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 Storwize® V3700 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 Storwize V3700 rack, use Table 1 to record the physical configuration of the 2U Storwize V3700 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).

Plan to install all enclosures next to each other. While keeping the rack stable (not top heavy), plan for the enclosures to be at a level that is easy to service (for example, in the middle of rack).

Table 2 describes the components your Storwize V3700 system might include.

Note: The system comprises one control enclosure and zero to four expansion enclosures. The drive types that are supported in the LFF and SFF enclosures are different, so the enclosure "FF" type depends on what drives are required.
