Support for RAID Storage Configurations
You can set up hardware RAID 1 (mirroring) and hardware RAID 0 (striping) configurations
for any pair of internal hard drives, providing a high-performance solution for hard drive
mirroring.
By attaching one or more external storage devices to the server, you can use a RAID
software application such as Solstice DiskSuite™ or VERITAS Volume Manager
1 to
configure system drive storage in a variety of different RAID levels.
Error Correction and Parity Checking
The UltraSPARC T2 Plus multicore, multithreaded, 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 T5440 server provides 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 of the 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. This service also
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 T5440 server uses a space-saving 4U-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.
