted on the chassis 10, it is necessary to move the slider 34 from the protruding position to the retracted position by pulling the handle 33 upward. As a result, the locked state of the storage unit 3 is released, so that the storage unit 3 can be detached from the chassis 10 by pulling the handle 33 further upward.

  As described above, in the disk array device 1 according to the present embodiment, the slider 34 of the storage unit 3 projects to the other storage unit 3 'side in conjunction with the handle 33, thereby forming a sealed state in the vertical direction of the chassis 10. (See particularly FIG. 11C). However, since there is no other storage unit between the storage unit 3 located at the left end of each HDD row in the chassis 10 and the left side wall W1, the storage unit 3 located at the left end of each HDD row is the other storage unit. It protrudes toward the left side wall W1 instead of the unit (see FIGS. 1A to 1C). Therefore, it is preferable that the left side wall W <b> 1 of the chassis 10 is provided with a first contact structure portion that can come into airtight contact with the front end surface 34 a of the slider 34. Similarly, there is no other storage unit between the storage unit 3 located at the right end of each HDD row in the chassis 10 and the right side wall W2. Therefore, it is preferable that the right side wall W <b> 2 of the chassis 10 is provided with a second close contact structure portion that can come into airtight contact with the rear wall portion 322 of the storage unit 3.

  FIG. 12A is a perspective view showing a modified example of the chassis 10 provided with the first and second dense structures. 12B is a cross-sectional view perpendicular to the front-rear direction of the chassis 10 in FIG. 12A. As shown in FIGS. 12A and 12B, a groove portion 14 extending in the front-rear direction of the chassis 10 is provided on the inner wall surface of the left side wall W1. The groove part 14 is an example of a first adhesion structure part. Specifically, the groove portion 14 of the side wall W1 has a dimension capable of receiving the slider 34 at the protruding position. The bottom surface of the groove 14 is formed so as to be in close contact with the front end surface 34a of the slider 34 located at the protruding position. Thereby, not only the ventilation path P between the adjacent storage units 3 but also the ventilation path P between the left side wall W1 and the storage unit 3 is sealed in the vertical direction of the chassis 10, so Sealability can be further improved. Note that, depending on the positional relationship between the left side wall W1 and the storage unit 3, a close contact structure portion different from the groove portion 14 in FIGS. 12A and 12B may be employed. For example, when the distance between the left side wall W1 and the storage unit 3 is relatively large, a ridge-shaped structure portion extending in the front-rear direction of the chassis 10 is provided on the inner wall surface of the left side wall W1.

  FIG. 12C is a perspective view of the chassis 10 in FIG. 12B viewed in another direction. As shown in FIG. 12C, the chassis 10 of this example further includes a ridge-shaped raised portion 15 provided on the inner wall surface of the right side wall W2. The raised portion 15 is an example of a second adhesion structure portion. More specifically, the raised portion 15 is formed of a square bar-like sealing member extending in the front-rear direction of the chassis 10. The front end surface of the raised portion 15 in the raised direction is formed so as to be in airtight contact with the rear wall portion 322 of the storage unit 3. Thereby, not only the ventilation path P between the adjacent storage units 3 but also the ventilation path P between the right side wall W2 and the storage unit 3 is sealed in the vertical direction of the chassis 10, so Sealability can be further improved.
