General Information
These components are used with the SSA model 020.
Use of internal bypass is allowed.
The cabling diagrams only deal with a single loop. For double loop, the physical connections
must be doubled. The second loop can be set up on the same adapter or on a second one,
in which case two adapters give a higher availability.
Disk mirroring can be implemented across two loops, through the standard features of the
AIX system. (Disks on a loop are mirrored to disks on the other loop).
Standard cable length is 10m (MI CBLG162-1900). When several cable types are part of the
configuration, start to use the larger cables and end with the shorter ones.
