Auto-Logout Timeout – The number of idle minutes before SMU session times
■
out and requires you to log back in, or "No timeout." The default is 30 minutes.
Temperature Display Mode – Fahrenheit or Celsius for all temperature status

Expander Status

Each controller module and expansion module has an Expander Controller (EC) that
manages the module's SAS expander. A SAS expander has 24 serial ports (PHYs)
that are used for communication between the ECs and all disk drives in the storage
system.
The SAS expander uses the following PHY types:
Disk (12), to communicate with the enclosure's disk drives
■
Inter-expander (4), in a controller module only, to communicate with the
■
expander in the partner controller module
SC (4), in a controller module only, to communicate with the Storage Controller
■
Egress (4), to communicate with an expansion port or SAS Out port
■
Ingress (4), in an expansion module only, to communicate with an expansion port
■
When the storage system's PHY isolation feature is enabled, PHYs are monitored
for faults and a PHY is automatically disabled if it experiences too many faults.
For a selected enclosure you can view the status of PHYs managed by each EC. The
status information can identify where faults have occurred in the communication
path.
