High Levels Of System Reliability, Availability, And Serviceability - Fujitsu SPARC Enterprise T5440 Overview Manual

You can configure ILOM to send email alerts of hardware failures and warnings, and other
events related to the server. The ILOM circuitry runs independently of the server, using the
server's standby power. Therefore, ILOM firmware and software continue to function when
the server operating system goes offline or when the server is powered off. ILOM monitors
the following SPARC Enterprise T5440 server conditions:
CPU temperature conditions
Hard drive status
Enclosure thermal conditions
Fan speed and status
Power supply status
Voltage conditions
Solaris watchdog, boot time-outs and automatic server restart events
In addition to the ILOM CLI and browser interface, you can set up the server to use an
ALOM CMT compatibility CLI. The ALOM CMT compatibility CLI provides commands
that approximate the ALOM CMT UI that is a system controller interface provided on some
previous servers.
High Levels of System Reliability, Availability, and
Serviceability
Reliability, availability, and serviceability (RAS) are aspects of a system's design that affect
its ability to operate continuously and to minimize the time necessary to service the system.
Reliability refers to a system's ability to operate continuously without failures and to
maintain data integrity. System availability refers to the ability of a system to recover to an
operational state after a failure, with minimal impact. Serviceability relates to the time it
takes to restore a system to service following a system failure. Together, reliability,
availability, and serviceability features provide for near-continuous system operation.
To deliver high levels of reliability, availability, and serviceability, the SPARC Enterprise
T5440 server offers the following features:
Ability to disable individual threads and cores without rebooting
Lower heat generation, reducing hardware failures
Hot-pluggable hard drives
Redundant, hot-swappable power supplies (four)
Redundant N+1 hot-swappable fan modules
Environmental monitoring
Internal hardware drive mirroring (RAID 1)
Error detection and correction for improved data integrity
