Multiple-step fan speed control
■
The fan speeds are finely adjusted according to the altitude and the ambient
temperature at the installation site of the server. Such adjustments reduce
noise and realize quiet operation well suited for the office environment as well
as reducing power consumption.
High performance server enhanced with the latest architecture
■
SPARC64 VII+ or SPARC64 VII processors
■
The processors provide superior performance, with two or four cores each of
which can execute 2 threads. In addition, the Error Checking and Correction
(ECC) function and the instruction retry function provide high reliability and
high availability.
Power-saving by system LSI
■
By using the 65 nm process technology, system controller and memory access
controller have been packed on a single LSI (Large Scale Integration), which
realizes the power-saving.
Using PCI Express (PCIe) as an I/O bus
■
The PCIe bus having a band of up to eight lanes is used for the interconnect
bus with the I/O device.
High reliability and high availability
■
Data protection with the ECC function
■
ECC function protects data on all system buses and in memory, so that any
errors in data are automatically corrected. In addition to ECC, advanced ECC
memory protection is supported.
Redundant configuration and active/hot replacement of components
■
Hard disk drives, fan units, and power supply units support redundant
configuration and active/hot replacement. In a redundant configuration, the
system can be operated continuously even if one of the components fails.
Faulty components can be maintained/replaced without stopping the system.
Automatic reboot at component failure
■
If a failure occurs, the faulty component is automatically isolated from the
system, and the system is rebooted. If 1-bit errors occur frequently in the cache
memory configuring a CPU, the faulty memory can be dynamically isolated
without rebooting the Oracle Solaris Operating System (Oracle Solaris OS).
These degradation functions enable the business operation to be continued
based on non-faulty resources. The functions thus implement high fault-
tolerance even if a component fails.
