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 T5120 and T5220 servers offer 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 (two)
■
Redundant N+1 hot-swappable fan modules
■
Environmental monitoring
