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. As you design your rack for your system, use Hardware locations of enclosures and other devices to record the physical configuration of the 2U enclosure, and other devices in your system.
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 (required to connect expansion enclosures to the control enclosure).

A clustered system is a collection of control enclosures that are managed as a single system. Each control enclosure contains two node canisters. The two node canisters within the control enclosure form the node pair that attaches to the SAN fabric.
