C.1.1 SSA Loops and Links
In the simplest SSA configuration, SSA devices are connected through two or more SSA links to an SSA adapter that is located in
the system unit. The devices, SSA links, and SSA adapter are configured in loops. Each loop provides a data path that starts at one
connector of the SSA adapter and passes through a link (SSA cable) to the devices. The loop continues through the devices, then
returns through another link to a second connector on the SSA adapter.
The maximum permitted length for an external cable that connects two SSA nodes (for example, disk drives) is 25 meters (82 feet).
Details of the rules for configuring SSA loops are given for each SSA adapter in "Rules for SSA Loops" in topic C.1.2.
