    Balancing Expansion Trays

    Each controller in the Sun StorageTek 6140 Array has two expansion channels. When adding expansion trays, try to connect the expansion trays evenly between the two channels.

    For example, in a 1x3 array configuration, cable one expansion tray to channel 1 of both controllers and the other expansion tray to channel 2 of both controllers. In a 1x5 array configuration, cable two expansion trays to channel 1 of both controllers and two expansion trays to channel 2 of both controllers.

    In an uneven array configuration, such as the 1x4 and 1x6 array configurations, add the extra expansion tray to either channel 1 or channel 2 of both controllers.
