SPARC Enterprise T2000 Server Features 11
By attaching one or more external storage devices to the SPARC Enterprise T2000
server, you can use a redundant array of independent drives (RAID) software
application such as Solstice DiskSuite™ or VERITAS Volume Manager to configure
system drive storage in a variety of different RAID levels.
Error Correction and Parity Checking
The UltraSPARC T1 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 3MB L2 cache has parity protection on the tags, and ECC protection on
the data.
Advanced ECC, also called chipkill, 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 T2000 server features 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 T2000 server.
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 T2000 server uses a space-saving 2U-high rackmountable
enclosure that can be installed into a variety of industry standard racks.
