Rack server, rack mount computer server

Electronic devices such as computer components are often stored in an electronic rack system. A variety of different computer components including servers, computers, storage devices such as disk drives, and RAID drives, as well as other electrical devices can be housed in rack systems. The Electronic Institute of America (EIA) has defined a standard for mounting electronic equipment that has been widely adopted among the industry standard server marketplace. Industry standard 19" EIA electronics racks are designed typically to house a column of electronics packages that are 17-3/4" in width with varying depths. The height of an electronics package can vary but is normally an integer multiple of an EIA unit called simply the "U." A mounting unit or U is typically 1.75 inches. Interior rails of rack systems often have three mounting slots selectively spaced within each U of vertical space for attaching components. Rack systems and components are typically sized in mounting unit increments. Typically, electronic components may be secured within the rack using a pair of rack rails that are secured to the rack structure. These rails may fix the component in place or support sliding mechanisms that enable the component to be easily moved in and out of the rack. In order to accommodate the many different types of equipment that may be mounted within a particular rack-mount chassis, the rack-mount chassis may have a large number of holes drilled in its bottom panel. A rack-mount chassis installed within a rack may be utilized to hold server computers, mass storage devices, telecommunications equipment, and a wide variety of other types of electronic equipment. Rack mount servers provide an effective way of aggregating a large number of servers, and thus storage capacity, in a relatively small space.
