12 SPARC Enterprise T5120 and T5220 Servers Overview Guide • August 2007
By attaching one or more external storage devices to the SPARC Enterprise T5120
and T5220 servers, you can use a redundant array of independent drives (RAID)
software application such as Solstice DiskSuite™
1 or VERITAS Volume Manager to
configure system drive storage in a variety of different RAID levels.
Error Correction and Parity Checking
The UltraSPARC T2 multicore processor provides parity protection on its internal
cache memories, including tag parity and data parity on the D-cache and I-cache.
The internal L2 cache has parity protection on the tags, and ECC protection on the
data.
Advanced ECC, corrects up to 4 bits in error on nibble boundaries, as long as they
are all in the same DRAM. If a DRAM fails, the DIMM continues to function.
Fault Management and Predictive Self Healing
The SPARC Enterprise T5120 and T5220 servers provide the latest fault management
technologies. The Solaris 10 OS architecture provides a means for building and
deploying systems and services capable of predictive self-healing. Self-healing
technology enables systems to accurately predict component failures and mitigate
many serious problems before they actually occur. This technology is incorporated
into both the hardware and software of the SPARC Enterprise T5120 and T5220
Servers.
At the heart of the predictive self-healing capabilities is the Solaris ™ Fault Manager,
a new service that receives data relating to hardware and software errors, and
automatically and silently diagnoses the underlying problem. Once a problem is
diagnosed, a set of agents automatically responds by logging the event, and if
necessary, takes the faulty component offline. By automatically diagnosing
problems, business-critical applications and essential system services can continue
uninterrupted in the event of software failures, or major hardware component
failures.
Rackmountable Enclosure
The SPARC Enterprise T5120 and T5220 servers use a space-saving 1U or 2U-high
rackmountable enclosure that can be installed into a variety of industry standard
racks.
1. Software RAID applications such as VERITAS Volume Manager are not included with this server. You must
obtain and license them separately.
