The main components, Power Supply Units, and FAN Units support active (hot)
■
replacement/addition
Component replacement and addition during system operation supported for the
main components, such as a Power Supply Unit, FAN Unit, hard disk drive,
System Control Facility (board), system board, and PCI card, with some
exceptions.
Dynamic reconfiguration (DR) is used for active replacement and addition of
CMU and IOU configuring the system board.
PCI hot-plug (PHP) function enables replacement and addition of PCI Cards
while the system is running.
Automatic reboot on failure
■
If a failure occurs, the faulty component is automatically isolated from the system,
and the system is rebooted. If 1-bit errors occur frequently in the cache memory
configuring a CPU, the faulty memory can be dynamically isolated without
rebooting the Solaris
function enables the operation of the other resources to continue without
interruption, and also provides high fault-tolerance in case of failure.
Uninterruptible Power Supply (UPS) controller
■
For measures against commercial power failure, the server is equipped with UPS
controller (UPC) ports. Using a UPS enables stable power supply to the system
when a power failure or an extensive power interruption occurs.
eXtended System Control Facility (XSCF)
■
This product has a built-in service processor (called the eXtended System Control
Facility (XSCF)), which monitors the system temperature, the hardware status of
the Power Supply Unit and FAN Unit, and the operating status of domains.
You can configure the system to selectively degrade a faulty component for
operation if supply failure is detected.
Scheduling is supported to enable automatic power-on and power-off of the
SPARC Enterprise system according to the specified operation schedule.
The console of each domain can be controlled from the XSCF via a network.
A browser-based user interface (BUI) and the Command- Line Interface (CLI)
facilitate operations for making configuration changes and status monitoring in
the system.
Note – A console display terminal is required for console control. Prepare it before
installation. The devices that can be used as the terminal are listed below.
