Completing the hardware location chart
Planning for the physical location includes documenting the rack locations of the enclosures and other devices that are based on the requirements of each device.
The hardware location chart represents the rack into which the enclosures are installed. Each row of the chart represents one Electronic Industries Alliance (EIA) 19-inch wide by 1.75-inch tall rack space or unit, each of which is commonly referred to as 1U of the rack. A control enclosure requires 2U of space; depending on the model, expansion enclosures can require 2U or 5U of space.
If the rack contains sufficient space, plan to install the control enclosure in the middle of the rack to minimize the length of the SAS cables that are required to connect expansion enclosures to the control enclosure. Also, due to its size and weight, it is good practice to install a 5U expansion enclosure near the bottom of the rack.
Hardware location planning chart
As you design the rack for your system, use Table 1 to record the physical configuration of the control enclosures, expansion enclosures, and other devices in your system.
