Description

  The present invention relates to a reader / writer mounting technique in a rack system that efficiently reads an electronic tag (non-contact IC (Integrated Circuit) tag or wireless tag) mounted on a rack-mounted device.

  In recent years, a rack mount system in which electronic devices such as servers and disk array devices are mounted on a rack to save space has become widespread.

  The rack on which the rack-mounted device is mounted has a fixed mounting pitch. In the case of a general 19-inch rack, the minimum mounting pitch is 1U = 44.45 mm. One rack mount device is attached in the range of an integral multiple of 1U.

  Multiple devices with the same appearance may be mounted in the rack. Knowing not only in which rack the target device is mounted, but also in which slot, the target device Mistakes such as mistakes can be reduced.

  In a data center or the like where a large number of rack mount devices are installed, when performing inventory or product maintenance, it has been confirmed that the target device is actually there. In addition, when a device is shipped in a rack at the factory, the method of checking whether the specified rack mounting pattern is the same as the actual rack mounting pattern is generally a method that is confirmed by human inspection. It was a very complicated task.

  To deal with these problems, a method of managing devices mounted in a rack by using a generally known electronic tag can be considered.

  When applying a technology for reading electronic tags to a rack mount system, it is generally considered that an electronic tag is attached to a device such as a rack mount server or disk array device mounted in a rack, and a reader / writer is attached to the rack. . Further, in order to confirm what device is installed in which slot (storage position) of the rack, it is conceivable to install a reader / writer in each slot.

  However, at this time, if the distance between the electronic tag and the reader / writer is long, (1) the distance between the electronic tag and the reader / writer becomes long, a powerful reader / writer is required, and the cost increases. (2) Reader If the reception range of the writer is expanded, problems such as picking up radio waves from the electronic tags of devices mounted in other slots and reducing the reliability of reading occur.

  In addition, when the front side (rack front side) or back side (rack rear side) of the device is used as a common location for attaching an electronic tag to a rack mount device, the rack door is used as the reader / writer attachment location. Can be considered. However, since the rack front and rear areas are usually used for cable processing, when the door is closed after cable processing, the reader / writer installed on the door interferes with the cable.

  Conventionally, a method has been proposed in which an electronic tag is attached to a shelf member installed in a shelf shape, and a reader / writer is attached to a housing portion in which the shelf is accommodated (see Patent Document 1). As the position of the reader / writer attached to the accommodating portion, the reader / writer is installed within the range occupied when the shelf member having the same shape is accommodated.

  However, when the above technique is applied to a rack mount system in which various devices with different depths are mounted, the following two points can be considered as attachment positions of the reader / writer. One is the position facing the front of the device attached to the front column of the rack, and the other is the part near the front column of the rack on the side of the rack. In connection with cable processing, there is a problem in the installation and maintainability of the device.

In addition, when mounting on the side surface of the rack, it is possible to cope with a device having a short depth as long as the portion is close to the support on the front side of the rack, but a problem peculiar to the rack system occurs. In rack systems, when mounting equipment in a rack, it is common to mount mounting brackets across the front column of the rack or across the front and rear columns, and then mount the product on the brackets. The mounting bracket enters between the electronic tag mounted on the rack mount apparatus and the reader / writer mounted on the rack. In particular, in the 1U rack mount type apparatus, the side surface of the apparatus may be occupied by the slide rail, and an electronic tag is attached to the rack mount type apparatus in a region between the front side support column and the back side support column of the rack to which the slide rail is attached. It is difficult to attach.
