Simple Loop

Figure 2 shows a simple SSA loop. The devices that are attached to the SSA adapter

card 1 are connected through SSA links 2. These SSA links are configured as a

loop. Data and commands to a particular device pass through all other devices on the

link between the adapter and the target device.

Data can travel in either direction round the loop. The adapter can, therefore, get

access to the devices 3 (disk drives in this example) through two data paths. The

adapter always, however, uses the path that has the fewest interconnecting devices

between the adapter and the destination device. The using system cannot detect which

data path is being used.
