General Description 2-3
The NEC Express5800/ft series achieves fault-tolerant high-availability in a space-saving form
factor by incorporating redundant hardware module pairs in a single chassis. These modules work
in synchronous tight lockstep while constantly making comparisons wit each other and detecting
anomalous diversions in operation.
Even if one hardware module stops, the server can continue operation with the other module. After the failed
module is replaced, the new module will obtain information from the other and resume operation.
NEC Express5800/ft series is a highly fault-tolerant Windows 2000 server that achieves continuous
computing operations, data storage mirror, and continuous network connection. It allows you to
run Windows 2000-based applications.
NEC Express5800/ft series achieves continuous computing operations for the Windows 2000 server
and server-based applications with its redundant CPU processing and redundant memory. It
assures data redundancy through duplication of server data on an independent storage system.
These features eliminate server downtime that is usually caused by network disconnection or trouble
with the I/O controller, Ethernet adapter or disk drive, and support operation of the network and
server applications continuously. While being transparent to application software, NEC
Express5800/ft series achieves high fault-tolerance.
NEC Express5800/ft series detects status changes, errors and other events and notifies the Windows
2000 Event Log of these events. If you use an alarm notification tool, you can configure NEC
Express5800/ft series to notify you when certain events occur.
ESMPRO is installed on the system as a server management solution. ESMPRO, a GUI-based
management tool, allows you to monitor, view, and configure NEC Express5800/ft series. This
tool also supports both local and remote management of NEC Express5800/ft series.
