Rack diagram (RackDiag)

RackDiag draws a rack elevation from a list of units. Multi-unit equipment declares a span, and the empty units stay visible, which is the point.

#What this example shows

• Rack height declared once at the top.

• Equipment placed at a unit number, with a span.

• Descriptions carrying the model.

The source, which you can paste into a new diagram and edit:

rackdiag {
  24U;
  1: UPS [2U, description = "APC SMT3000"];
  3: PDU;
  4: Patch panel A [description = "1-24"];
  5: Patch panel B [description = "25-48"];
  6: Core switch [description = "48 port, 10G uplinks"];
  7: ToR switch;
  9: App server 01 [2U];
  11: App server 02 [2U];
  13: App server 03 [2U];
  16: Storage array [4U, description = "24 bay"];
  22: Console;
}

#Making it your own

• Units count from the bottom, as they do in the room.

• Leave gaps out of the list; empty units are capacity, and capacity is why people look.

• Draw the rear as a second rack if cabling or power matters.
