Description

The present invention relates to a ceiling-suspended server rack that can be installed on the ceiling, and even if the indoor space is limited, it is possible to rationally accommodate a plurality of rack servers and electronic devices. Regarding the rack.

A server rack is a generic term for a rack or cabinet that houses electronic devices such as servers. In the current server rack, not only servers but also various IT equipment such as routers and switches and information equipment are stored.

Patent Document 1 describes a server storage rack that is an improved 19-inch rack. This server storage rack is a 19-inch rack with various sensors and antistatic measures.

As a server used in general offices and homes, a server having a shape similar to a desktop main body called a tower server is mainly used. On the other hand, thin and flat stackable servers called rack servers are used for many servers used in network centers and the like. To store the rack server, a so-called 19-inch rack in which the mount angle for fixing the rack server is standardized is used.

The 19-inch rack is a rack whose specifications of mount angles for mainly fixing rack servers are standardized, and is configured so that various devices can be reasonably stored in a common mount angle. And the basic dimensions of a server rack equipped with this standard mount angle are, for example, the IEC standard (IEC 60297-3-100) and the various basic dimensions of the 19-inch series front panel, subrack, chassis, rack and cabinet. It is shown. Similar standards are also shown in JIS standards (JIS C 6012-3-100).

Further, various IT devices such as routers and switches, information devices, etc. are often manufactured so as to be mounted on the 19-inch rack. Therefore, along with the rack server, most of various IT equipments are reasonably stored in this 19-inch rack.

Servers and IT equipment are now widely used in stores and the like. Moreover, in a chain store that connects a plurality of stores, each store is connected to a network, and a server or router for each store is also used. Therefore, in such a chain store, it is possible to rationalize the work by using the rack server rather than the tower server.

However, in some cases, even if the chain stores are large in scale, each store becomes a small store with a limited floor space. If a rack server is used in such a small store, it may be difficult to secure a space for the server rack. In other words, a floor area of at least 600 mm in width and 600 mm in depth is required to install a general 19-inch rack that houses a rack server. Moreover, since a large number of cords are wired to the rack server, IT equipment, etc., it is necessary to secure a wiring space in addition to the rack installation space.
