System and I/O Rack Configurations
Model S80 and S85 systems can be set up in various configurations regarding the
placement of the primary I/O drawer. Typically, the primary I/O drawer is installed in an
I/O rack with other drawers attached to the same system rack. If two systems are
installed side-by-side, then the two systems can share one I/O rack by installing both
primary I/O drawers in the same rack. This can be done to save space and also if the
systems are used for high-availability (HA) applications. The following illustrations show
some basic configurations.
