Sled, tray, and shelf assembly for computer data center
An arrangement for mounting and supporting a plurality of cylindrical form or other computer systems, for example Apple Mac Pro cylindrical form computer systems, in a data center so as to optimize cooling air flow, access to cabling, and maximized use of space. A plurality of shelf assemblies is mounted to a computer center rack. Each shelf assembly comprises a tray that supports a pair of slidable sleds. Each sled supports a cylindrical form computer enclosure in an axially horizontal configuration, and includes a sled face that exposes a top surface of a computer enclosure. Air flow perforations in the sled face direct air into the space behind the sled face and across a mounted computer enclosure. The tray and sled provides a convenient arrangement for power and communications cabling, as well as directs a cooling air flow through openings in the trays and sleds upwardly across computer enclosures.
1. A data center mounting rack for mounting and supporting a plurality of special physical form computer enclosures and port expansion chassises in a stacked arrangement, comprising:
a shelving arrangement comprising a plurality of spaced apart vertical end supports supporting a plurality of horizontal mounting trays, each of the horizontal mounting trays supporting at least a pair of computer enclosures;
each of the horizontal mounting trays including one or more rows of first openings positioned at a proximal end of each horizontal mounting tray for permitting cooling air flow in a vertical direction, said first openings positioned in a pair of spaced apart computer enclosure mounting regions positioned immediately below one of said computer enclosures when mounted above the first openings;
each of the horizontal mounting trays including one or more rows of second openings positioned at a distal end of each horizontal mounting tray for allowing the passage therethrough of cabling for computer enclosures when mounted to each said horizontal mounting tray and for permitting cooling air flow in a vertical direction;
a central supporting rib extending along the length of each horizontal mounting tray, dividing the spaced apart computer enclosure mounting regions;
a pair of elongate mounting edge ribs extending along each outer edge of each horizontal mounting tray;
attachment surfaces affixed to each elongate mounting edge rib, for attaching each horizontal mounting tray to the vertical end supports;
at least one slidably-removable horizontal sled for supporting one of said computer enclosures in a slidable arrangement relative to a horizontal mounting tray, each horizontal sled capable of assuming a closed position for operation and an open position positioned outwardly of the proximal end of said horizontal mounting tray to allow access to a supported computer enclosure and/or port expansion chassis mounted to the horizontal sled;
each horizontal sled comprising a generally planar lower surface, a vertically extending sled face at a proximal end that includes an opening for exposing a portion of a supported computer enclosure, a pair of elongate edge ribs extending along the length of each horizontal sled, with a first elongate edge rib including a port connector tab for supporting electrical connectors of one of said port expansion chassises mounted to a horizontal sled; and
each horizontal sled further including a pair of support rails positioned in a central region of the horizontal sled, for supporting one of said computer enclosures and for defining an opening in the horizontal sled that is positioned immediately above the first openings of one of the computer enclosure mounting regions of a horizontal mounting tray when a horizontal sled is in the closed position, for facilitating the flow of air through the first openings and around a supported computer enclosure mounted to the horizontal sled.
2. The data center mounting rack of claim 1 , wherein the special physical form computer enclosures are cylindrical form computer systems.
3. The data center mounting rack of claim 2 , wherein the cylindrical form computer systems are Apple® Mac Pro® brand of cylindrical form computers.
4. The data center mounting rack of claim 2 , wherein each computer enclosure is mounted to a horizontal sled with the central axis of said computer enclosure in a horizontal orientation.
5. The data center mounting rack of claim 1 , wherein the sled face includes plurality of perforated air holes positioned on either side of the opening for allowing the entry of cooling air into a space behind the sled face and directed across a surface of a computer enclosure supported on said horizontal sled.
